Note:
1. If the value of the voltage or current to be measured is unknown,
always start with the highest range to avoid overloading the
tester. The range selector switch should not be rotated while
under load.
2. The life and reliability of the tester will be greatly increased if test
leads are removed from the circuit before changing ranges.
3. Before making any measurements, check to see that the pointer
indicates zero. If the pointer is off zero, make the required
correction by turning the screw of the mechanical zero ADJ.
5.1. Measuring DC Voltages
1. Connect the black test lead into the COM-jack and the red test
lead into the V/Ω/mA jack.
2. Set the range switch for any of the DC volts 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. Connect the black test lead to the negative side of the circuit to
be measured and the red test lead to the positive side of the
circuit.
4. Turn the power on in the circuit to be tested. If the pointer
deflects to the left of zero, the actual circuit polarity is the reverse
of that anticipated.
5. Read the voltage on the black arc marked DC which is second
from the top of the dial. If the voltage is within a lower range, the
switch may be set for a lower range to obtain a more accurate
reading.
