Voltage Measurements
Press [VDC] if you are measuring DC voltages,
[VAC] if you are measuring AC voltages.
Press the appropriate range key or press [AR]
to let the multimeter autorange.
Plug the red test lead into the VOLTS (red)
jack, and the black test lead into the COM
(black) jack.
Connect the test probes to the circuit being
measured.
The display is read directly for the measured
DC or AC voltage.
Resistance Measurements
Press the [KOHM] key.
Press the appropriate range key. (Note: .1X is
not a valid range for this measurement mode.)
Plug the red test lead into the A/KOHM
(green) jack, and the black test lead into the
COM (black) jack.
Connect the test probes to the resistance
being measured.
Read the calculator display directly for the
measured resistance.
Current Measurements
CAUTION: The fuse will blow if the current
14
flowing into the A/KOHM (green) terminal
exceeds 0.5A.
Press [ADC] to measure DC currents, and [AAC]
to measure AC currents.
The range will be automatically set to .1X,
the only valid range for current measurements.
Plug the red test lead into the A/KOHMS
(green) jack, and the black test lead into the
COM (black) jack.
Connect the test probes to the circuit being
measured.
Read the calculator display directly for the
measured current.
