Warning
The 5500A Calibrator can produce voltages up to 1000 V rms
and must be programmed with caution to prevent hazardous
voltages from being produced without sufficient warning to the
operator.
Programs should be written carefully and tested extensively to
ensure safe operation of the 5500A Calibrator. Fluke suggests
that you include error catching routines in your programs.
These error catching routines will assist in detecting
programming errors that could result in the instrument
behaving differently to your intention. By setting the Service
Request Enable (SRQ) register, described in paragraph 5-60,
the 5500A Calibrator can be programmed to cause an SRQ
when an error is detected. The following program example
shows a skeleton program including error catching:
10 PRINT @4, “*CLS” ! Clear status
20 PRINT @4, “*SRE 8” ! Set SRE Error Available
30 ON SRQ GOTO 1000 ! Enable SRQ Function
100 ! Place body of program here
900 STOP ! End of program
1000 REM Start of SRQ Handler ! Start routine
1010 PRINT @4, “FAULT?” ! Request fault code
1020 INPUT @4, A% ! Input fault code
1030 PRINT @4, “EXPLAIN? ”;A% ! Request fault text
1040 INPUT @4, A$ ! Input fault text
1050 PRINT “Fault ”;A$“ detected” ! Print message
1060 PRINT @4, “STBY” ! Place 5500A in standby
1070 STOP
