Remote Operations
This section describes methods to operate the Calibrator by remote control.
XW Warning
The Calibrator can produce voltages up to 1020 V rms. Program the Calibrator with
caution to prevent the production of hazardous voltages without sufficient warning to
the operator.
Write programs carefully and test them extensively to ensure safe operation of the
Calibrator. Fluke Calibration recommends that you include routines to catch errors in
your programs. These routines help to identify programming errors that can cause the
Calibrator to behave other than intended. Set the Service Request Enable (SRQ)
register to program the Calibrator to cause an SRQ when it detects an error. The
skeleton program below includes error-catching code:
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 5560A in standby
1070 STOP
Operate the Product by direct local control from the front panel or by remote control from an instrument
controller, computer, or terminal. Remote control can be interactive, with each step controlled by the
user from a terminal, or can be set up to run automatically, taking commands from a computer within
an automated system. This section explains how to connect, configure, and operate the Product in
remote mode.
The remote interfaces use device-dependent commands to duplicate the functions of the front-panel
controls.The Calibrator has four remote interfaces: IEEE-488, RS-232 Serial, 10/100/1000-baseT
Ethernet, and USBTMC. All of the remote interfaces may be used simultaneously.
Note
Dual output and Inductance and 52120-related commands are not available in the 5540A.
