Warning
To prevent hazardous voltages from being produced without
sufficient warning to the operator, the 5820A Calibrator must be
programmed with caution. The Calibrator can produce voltages
up to 130 V.
Programs should be written carefully and tested extensively to
ensure safe operation of the 5820A 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 5820A 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 5820A in
standby
1070 STOP
