Check De Common Mode
Rejection
a. Set the DM 5010 controls to the preliminary settings.
b. Connect the DM 5010 input connectors to the de volt
age calibrator as shown in Fig. 5-1 A.
c.
Set the
de voltage
calibrator output to
100 V.
d. CHECK—that the DM 5010 display reads «s3.16 mV.
g.
Set
the
de
voltage calibrator output to 100 V.
h. CHECK—that the DM 5010 display reads ^1.00 mV.
i.
Set the
de
voltage calibrator to a minimum output and
replace it with the ac voltage
calibrator and counter.
j. Set
the ac voltage calibrator output to 15 V rms at
60.2,
±0.02 Hz. Use the counter to verify the calibrator
frequency.
e. Set the calibrator to a minimum output.
f. Add a connection from the DM 5010
GUARD connec
tor
as
shown
in Fig, 5-1B.
k.
CHECK—that the absolute value
of the DM 5010 dis
play reads ^0.21
mV.
l.
Remove
the
connection to
the DM5010 GUARD
connector.
