tance is a function of the applied voltage, which is
dramatically altered by the ohmmeter itself. Autoranging
ohmmeters are particularly unreliable.
Figure 5 shows a circuit that gives reliable results. This
circuit uses a 100mV voltage source and a low-voltage-
drop ammeter as the measuring circuit, and an
adjustable supply to sweep the analog voltage across
its entire range. The ammeter must have a voltage drop
of less than 1mV (up to the maximum test current) for
accurate results. A Keithley model 617 electrometer
has a suitable ammeter circuit, appropriate ranges, and
a built-in voltage source designed for this type of mea-
surement. Find the path resistance by setting the ana-
log voltage, measuring the current, and calculating the
path resistance. Repeat the procedure at each analog
and supply voltage.
Note that it is important to use a voltage source of
100mV or less. As shown in Figure 5, this voltage and
the VAIN voltage form the VAOUT voltage. Using higher
voltages could cause AOUT to go into a fault condition
prematurely.
