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:
