A) Insert the black test lead into the “COM” input terminal and

red test lead into the “mA “input terminal. (Max 400mA), or
“10A” input terminal (Max 10A).

B) Rotate function switch to Current setting. Press “SELECT”

button to select the AC measurement mode. Then connect
the test lead to the tested circuit in serial, 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.
