Warning
The operating temperature must be 0ºC ~40ºC when measuring current.
Remark:
It may have 10 digits or less unstable or wrong digits, it will not affect measurement
result.
Hold the Meter tight, do now release. The Hall components are very sensitive not
only to the magnet but also to heat and machines reaction force. Any shock will
cause the changing in reading in the short time. Follow the below procedure to
measure current will be more precise:

Hold the Meter tight and press the lever to open the transformer jaw. Center
the conductor within the transformer jaws, then release the Meter slowly until
the transformer jaw is completely closed. Make sure the conductor to be tested
is placed at the center of the transformer jaw, otherwise it will cause +1.0%
deviation based on the stated accuracy.
