PERFORMANCE CHECK PROCEDURE
This procedure is used to verify proper operation of the option and may be used to determine the need for adjustment.
This check may also be used as an acceptance test and as a preliminary troubleshooting aid. Perform all steps, both in the
sequence presented and in their entirety, to ensure that control settings are correct for the following step.
PREPARATION
Removing the wrap-around cover is not necessary to
perform this procedure. All checks are made using
operator-accessible controls and connectors.
Turn on the instrument and ensure that no error mes-
sage is displayed on the CRT. If the instrument displays
"DIAGNSTIC. PUSH A/B TRIG TO EXIT" at power on,
one of the power-up tests has failed. If the error message
on the bottom line of the CRT is "TEST 04 FAIL XX"
where XX is XI, 1 X, or 11, the stored calibration data is in
error and the instrument should be recalibrated by a
qualified service technician before performing the
"Performance Check Procedure." If any other error mes-
sages occur, the failure is probably not related to
calibration and the instrument should be repaired by a
qualified service technician before performing either
procedure.
BMM OPTION CHECKS
1. Check Dc Volts Accuracy
a. Connect the calibrator via a BNC-female-to-dual
banana adaptor, a 50-Q cable, and a BNC-female-to-dual
banana adaptor to the HIGH and LOW DMM
input connectors.
b. Select the DC V function.
c. CHECK-Reading is within the limits shown in
Table 4-1 6 for each dc calibrator output voltage.
