clamp, measures AC/DC voltage, resistance, continuity, frequency, duty

cycle and capacitance, and tests diodes via test-leads. It features a Low

impedance (LoZ) mode for identifying and eliminating ghost or stray

voltages, and has a dedicated mode for capturing inrush current.

WARNINGS

To ensure safe operation and service of the meter, please follow these

instructions. Failure to observe these warnings can result in severe

injuryor death.

• Before every use, verify meter operation by measuring a known

voltageor current.

• Never use the meter on a circuit with voltages that exceed the

category-based rating of this meter.

• Do not use the meter during electrical storms or in wet weather.

• Do not use the meter or test leads if they appear to be damaged.

• Use only with CAT III- or CAT IV-rated test leads.

• Ensure that meter leads are fully seated and keep fingers away from

the metal probe contacts when taking measurements.

• Use caution when working with voltages above 25 V AC RMS or

60 V DC. Such voltages pose a shock hazard.

• To avoid false readings that can lead to electric shock, replace

batteries when a low-battery indicator appears.

• Do not attempt to measure resistance or continuity on a live circuit.

• Do not hold the meter above the hand and finger guard during use.

WARNINGS

• Always adhere to local and national safety codes. Use personal

protective equipment to prevent shock and arc blast injury where

hazardous live conductors are exposed.

• Usage of this meter in any way other than that specified by the

manufacturer can impair safe operations, resulting in severe injury

ordeath.

• To avoid the risk of electric shock, disconnect leads from any voltage

FUNCTION BUTTONS

ON/OFF

To switch the meter ON, rotate the Function selector switch

from

the OFF setting to any measurement setting. To switch the meter OFF,

rotate the Function selector switch

to the OFF setting. By default,

the meter will automatically switch itself OFF after aprox. 30minutes

of inactivity. To deactivate the auto power OFF functionality, press

and hold the 'SEL/DC ZERO' button

before switching ON from

the OFF setting. When auto power OFF is deactivated, the Auto power

off icon will not be visible in the display.

SEL (SELECT)/DC ZERO BUTTON (FOR SECONDARY FUNCTIONS)

The SEL/DC ZERO button

activates the secondary function for

each application accessible by the function selector switch

• In Current

and Low impedance modes, it toggles

between AC and DC measurements.

• In the Frequency/Duty cycle

setting, it toggles between

these measurements

• In the Continuity/Resistance/Diode-test

setting, it toggles

through these measurements in order

• In the DC current setting, pressing and holding for more

than one second initiates the DC ZERO function. Subsequent

DC current measurements will automatically subtract the

measurement that was present as an offset correction.

The default function for each application is printed on the meter in

white, with the secondary functions in orange. An icon on the LCD

display will indicate which function is active.

DATA HOLD

Press the Data hold/Backlight/ button

to hold the measurement

on the display. Press again to release the display to return to live

measuring.

BACKLIGHT

Press and hold the Data hold/Backlight/ button

for more

than one second to turn the backlight ON. The backlight will

automatically switch itself OFF after three minutes of inactivity.

RANGE

The meter defaults to auto-ranging mode

AUTO

. This mode

automatically determines the most appropriate measurement range

for the testing that is being conducted. To manually force the meter

to measure in a different range, use the Range button

1. Press the 'RANGE' button

to select the measurement range

manually (AUTO will be deactivated on the LCD). Press the

'RANGE' button repeatedly

to cycle through the ranges

available, stopping once the desired range has been reached.

2. To return to auto-ranging mode, press and hold the 'RANGE'

button

for more than one second (AUTO will be reactivated).

ENGLISH

FUNCTION BUTTONS

MAX/MIN

When the 'MAX/MIN' button

is pressed, the meter keeps track

of the maximum and minimum values, as the meter continues to

take samples.

1. When measuring, press the 'MAX/MIN' button

to toggle

between the maximum value (MAX) and the minimum value

(MIN). If a new maximum or minimum occurs, the display will

update with the new value.

2. Press the 'MAX/MIN' button

for more than one second to

return to normal measuring mode.

INRUSH CURRENT

Rotate the Function selector switch

to the Current

setting

and

press INRUSH

prior to an inrush event to test for inrush

current. While the meter monitors current waiting for the inrush

event, '----' will be visible on the display.

NON-CONTACT VOLTAGE TESTING

Press and hold the 'NCV' button

to test for AC voltage using

the integrated non-contact voltage tester. Approach the conductor

under test leading with the sensing antenna

. The meter delivers

visual warning signals via the LED indicator

and signals audibly

(beeps) when AC voltage is detected. Release the 'NCV' button to

exit NCV testing mode.

NOTE: We do not recommend performing continuity and NCV

testing simultaneously, as both tests use the same audible signal,

making it difficult to resolve which test is responsible for the

audible alarm.

NOTE: Only voltages of 90 V AC or greater will be detected.

OPERATING INSTRUCTIONS

CONNECTING TEST LEADS

Do not test if the leads are improperly seated. Results could cause

intermittent display readings. To ensure a proper connection, press

the leads firmly into the input jack.

TESTING IN CAT III/CAT IV MEASUREMENT LOCATIONS

Ensure that the test lead shield is pressed firmly into place. Failure

to use the CATIII/CATIV shield increases the risk of arc flash.

TESTING IN CAT II MEASUREMENT LOCATIONS

CAT III/CAT IV shields may be removed for CAT II locations. This

will allow testing on recessed conductors, such as standard power

sockets. Take care not to lose the shields.

OPERATING INSTRUCTIONS

AC/DC CURRENT (LESS THAN 2,000 A)

AC current is measured by pressing the

clamp trigger

to open the clamp

and

placing it around a wire carrying a current.

When measuring, care should be taken to

ensure that the clamp is

completely

closed, with the trigger

fully released, and

that the wire passes perpendicularly through

the centre of the clamp

in line with the

arrow markings

To measure current:

1. Rotate the Function selector switch

to the

Current

setting

2. The meter defaults to AC measurement.

To measure DC, press

the 'SEL/DC ZERO' button

to toggle between AC and DC

modes. The AC or DC icon on the LCD

indicates which mode has been selected.

Note 'AC' or 'DC' on the display.

3. Place the clamp

around the wire.

When measuring DC current, align the

polarity markings

on the clamp with

the polarity of the wire to avoid negative

readings. The current measurement will be shown on the display.

The meter will auto-range to display the measurement in the

most appropriate range.

To measure inrush current:

1. Rotate the Function selector switch

to the Current

setting.

Place the clamp

around the wire and press 'INRUSH'

. The

display

will show '----'. Initiate the inrush event and the inrush

current will be captured and presented in the display. Pressing

'INRUSH' a second time

will reset the inrush measurement,

'----' will be presented on the display and the meter will wait for

the next inrush event.

2. P

ress and hold

'INRUSH'

for more than one second to return

to normal measuring mode.

Disconnect test leads when measuring with the clamp.

NOTE: If non-zero values are displayed prior to measuring in DC

current mode, an offset correction is required to improve accuracy.

With the meter in DC current mode, press and hold the

'SEL/DC ZERO' button

for more than one second to initiate the

DC current ZERO function. Subsequent DC current measurements

will automatically subtract the measurement that was initially

present as an offset correction.
