Performance Check —DM 5010
2. Check Ac Voltage Accuracy
a. Set the DM 5010 front-panel controls to the prelimi­
nary control settings with the following exception:
ACV + DCV on
b. Connect the ac sinewave voltage calibrator to the
DM 5010 HIGH and LOW input connectors.
c. Set the ac voltage calibrator output to the voltage and
frequency listed in Table 5-3 or 5-4, depending on the ambi­
ent temperature.
e. Set the CONVERSION RATE (FAST button) as listed
in the next line of the table.
f. CHECK —that the DM 5010 display reads within the
limits for the frequencies and FUNCTIONS listed in the
table.
NOTE
For the W and 20 Hz checks, press the LOW FREQ
RESPONSE button to obtain a stable display. Re­
lease the button for the remaining frequency checks.
g. Repeat parts c through f for each remaining line of the
table. For the 200 and 700 V range checks, use the power
amplifier.
h. Set the ac voltage calibrator to a minimum output and
replace the ac calibrator with the de voltage calibrator.
i. Set the DM 5010 range and the FAST button as listed
in the first line of the table.
j. Set the de calibrator output to the first voltage listed in
the table.
k. Repeat parts d through f for each line of the table,
checking only the display limits for de input.
d. CHECK—that the DM 5010 display reads within the
display limits for the frequencies and FUNCTIONS listed in
the table (De input limits using ACV + DCV function are
checked later in this step.)
I. Set the de voltage calibrator to a minimum output and
remove all connections to the DM 5010.
