For comparing mechanical meter: Press “Hold” to start accumulation when the round disk
rotates for one round; press “HOLD” again to stop accumulation when the round disk rotates
for another round, as shown below:

For comparing electronic meter: Press “Hold” to start accumulation when the LED flashes for
one time, press “HOLD” again to stop accumulation when the LED flashes again, as shown
below:

For comparing fixed electric energy meter: Take 0.1kWh as an example, press “HOLD” to start
accumulation when the value changes by 0.1kWh; press “HOLD” again to stop accumulation
when the value changes by 0.1kWh again, as shown below:

Note:
Phase angle is in reference to voltage.
Do not input voltage over 1000V. It is possible to measure higher voltage, but it may damage
the clamp.
Avoid electric shock when working with high voltage.
Disconnect test leads with the measured circuit after all measurement operations are
completed.
The high voltage warning symbol “ ” will appear on the LCD if the measured voltage is
over 30V AC; the red backlight flashes if the measured voltage is over 1000VAC.
Do not release the trigger abruptly when pressing and holding it. Hall sensor is sensitive to
magnet, heat and mechanic stress, impact can cause reading variation in a short time.
To ensure measurement accuracy, please place the measured conductor at the center of the
clamp jaws. Error of ±1.0% of reading will be produced if the measured conductor is not
placed at the center of the clamp jaws.
Incorrect wire connection will cause negative active power and cause the red backlight to
flash, please check if the connections of voltage input terminal and clamp jaws are correct.
