Connect
SR1 10M standard in series with the DB 62. To minimize the effect of noise, make physical contact with the DM 5010 chassis
ground terminal.
5.
Adjust the ACV
Offsets
a. Turn off the power module, remove the DM 5010, and
connect
the DM 5010 rear-interface connectors to the pow
er
module
via the flexible extender cables. Turn
on the
pow
er
module.
b. Connect a shorting plug between the HIGH and LOW
input
connectors.
c. Set the DM 5010 controls to the preliminary settings
with the following exceptions:
ACV
+ DCV
on
d. Set the DM
501A to measure 200 mV de.
e. Connect the DM 501A low connector to the DM 5010
Lo test
point (TP1701) and the high connector to
the
DM 5010
Atten Out test point (TP1503).
Refer to Fig. 10-1
for
test
point
locations.
f. ADJUST—the
Atten Offset (R1601), using an insulat
ed adjustment tool, for a DM 501A reading of 0 ±0.05 mV.
g. Move the DM 501A
high lead to the DM 5010 Amp
Out
test point (TP1201).
h. ADJUST—the Amp Offset (R1305)
for a DM501A
reading of
0 ±0.50 mV.
i.
Disconnect the DM 501A leads and remove the short
ing plug.
6.
Adjust ACV Gain
Calibration Factors
a. Set the DM 5010 controls to the preliminary settings
with
the
following exception:
ACV
+
DCV
on
b. Connect the ac calibrator to the DM 5010 HIGH and
LOW
input
connectors.
c.
Set
the 200 Hz ac
calibrator output to the
voltage list
ed
in the table.
d. Press ENTER.
