5-63. Ohms Remote Program Modifications for 5100B Emulation
The following example programs illustrate the conversions that are required for running a
5100B resistance program on a 5700A/5720A Series II in 5100B emulation mode.
Without these modifications, the 5700A/5720A Series II will still operate as a 5100B
emulator, but the resistance accuracy is only the 5700A/5720A Series II tolerance to
nominal, which is less accurate than a 5100B.
The shaded lines in these 5100B resistance programs are those that need to be modified
in order for the programs to run on a 5700A/5720A Series II in 5100B emulation mode.
5 REM ORIGINAL 51ØØB PROGRAM
1Ø REM THIS PROGRAM SETS THE 51ØØB TO 1Ø KQ, READS THE VALUE OF A
2Ø REM FLUKE 85Ø5A DMM AND CALCULATES THE ERROR.
3Ø RF = 1ØØØØ.Ø
4Ø INIT PORT Ø ! CLEAR THE INTERFACE (SENDS DCL)
5Ø CLEAR PORT Ø ! SET THE 57ØØA TO ITS POWER-UP STATE
6Ø PRINT @1,”ZTØ” ! SET 85Ø5 TO OHMS EXT TRIGGER
7Ø PRINT @4, RF;”Z,N” ! SET THE 51ØØB TO 1ØKQ, OPERATE
8Ø WAIT 2ØØØ ! WAIT FOR OUTPUT TO SETTLE
9Ø PRINT @1, “?” \ INPUT @1,R ! TRIGGER AND READ THE 85Ø5A
1ØØ ER = ABS(RF-R)/RF * 1E6 ! COMPUTE ERROR IN PPM
11Ø PRINT “EXPECTED “;RF ! PRINT RESULTS
12Ø PRINT “MEASURED “;R ! “
13Ø PRINT “ERROR”;ER;”PPM” ! “
