Warning

The operating temperature must be 0 ~40 when measuring ℃℃

current.

Remark:

 If the reading is positive, the current direction is from bottom to

up. See figure 10, the front case face up while the bottom case

face down. 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:
