When clamping 2 or more cables to measure leakage
current, the result may be interfered by the current on the
cable. The deviation may be more than 1mA when the
current on the cable is 1 Amp.

Electric shock hazard. Remove the probe measuring with
current clamp.
1)1) Measuring switch is placed to positio A. At this time, the
meter is in AC current measurement state. Choose appropri-
ate measuring range.
1) Clamping two or more leads of circuit to be tested
simultaneously will not get the correct measuring results.
1) Turn the transfer switch to turn on the power. When battery
voltage is low (about2.4V), LCD displays " " symbol,
replace the battery.
2)2) " " symbol means that input voltage or current should not
be more than the specified value, which is to protect the
internal line from damage.
3) Place transfer switch to required measuring function
and range.
4) When connecting line, first connect the common test line,
then connect charged test line. When removing line, remove
charged test line first.
2) Hold the trigger, open clamp head, clip one lead of measure-
ment circuit to be tested in the clamp.
3)3) Read the current and frequency value on the LCD displ .
