1 Measuring jaws: Can be
used to measure conductors. To
achieve an accurate
measurement result, the
conductor must be located in
an enclosed area between
the jaws.
Padlock release button (trigger):
Used to open or close the
measuring jaws.

„COM” socket: For
connecting the black (negative)
test lead.

„V Ω” socket: For connecting
the red (positive) test lead.

Function selector (rotary)
knob: Used to select the desired
measuring function and range
and to switch the padlock on / off.
6 “H” key:
After pressing the
key, the currently measured
value remains fixed on the
display, while is displayed in
the upper right corner of the
display. To deactivate the mode, press the key again
7 Relative measurement mode: The Relative mode
permits the user to store a reference reading and
compare all subsequent readings to the stored reference
value by pressing the „ REL ” button the instrument will
store the valued measure as 0. Subsequent readings
will display a value that is the difference between
the actual reading and the stored reference value.
1. Press the „
REL
” key when the desired valued is
displayed on the meter. This becomes the stored
reference. The „
REL
” symbol will appear on the LCD.
2. Take measurements and note that the meter displays
the actual reading minus the reference reading.
3. Press the „
REL
” key to return to normal operation. The
„ REL ” symbol will switch off.
8 „SET” button:
mode selection button between /
and / measuring modes.

Switching the display backlight on / off
It can be switched on after turning the rotary switch of the
device. The backlight can be turned off after the device’s
rotary switch is set to OFF, or after a few seconds the device
will turn off the backlight automatically.
DC voltage measurement
Insert the black test lead into the „
COM
” socket and the red
into the „ INPUT ” socket.
Set the rotary selector to the position and switch to
the AC position with the SET button.
Touch the test leads to the source to be measured.
The measured value can be read on the display.
AC voltage measurement
Insert the black test lead into the „ COM ” socket and the red
into the „
INPUT
” socket.
Set the rotary selector to the position and switch to
the AC position with the SET button.
Touch the test leads to the source to be measured.
The measured value can be read on the display.
AC current measurement
Set the function selector to according to the
measurement.
Press the trigger to release the jaws and then grasp the
conductor in the enclosed area. Make sure the jaws close
well. The measured value can be read on the display.
Note:
Let’s measure one conductor at a time!
The values of the phase running in one line and the zero
sine cancel each other out, the measured value will be 0!
Do not touch the measured conductor by hand, even if you
are sure that it is perfectly insulated.
Resistance measurement
Insert the black test lead into the „
COM
” socket and the red
into the „ INPUT ” socket.
Set the rotary selector to the position.
Touch the test leads to the source to be measured.
The measured value can be read on the display.
Note:
Before measuring resistance, make sure that the
