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 (
)
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 read
-
ing 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.

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 (
)
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 ap

Measurement of AC current (
)
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 results, center the conductor in
the clamp meter.

In the frequency measurement function:
Connect the red probe cable to the “INPUT” socket, and the black one
to the “COM” socket. Set the dial to the frequency measurement func
-
tion (HZ%). Use the “Hz%” button to set the frequency measurement
function (Hz). Connect the measurement probes to the circuit to be
measured. Note: Do not exceed the input voltage, as this will damage
the instrument.

Use the “SEL” pushbutton to set the alternating current (AC) function.
Use the “Hz%” button to set the frequency measurement function (Hz).
