4 Current measurement
Notes:
the meter is mainly used for ground resistance test and the current measurement
shall be only applicable to the current test on the ground wire but the power line
or affect the magnetic property of the clamp head and finally affect the ground
resistance test accuracy .
After power-on self check, clamp meter shall enter into the resistance
measurement mode. After display the OL ", press key A, clamp meter enter into
current measurement mode, displaying AC 0.00m as shown in picture 7.
Pull the trigger, open the clamp jaw and clamp on the wire to read the current
value.
OL on the clamp meter , it means the current being measured exceed the
upper limit of clamp meter, as shown in picture 8.
Flicker display symbol with sporadic beep--beep--beep-- , it means the
current being measured exceed the current alarm critical value.
