5. Operate Method
5.1. Start-up, Shutdown
Press
POWER
key to start up, LCD display; Press the
POWER
key again to shut down. The
meter start up after 5 minutes, LCD will flashes and indicate that will auto shut down, continue
flashes 30s will shut down formally to reduce battery consumption. In case you press
POWER
key
when LCD are flashing, the meter will continue to working 5 minutes. If LCD display is dark after
start up, it might battery voltage is low, please replace battery.
5.2. Current Measurement
High voltage, extremely dangerous! Must be operated by trained and authorized
personnel. The operator must strictly follow the safety rules, otherwise there would
be danger of electric shock, causing personal injury or injury accident.
Dangerous
！
Cannot be used to measure the voltage line exceed 600V, otherwise
there would be danger of electric shock, causing personal injury or injury accident
5.2.1. Start up the meter
5.2.2. Rotate the lock catch according to the OPEN direction in the above meter structure
diagram, unscrew the flexible coil lock catch, clamp the measured wire with flexible coil clamp, and
then rotate the lock catch as to the CLOSE direction, to lock the flexible coil again.
5.2.3. Observe the reading value, if the meter display "OL" symbol, indicate the measured
current exceeds the upper limit of the meter. The tested wire should be in the central position of the
flexible coil as far as possible (near point A), not near the opening and closing point (area C). The
test error at the opening and closing point increases about twice or more, and the error near
position point B increases by about 1%..
5.2.4. When the measured current is small, the test resolution can be improved by repeatedly
wrapping the flexible coil around to the measured wire for many times and then closing. For
example, the measured current is 10A, and the flexible coil wrapped around the tested wire for 3
times, the meter will show 30A, and the flexible coil will show 50A if it is wrapped around 5 times,
and so on, the actual current is equal to the display value of the meter divided to the number of
winding of the flexible coil.
