Electric shock hazard.
Contact with live circuits can result in severe injury
or death.
Current Measurement
1. Shut off and lock out the power.
2. Open the branch of the circuit where the current is to be measured.
3. Plug the black test lead into the COM terminal.
4. Plug the red test lead into the
A
terminal (for current measurements up to 10 A) or the mA
terminal (for current measurements up to 400 mA).
5. Set the selector switch to the appropriate setting. Press the function (blue) button to select
AC or DC current (the AC icon or the DC icon will appear).
6. Connect the test leads to the circuit.
7. Apply power to the circuit and read the display.
Notes:
• If the resolution of the reading is not satisfactory, shut off power to the circuit and
switch to the next lower range. Turn on the power to the circuit and read the display.
Repeat this procedure until the resolution is satisfactory.
• For readings of less than 400 mA, plug the red test lead into the
mA
terminal.
8. Shut off power and disconnect the meter from the circuit.
Do not attempt to measure more than 10 amps. Electric shock can
result.
Do not change the position of the selector switch when the test leads are
connected to a component or circuit. Damage to the meter can result.
