Zero carryover test setup.
(b) With the thermistor mount connected to the test instrument, allow
15 minutes for warmup.
The coarse zero control can be adjusted for a zero
indication on test instrument meter.
(c) The test instrument meter should indicate zero when the fine zero
switch is pressed on Range switch is in position 1.
(d) With the coarse zero control adjust for a 0.9 milliwatt meter
indication.
(e) With a digital voltmeter connected
to
vrf
and
vcomp
center
conductors record the digital voltmeter as V1.
(f) Measure and record the voltage between the vrf center conductor
and ground.
(g) Measure and record the voltage between the Vcomp center conductor
and ground.
(h) The power can be calculated
by
substituting
the
recorded
indications in the following formula:
