4. Read the voltage on the scale. If the voltage is within a lower
range, the switch may be set for a lower range to obtain a
more accurate reading.
4.2. Measuring AC voltages
1. Connect the black test lead into the COM-jack and the red
test leads into the V/ jack.
2. Set the range switch for any of the AC V range positions
desired. When in doubt as to which range to use, always
start with the highest voltage range as a protection to the
instrument.
3. Turn power on in the circuit to be tested. Read the voltage
on the scale.
4.3. Measuring Resistances
When DC resistances are measured, the internal batteries furnish
power for the measuring circuit. Correction for battery deterioration
over long periods of time is provided by means of the Zero Adjust
control which is part of the ohmmeter circuit.
1. Set the range switch at the desired resistance range position
2. Connect the black test lead in the COM-jack, and the red
test lead in the V/ jack.
3. Connect the contact ends of the test leads together.
4. Observe the instrument indication. It should read "0" on the
OHMS arc. which is at the top of the dial.
5. If the pointer does not read "0", rotate the ZERO OHMS
knob at the right on the front panel until it does. If the pointer
cannot be brought up to the "0" mark, the appropriate battery
should be replaced.
