OCCURRENT MEASUREMENTS
WARNING ~DO NOT APPLY VOLTAGE TO
MEASURI NG TERMINAL WH ILE RANGE SWITCH
IS IN CURRENT POSITION.
1. Plug the test leads into th e correct jacks.
2. Set the range switch to the 300m DCA position {300
milli ampl. Always start at the t op and work down.
3. Open up the circuit in which you want to measure the
current and connect the blélck lead to the negat ive side
and the red lead to the pos itive side of t he circuit .
4. Apply power to the circuit undcr test and read the
current on the black OC sca!es.
DE CIBEL MEASUREMENTS
1. Plug the test leads into the correct jacks.
2. Set the range switch to one of the ACV ranges.
3. For a range switch setting of 15 ACV, read dB directly
on the bottom scale in dB. For other senings of the
range switch, add the appropriate number of dB to
the dB scale reading 'as noted on the chart at the lm.ver
ri ght on the meter face.
Note: For absolute dB measurements, cir c uit impedance
must be
600 ohms . 0 dB = 1 milliwatt dissipated in a 600
ohm impedance (equivalent to 0.775 volts across 600
ohms).

OUT PU T VOLTAGE MEASUREMENTS
1. To measure AC voltage in the presence of OC voltage,
use the output fonction. Connect the black l ead to the
8 COM jack and the red l ead to the OUTPUT jack.
2. Set the range sw i tth to an ACV pos:ition and rneasure
t he voltage in the circuit.
Note : The output functîon î ncorporates a OC blocking
capacitor, rated at 600 vo lts. Do not exceed the 600 vo1t
rating
when measuring output voltages.
3.
Read output voltages on th e same scales as for AC
voltage.
