1. Safety Precautions

This product complies with the requirements of the following

European Community Directives: 2004/108/EC (Electromagnetic

Compatibility) and 2006/95/EC (Low Voltage) as amended by

2004/22/EC (CE-Marking). Overvoltage category III 600V;

pollution degree 2.

CAT I: For signal level, telecommunication, electronic with

small transient over voltage

CAT II: For local level, appliances, main wall outlets, portable

equipment

CAT III: Distribution level, fixed installation, with smaller transient

overvoltages than CAT IV.

CAT IV: Units and installations, which are supplied overhead

lines, which are stand in a risk of persuade of a

lightning, i.e. main-switches on current input,

overvoltage-diverter, current use counter.

To ensure safe operation of the equipment and eliminate the

danger of serious injury due to short-circuits (arcing), the following

safety precautions must be observed.

Damages resulting from failure to observe these safety

precautions are exempt from any legal claims whatever.

* Do not use this instrument for high-energy industrial

installation measurement.

* Do not exceed the maximum permissible input ratings (danger

of serious injury and/or destruction of the equipment).

* The meter is designed to withstand the stated max voltages. If

it is not possible to exclude without that impulses, transients,

disturbance or for other reasons, these voltages are exceeded

a suitable prescale (10:1) must be used.

* Disconnect test leads or probe from the measuring circuit

before switching modes or functions.

* To avoid electric shock, disconnect power to the unit under

test and discharge all capacitors before taking any resistance

measurements.

-20-

* Check test leads and probes for faulty insulation or bare wires

before connection to the equipment.

* To avoid electric shock, do not operate this product in wet or

damp conditions. Conduct measuring works only in dry

clothing and rubber shoes, i. e. on isolating mats.

* Never touch the tips of the test leads or probe.

* Comply with the warning labels and other info on the

equipment.

* Always start with the highest measuring range when

measuring unknown values.

* Do not subject the equipment to direct sunlight or extreme

temperatures, humidity or dampness.

* Do not subject the equipment to shocks or strong vibrations.

* Do not operate the equipment near strong magnetic fields

(motors, transformers etc.).

* Keep hot soldering irons or guns away from the equipment.

* Allow the equipment to stabilize at room temperature before

taking up measurement (important for exact measurements).

* Do not input values over the maximum range of each

measurement to avoid damages of the meter.

* Do not turn the rotary function switch during measurement,

otherwise the meter could be damaged.

* Use caution when working with voltages above 35V DC or

25V AC. These Voltages pose shock hazard.

* Replace the battery as soon as the battery indicator appears.

With a low battery, the meter might produce false reading that

can lead to electric shock and personal injury.

* Fetch out the battery when the meter will not be used for long

period.

* Periodically wipe the cabinet with a damp cloth and mid

detergent. Do not use abrasives or solvents.

* The meter is suitable for indoor use only

* Do not operate the meter before the cabinet has been closed

and screwed safely as terminal can carry voltage.

* Do not store the meter in a place of explosive, inflammable

substances.

* Do not modify the equipment in any way

* Opening the equipment and service- and repair work must

only be performed by qualified service personnel

* Measuring instruments don’t belong to children hands.

Cleaning the cabinet

Clean only with a damp, soft cloth and a commercially available

mild household cleanser. Ensure that no water gets inside the

equipment to prevent possible shorts and damage to the

equipment.

1.1. Safety information

Caution! Refer to accompanying documents.

Caution! Risk of electric shock.

Equipment protected throughout by double insulation

(class II)

Alternating current

Direct current

Ground

However, electrical noise or intense electromagnetic fields in the

vicinity of the equipment, may disturb the measurement circuit.

Measuring instruments will also respond to unwanted signals that

may be present within the measurement circuit. Users should

exercise care and take appropriate precautions to avoid

misleading results when making measurement in the presence of

electromagnetic interference.

COM Terminal

This is the negative (ground) input for all measurement modes

except current. Connection is made to it using the black test leads.

V/Hz/Ω

ΩΩ

ΩInput Terminal

This is the positive input terminal for voltage, capacitance,

frequency, ohms and diode measurements. Connection is made

to it using the red test lead.

Display

The display indicates the measured value of a signal, function

mode symbols and bargraph.

Function/Range selector rotary switch

This rotary switch selects the function and selects the desired

range (current measurements).

Hold Button

Press HOLD button to toggle in and out of the Data Hold mode. In

the Data Hold mode, the “HOLD” annunciator is displayed and the

last reading is frozen on the display. Press the HOLD button again

to exit and resume readings.

REL- Button

Press ZERO button to enter the relative mode, the ZERO ∆

annunciator turns on, zero the display and store the displayed

reading as a reference value. Press and hold down the ZERO

button for 2 seconds to exit the relative mode.

In the relative mode the value shown on the LCD is always The

difference between the stored reference value and the present

reading. For example, if the reference value is 24.000 V and the

present reading is 12,50 V the display will indicate –11,50 V. If the

new reading is the same as the reference value, the display will be

zero. This feature also is made as DCA ZERO adjustment.

Transformer jaws

Pick up the AC or DC current flowing through the conductor.
