Fluke 5700A Series II - 5-1. Introduction

Remote Operation
Introduction 5

5-1. Introduction
The calibrator is capable of operating under remote control of an instrument controller,
computer, or terminal, as well as under direct local control from the front panel. Remote
control can be interactive, with the user controlling each step from a terminal, or can be
set up to run automatically, taking commands from a computer within an automated
system. This chapter tells you how to connect, configure, and operate the 5700A/5720A
Series II in remote mode.
The remote programmer uses a language of commands called “device-dependent
commands” to duplicate the functions of the front panel controls.
An alternative language capability is included for users of the Fluke Model 5100B. It lets
the 5700A/5720A Series II emulate a 5100B in response to commands and allows
substituting either one of these calibrators into a 5100B system with no, or in some cases
minor, software modifications.
Note
If you own a previous version of the 5700A calibrator, you can use its
remote programs to operate the 5700A/5720A Series II.
WWarning
The calibrator can produce voltages up to 1100V 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 calibrator. We suggest that you
include error-catching routines in your programs to ensure that
your instrument performs as you intended. By setting the
Service Request Enable register (SRE), described in paragraph
5-26, the calibrator can be programmed to cause an SRQ when
an error is detected.
The following example shows a skeleton program that includes
error-catching.
1Ø PRINT @4, “CLS” !Clear status
2Ø PRINT @4, “*sre 8” !Set SRE Error Available bit
3Ø ON SRE GOTO 1ØØØ !Enable controller SRQ function
1ØØ !Put body of program here
9ØØ STOP !Put body of program here
1ØØØ REM start of SRQ Handler
1Ø1Ø Print @4, “FAULT?” !Request fault code
1Ø2Ø Input @4, A%
1Ø3Ø Print @4, “EXPLAIN? “;A% !Get explanation of fault code
1Ø4Ø Input @4, A$
1Ø5Ø Print “Fault “;A$” detected” !Print message to programmer
1Ø6Ø Print @4, “STBY” !Set 57ØØA to standby
1Ø7Ø Stop
