Section 5-213 Service
PERFORMANCE CHECK
This section contains a procedure for checking instrument performance without removing the cabinet or making internal ad-
justments (external operators adjustments are made as needed). Only the performance essential to measurement accuracy
and correct operation are checked. The procedure is also useful as an aid in troubleshooting and preventive maintenance.
To aid in locating a step in the Performance Check procedure, an index is provided preceding the procedure.
EQUIPMENT REQUIRED
The equipment required to accomplish the performance
check procedure is listed in Table 6-1. The comments in
the Equipment Required portion of Section 6 and the foot-
notes for Table 6-1 also apply to the performance check
procedure.
EQUIPMENT PREPARATION
Refer to Equipment Preparation in Section 6, except do not
remove the equipment cabinet.
Control settings precede each major function to be perfor-
mance checked. Titles for controls are fully capitalized in
the procedure (e.g. INTENSITY).
