New (to me) HP 3421A DA/C Unit, some questions

[4ster]

I'll look at that carefully Garth.

As part of familiarizing myself with the new equipment I've used the DAC module's subroutines to sample my K-type thermocouples. The DAC uses T-type thermocouples in the Front Panel program. I've not tried the data logging program yet, it looks flexible.

Here is a trivial program for K-type thermocouples:

01 LBL "K-TEMP"
02 SF 21
03 "CHANNEL?"
04 PROMPT
05 ENTER^
06 LBL 00
07 FIX 0
08 ACX
09 FMT
10 FIX 1
11 XROM "TEMKX"
12 FS? 01
13 C-F
14 CLA
15 ARCL X
16 "> DEG "
17 FC? 01
18 ">C"
19 FS? 01
20 ">F"
21 ACA
22 PRBUF
23 RDN
24 FS? 00
25 GTO 00
26 END

It uses the TEMKX and C-F sub-routines from the DAC module. Set flag 0 to run an endless loop on one channel. Flag 1 converts to Fahrenheit.
