AC and DC current （400mA，10A）measurement
• To avoid electricity shock, never perform current measurement for circuit with a voltage of
250V or higher.
• When measuring large current with 10A gear, the measurement duration in every 15 minutes shall
not exceed 30 seconds. Otherwise, damage to the instrument and the connecting lines of test leads.
1. Plug the banana plug of the black test line into the negative" COM "socket and Insert the banana plug of the red
test lead into the positive "mAmF" or "10A" socket.
2. Rotate the rotary knob to select" " or " " function. Then, a sign of "CURRENT" will appear on the top
of the screen to remind user that the function of current measurement is currently available.
3. Press the F3 key（SEL）button to switch to DC, AC,measuring mode.
4. Put the test lead into the circuit. The instrument will display the digital of current, decimal point and polarity etc.
The option menu of current measurement is as follows:
a. Press the F1 key (REL) to enter the relative value mode.
b. Press the F2 key (P-H) to enter the peak hold mode.
c. Press the F3 key (SEL) to select extended functions: DC,AC.
