AC Voltage Measurement
1. Plug the red test lead into the "V Ω mA" jack and
the black lead into the "COM" jack.
2. Set the RANGE switch to the desired ACV position.
3. Connect the test leads to the device or circuit being
measured.
4. Turn on the power of the device or circuit being
measured. The voltage value will appear on the
digital display.
DC Current Measurement
1. Plug the red test lead into the "V Ω mA" jack and
the black test lead into the "COM" jack (for
measurements between 200mA and 10A, connect
the red test lead to the "10A" jack. Make sure that
the test leads are pushed all the way into the jack).
2. Set the RANGE switch to the desired DCA position.
3. Open the circuit to be measured and connect the
test leads IN SERIES with the load in which current
is to be measured.
4. Read the current value on the digital display.
