A) Insert the black test lead into the “COM” input terminal and
red test lead into the “ “input terminal. (Max 400mA),
or 10A input terminal (Max 10A).
B) Rotate function switch to Current. Press “SELECT” button to
select the AC measurement mode. Then connect the test
lead to the tested circuit in series, the tested current value
and the current polarity of the point where the red test lead
is contacted will be displayed on the screen simultaneously.
Caution:
1. If “OL” is displayed on LCD, it indicates the tested current
value has exceeded the present range limit, please select
higher range to complete the measurement.
2. The Max input value is 400mA or 10A. (Depending on the
terminal where the red test lead is contacted) The overrated
current will lead to fuse melt or even damage the meter.
