Note
A Fluke 5520A or 5500A Calibrator is
recommended as a source for the voltage
method due to its output voltage/current
capabilities. A Fluke 8845A Digital
Multimeter (or equivalent) is
recommended for measurements with
either test method.
For the voltage test method, test each resistor as
follows:
1. Apply the recommended voltage at power
mains frequency (either 50 or 60 Hz)
between the terminal for the resistor being
measured and the COM terminal.
2. Measure the current flowing through the load.
3. Calculate the resistance by dividing the
sourced voltage by the measured current
(R
L
=V
s
/I
m
).
The calculated resistance should be within 10 %
of the nominal resistance value found in Table 1.
Repeat steps 1 through 3 for each Load resistor
terminal, adjusting the applied voltage per
Table 1.
For the alternative multimeter test method,
measure each resistor as follows:
1. Place the probes of a multimeter between the
selected resistor input terminal and the COM
terminal.
2. Read the measured resistor using the
resistance mode of the multimeter, and note
the value.
3. Insure the measured value is within 10 % of
the nominal resistance.
Repeat steps 1 through 3 for each Load resistor
terminal per Table 1.
