—The multimeter must be operated only by persons who understand the

danger of shock hazards and know how to apply safety precautions.

Shock hazards exist wherever voltages of more than 30 V (TRMS) can

appear.

—Do not work alone in shock hazardous environment while carrying out

measurement.

—The maximum permissible voltage between any of the terminal sockets

(7) and ground is 1000 V.

—Take into account that unexpected voltages can occur on devices under

test (e.g. defective instruments). Capacitors may be charged to a

dangerously high voltage, for instance.

—Verify that the test leads are in good condition, e.g. no cracked insulation,

no open circuits in the leads or connectors.

—This meter must not be used for measurements on circuits with corona

discharge (high voltage).

—Be particularly careful when measuring on HF circuits. Dangerous

composite voltages may exist there.

—Measurements under moist environmental conditions are not permitted.

—Do not exceed the permissible overload limits of the measuring ranges.

See Table “measuring ranges” under “17. Specifications”.

—All current measuring ranges, are fused. The maximum permissible

voltage of the measuring circuit (=nominal voltage of the fuse) is 1000 V

AC/DC on the “mA” ranges, “A” ranges.

—You must only use the meter in power systems, when the current circuit is

protected by a fuse or a circuit breaker of 20 A, and when the nominal

voltage of the system does not exceed 1000 V.

For safe voltage measurements on power systems, up to 1000 V we

recommend the KS30 measuring adapter, which is available as accessory. Its

internal resistance limits the measuring current in the case of overvoltage and

incorrect operation and safely suppresses sparking from spark gaps. Also

refer to Section “7.1 Voltage measurement on electrical systems upto 1000V

with the KS30 measuring adapter”.

1. Safety features and safety precautions

You have chosen a meter which offers you a very high degree of safety.

The analog/digital multimeter Gamma 10 is manufactured in compliance

with the safety standards IEC 61010-1:2001.

In case of incorrect use or careless handling, the safety of both user and

multimeter is not assured.

To maintain the safe and proper condition of the meters and to ensure

their safe operation, it is absolutely necessary to carefully and

completely read these operating instructions before using any meter.

These instruction must be followed in all respects.

For your safety and for protection of the meter, the Gamma 10 meter is

fitted with an automatic terminal blocking system. It is coupled with the

function selector switch, which blocks the terminal sockets not necessary

for measurement.

Please note the following safety precautions:

Fuse replacement

Open the meter same as for battery replacement.

Remove the blown fuse, e.g. with the aid of a probe, and replace it with

a new one.

permissible types

- for current measuring ranges up to 300mA:

Type FF(UR) 1.6A / 1000V AC/DC; (10kA); 6.3mm x 32mm

- for the 3A and 10A current measuring ranges :

Type FF(UR) 1.6A / 1000V AC/DC; (30kA); 10mm x 38 mm

Caution :

Absolutely verify that the specified fuse is installed!

If a fuse of other cut-out capacity, other nominal current or other switching

capacity is used, a dangerous situation exists for you, and there is danger of

damaging protective diodes, resistors or other components.

The use of mended fuses of shorting of the fuse holder is not permissible.

18.3 Case

Special maintenance of the case is not required. Take care that the surface

between the connection sockets is clean. For cleaning take a moist cloth.

Avoid scrabbing.

19 Repair and replacement parts service

20. Appendix

20.1 AC current measurement with (clip-on) current

transformers

20.1.1 Transformer output mA/A

Caution :

If current transformers are operated with an open circuit on the secondary side,

e.g. due to defective or disconnected leads, a blown fuse in the meter, or a wrong

connection, dangerously high voltages can occur at the connectors. Therefore,

verify that the current circuit of the meter and the secondary winding of the

transformer connected to the meter form an intact circuit. Connect the transformer

to the sockets ^ and mA and/or A.

The maximum permissible operating voltage is the nominal voltage of the current

transformer. When reading the measured value, take into account the transformer

ratio and the additional error in indication.

20.1.2 Transformer output mA/A

Several transformers are fitted with a voltage output (designation mV/A).

The secondary output must therefore be connected to the connection sockets ^

18. Maintenance

Caution :

Disconnect the meter from the measuring circuit before you open

it to replace the battery or the fuse !

18.1 Battery

Prior to initial start-up, or after storage of your meter, verify that the battery of

your meter does not leak. Repeat this check in regular short intervals. If the

battery leaks, completely remove the battery electrolyte carefully with a moist

cloth and install a new battery before you operate your meter again.

When the symbol “ ” (17) appears on the LCD (1), replace the battery as

soon as possible. You can continue to measure, but a reduced measuring

accuracy must be taken into account.

The meter operates with a 9 V flat cell battery according to IEC 6F 22 or IEC 6

LR 61 or with a suitable NiCd storage battery.

Replacing the battery

êplace the meter on its face, loosen the two screws on the rear and

remove the lower part of the case, lifting it from the bottom. The lower and

the upper part of the case are fixed together at the top on the front by

means of detent hooks.

êRemove the battery from the battery compartment and carefully

disconnect the contacts from the battery.

êSnap the connection contacts to a new 9V battery and insert the battery

into the battery compartment.

êReplace the lower part of the case. Start at the top on the front and take

care that the detent hooks are properly engaged at this point.

êTighten the lower part with the two screws.

êPlease destroy the batteries in an environmental friendly way.

18.2 Fuses

A blown fuse is signaled on the LCD display the instant a measured quantity

having a voltage of more than 4V is applied to the corresponding connection

sockets. Then, the digital display (9) shows “FUSE”. The 16 A fuse interrupts

the 3 A and 10 A ranges, the 1.6 A fuse all other current measuring ranges.

All other measuring ranges continues to function. When a fuse blows, first

eliminate the cause of the overload before using the meter again!

Repair, replacement of parts and calibration

When opening the meter, live parts may be exposed. Therefore, the meter

must be disconnected from the measuring circuit prior to opening its case

for repair, replacement of parts or calibration. If repair or calibration cannot

be avoided unless the meter is open and live, this work must only be

performed by a qualified person who understands the danger involved.

Faults and extraordinary stress

When it must be assumed that safe operation is no longer possible, take

the meter out of service and secure it against accidental use. It is assumed

that safe operation is no longer possible.

—when the meter shows obvious signs of damage,

—When the meter no longer functions correctly,

—after prolonged storage under adverse conditions,

—Due to sever stress during transportation.

2. Switching the meter on Battery

Fit the meter with 9 volt flat cell battery provided along with the meter.

Before you use the meter for the first time or after storage,

absolutely refer to Section “18.1 Maintenance Battery”.

Switching the meter on

íPress the “ON/OFF” pushbutton (2).

Switch-on is acknowledged by a sound signal. As long as you keep the

push-button pressed, all segments of the liquid crystal display (LCD) will

appear. The LCD is shown on page 2.

After the pushbutton is released, the meter is ready for operation.

Note :

Electric discharge and high frequency interference may cause incorrect

information to be displayed and block the measuring process. Reset the

meter by switching it OFF and ON again. Otherwise, check the battery

connections.

Disconnect the meter from the measuring circuit before you open

it and see section “18. Maintenance”!

Automatic turn-off

Your meter turns off automatically, when the measured value remains

constant (variations of the measured value < ± 20 digits) for about 10

minutes and when neither a pushbutton nor the function selector switch is

operated during that time.

How to prevent automatic tun-off

Switch your meter to “CONTINUOUSLY ON” mode.

íTo do this, press the yellow multi-function pushbutton (5) and the

“ON/OFF” pushbutton (2) together. The function “CONTINUOUSLY ON”

is shown on the LCD (1) by the symbol (8).

4. Liquid crystal display

4.1 Digital display

The digital display (9) shows the measured value with correct location of decimal

point and sign. The selected measuring unit (12) and the function (11) are

simultaneously displayed. When measuring DC quantities, a minus sign appears

in front of the digits, when the positive pole of the measured quantity is applied to

the “ ^ ” input terminal. When exceeding the upper range limit 30999 [on the

range F:3099], “OL” is displayed.

With V, A and W measurements, the digital display is updated two times per

second.

Condition Meter reaction

4.2 Analog indication

The analog indicator with pointer presentation gives the dynamic response of a

moving coil movement and is updated 20 times per second. Analog indication

is of particular advantage when observing variations of measured values and

for calibration procedures.

The analog indicator has its own polarity indication.

When measuring DC quantities. the analog scale (15) has a negative range of

5 scale divisions. so that variations of the measured values around “zero” can

be observed exactly. When the measured value exceeds the range of

indication, the left triangle (16) is shown before the polarity of the analog

indicator switches over after approximately 0.7s. Exceeding of the measuring

range (>30999 digits, on the range F:>3099) is shown by the right triangle(13).

The graduation of the analogue scale is automatic which is helpful for the

manual range selection.

4.3 Backlit

The instrument is provided with user selectable Backlit for measurements in

poor light conditions or dark area.

Switching the Backlit ON and OFF:

By pressing “AUTO/MAN/MAX” keys simultaneously the Backlit can be switched

ON. And by pressing the same keys simultaneously Backlit can be switched

OFF.

5 “DATA” hold / compare facility

The DATA (hold) function allows you to automatically “hold” measured values

This is particularly useful, for instance, when applying the probes to the

measuring point requires full attention. When the measured value is applied

and the “condition” according to the table shown below is met, the meter holds

the measured value on the digital display and issues a sound signal. The

probes can now be removed from the measuring point and the measured

value on the digital display (9) can be read. When the measured value falls

below the limit specified in the table, the meter is reactivated for a new storage.

If the new stored value differs by less than 100 digits from the previous value

the sound signal is issued twice (DATA-Compare)

MIN/MAX MIN/MAX

2) Referring to AC values.

3) When storing a value for the first time twice a sound signal.

For following “holds” only twice if actual hold value differs from first stored value

by less than 100 digits.

The analog indication is not influenced by the DATA hold. You can still read the

actual measured value. Note that with a “held” digital display, the location of the

decimal point is also held.

As long as the DATA hold function is active, manual range selection is not

possible.

The DATA hold function is switched off, when the “DATA” pushbutton (3) is

pressed for approximately 1s, when the function selector switch (6) is operated,

or when the meter is turned OFF and ON again.

6. Minimum value and maximum value “MIN/MAX”

storage facility with time display

With the MIN/MAX function, you can “hold” the minimum and the maximum

measured value which was applied to the input of the meter after activating

MIN/MAX. The most important application is the determination of the

minimum and the maximum value for long-term monitoring of measured

quantities.

The function “MIN/MAX” can be activated in all ranges except for the diode

test. However, for frequency and capacitance measurement the relative

time display is not possible.

MIN/MAX does not influence the analog indication; you can still read the

actual measured value.

Apply the measured quantity to the meter and select the measuring range

prior to activating the MIN/MAX function.

With the function activated, you can only select the measuring ranges

manually. However, the stored MIN/MAX values are cleared.

The MIN/MAX function is switched off, when the MIN/MAX pushbutton (3) is

pressed for approximately 1s, when the function selector switch (6) is

operated or when the meter is turned OFF and ON again.

Notes :

On the 1000 V range, an intermittent sound signal warns you, when the measured

value exceeds the upper range limit.

Caution :

Ensure that a current measuring range (“mA” or “A”) is not selected, when you

connect your multimeter for voltage measurements! When the cut-out rating of

the fuses is exceeded because of incorrect operation, a dangerous situation

exists!

Zero adjustment on the 300 mV --- measuring range

You can adjust the zero on the 300 mV --- measuring range :

Connect the test leads to the meter and join the free ends.

After having selected the measuring range, briefly press the yellow multi

function pushbutton (5).

The meter acknowledges zero setting by a sound signal, the LCD shows

“000.00”(+1digit) and the symbol “ZERO” (18) is displayed. The voltage

displayed the instant the pushbutton is pressed is used as reference value

(max. + 2000 digits). It is automatically deducted from the values measured

thereafter you can clear the zero adjustment

®by pressing the yellow multi-function pushbutton (5) for a long time,

clearance is acknowledged by the buzzer sounding twice.

®by switching the instrument off.

7.1 Voltage measurement on electrical systems up to 1000 V with

the KS30 measuring adapter

On low-voltage systems, transient over voltages of several kilovolts can occur

due to switching function or lightning discharges. Direct connection of your

multimeter to such systems for voltage measurement can, therefore, be

dangerous. For voltage measurements on power systems with nominal

voltages up to 1000 V. use the KS30 measuring adapter. It is an adapter for

multimeters which eliminates danger caused by overvoltages and incorrect

operation of the multimeter. It provides the following protective functions :

—Protection of the input circuit to the voltage measuring range of multimeters.

The internal resistance of the KS30 limits the current in the case of

overvoltage.

—Overload capacity : continuously 1000Vms transient (rise 10ms/fall 1000ms)

6kV max

—Safe suppression of sparking from spark gaps after overvoltage.

—Current limitation in the case of incorrect operation (e.g applying a voltage

to a current input)

—Using the measuring adapter KS30 the additional measured fault is approx.

2%. Voltages above 1000 V can be measured with a high voltage probe,

provided the necessary safety precautions are taken!

7.2 AC level measurement (dB)

êSet the function selector switch (6) to V~.

Briefly press the multifunction button (5).

The function level measurement is activated now. The measured value is

calculated from the true rms value of the AC voltage (300 mV... 1000 V) and

displayed on the LCD display (9). The reference value is taken as dB=0.775V

(1mW on 600W). The corresponding AC voltage is displayed on the analog

scale.
