IX.Operation Instructions
Test wiring
Two test clamps are clamped to switch contacts or test ends.
I+/U+terminals are connected with red test lines, I-/U-terminals are
connected with black test lines, in which the thick-wire inserts are
connected with current terminal I+/I-, and the thin-wire rods are inserted into
voltage terminal U+/U-.
It is necessary to use the special low resistance test line matched with the
instrument, tighten the current connection pole, and firmly clamp the test
clamp to reduce the lead resistance and save the battery power.
If the test line contacts badly and the current cannot reach the set value, the
instrument will stop testing and alarm.
Test grounding
In live environment, it is necessary to ensure that one end of the sample
has been grounded.

automatically to save electricity; the instrument has low charge prompt
function and over-discharge protection function.
