ACA Measurements
1. Insert the black test lead into the COM terminal and the red one into
the mA terminal (maximum 400mA) or to the 20A terminal (maximum
20A)
2. Use the selector knob to set the proper ACA range, press the DC/AC
key to select the measurement mode, and then connect the leads in
series to the electric circuit under test. LCD displays current under test.
Note:
1. Users should first set the RANGE button to the highest range, if
users have no idea about the range of current under test, and then select
the proper range based on displaying value.
2. If the LCD displays OL, it means the current is over range. Now you
need to select the knob to the higher range.
3. Maximum input current is 400mA or 20A subject to the terminal the
red test lead is inserted into, too large a current will damage the fuse
and meter.
Resistance Measurements
1. Insert the black lest lead into the COM terminal and the red lead into
the V/Ω/Hz terminal.
2. Turn the selector knob to Ω range.
3. Connect the leads in parallel with the resistance being measured.
