maximum figure. Each push of the button shifts to
the next function. Keep ing the button pressed for
approx. 2 seconds will cause the clamp meter to
leave the MIN/MAX function.
REL
Relative value. The current reading is stored at the
moment the button is pressed, the “REL” symbol
appears on the display and the display is cleared.
Afterwards, the reading appearing on the display will
be of a value relative to the previous one. Pressing
the button again or changing functions will cause
the instrument to clear the relative reading. Keeping
the button pressed for approx. 2 seconds turns off/
activates the automatic power off function.
B.L/HOLD
Pressing this button will store the measured
reading on the display. Pressing the button again or
changing functions will cause the instrument to clear
the data. Keeping the button pressed for approx. 2
seconds turns off the display backlight and the clamp
meter’s illumination for approx. 30 seconds.
Hz/Duty
Frequency/duty factor measurement toggle button.
Each push of the button shifts to the next function.
Input sockets
COM
common input socket for all quantities to be measured
(negative)
INPUT
Common input socket for all quantities to be measured
(positive)
Accuracy
Accuracy is ensured for one year after calibration, at an operating
temperature of 18 °C–28 °C and a relative humidity of 0%–75%.
FEATURES
Automatic power off
In order to conserve power, the multimeter automatically switches
off after approx. 15 minutes if no measurement is performed or
function is changed. This is indicated by 5 short beeps 1 minute
before switching off then the unit switches into sleep mode with a
beep. Pressing any button will wake up the clamp meter.
DC voltage measurement ( V)
Connect the red probe cable to the “INPUT” socket, and the
black one to the “COM” socket. Set the dial to the DC voltage
position. Connect the measurement probes to the circuit to be
measured.
Note:
The reading can be unstable, especially in the 400mV
measurement range, if the probe cable is not connected to the
circuit being measured. If the measured figure is more than 600
V, the “OL” symbol will appear on the LCD display, and the built-in
buzzer will emit a beep.

DC measurement (A )
Warning! Before performing a measurement, unplug the probe
cables from the unit. Set the dial to the desired measurement
range. Use the “
SEL
” pushbutton to set the direct current (
DC
)
function. Clear the display by pressing the “
REL
” pushbutton.
Open the clamp, place it around the cable then close it. The
measured figure can be read off the display.
Note:
Only measure one conductor at a time. For optimum
results, center the conductor in the clamp meter.

Measurement of AC voltage (~V)
Connect the red probe cable to the “INPUT” socket, and the
black one to the “COM” socket. Set the dial to the AC voltage
position. Connect the measurement probes to the circuit to be
measured.
Note:
If the measured figure is more than 600 V RMS AC, the
“OL” symbol will appear on the LCD display, and the built-in
buzzer will emit a beep.

Measurement of AC current (A )
Warning! Before performing a measurement, unplug the probe
cables from the unit. Set the dial to the desired measurement
range. Use the “SEL” pushbutton to set the alternating current
(AC) function. If the displayed figure is unstable, clear the display
by pressing the “REL” pushbutton. Open the clamp, place it
around the cable then close it. The measured figure can be read
off the display.
Note:
Only measure one conductor at a time. For optimum
