DC Voltage Calibration*
* optional calibration requiring the use of a calibrated multimeter.
4.1
Review the Performance Requirements in Table 5-1.
Note
: Whenever the test requirement is not met, verify the results of each test and take corrective
action before proceeding.
4.1.1
Set-up the UUC as described in sections 3.2 and 3.3.
4.1.2
Turn on the multimeter and set it to DC Volts and auto-ranging.
4.1.3
Connect the positive and negative leads from the multimeter to the corresponding
terminals of the RS-201 decade box.
4.1.4
Set the UUC to 9V and adjust the decade box to 90 k
Ω
. Record the voltage displayed on
the multimeter to 2 decimal points (xx.xx).
4.1.5
Set the UUC to 67.5V, 80 k
Ω
and adjust the decade box to 80 k
Ω
. Record the voltage
displayed on the multimeter.
