This procedure shows the setup and lists the steps to examine the MeaĆ
sured Voltage Supply and to check and adjust the Voltage Reference and
the Regulator Reference (see Figures 5Ć1, 5Ć2, and 5Ć3).
This procedure should only be performed if the instrument is out of
measurement limits and maintenance is required. If the CSA 803C is
already within limits, proceed to the Display adjustment procedure.
Measurement Limits
The measurement limits for this procedure are as follows:
Measured Voltage Supply limits must be 4.85 V and +5.25 V
Voltage Reference must be 5.15 V and +5.25 V
Regulator Reference must be 9.95 V and +10.05 V
