Measurement of AC and DC current (500mA, 10A)
Warning!
• To avoid electricity shock, never perform AC current measurement for circuit with a voltage of
AC 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 the banana plug of the red test line
into the positive 500mA 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 F3 button to switch to DC, AC, Hz, % measuring mode.
4. Add the test lead in series with the circuit to be tested. The instrument will display the value of current, decimal
point and polarity.
The option menu of current measurement is as follows:
Relative value mode
Peak value holding mode
