Help needed with Fluke 8845A SCPI commands

[ledtester]

I'm trying to control a Fluke 8845A via the serial port, and I'm having trouble making sense of the documentation in this manual:

https://xdevs.com/doc/Fluke/8846A/8845a_8846a_programmersmanual.pdf

Some simple commands I've tried work like (see page 36):

*IDN?
DISP ON
DISP OFF
SYST:VERS?

but others don't, like:

SYST:TIME?
DISP ON:TEXT "Hello"

Are these not supported on the 8845A?

And then on page 38, the MEAS? command only works if I put the meter in Fluke45 mode.

And these examples of page 39 don't work in either the 8845 or Fluke45 mode:

MEAS:volt:ac? 10
MEAS:diod? ON

On page 31 FUNC "VOLT:AC" works, but FUNC "CAP" doesn't. (of course - the 8845A can't measure capacitance.)

I think I'm missing something basic here.

Ok - I think I've figured it out. What I was missing was putting the meter in remote control mode with SYST:REM.

Thanks for posting that update. I guess is
is because it also supports GPIB. With GPIB the GPIB controller will assert Remote ENable whenever you send a command. Apparently for RS-232 this is an explicit operation you need to do.
