3458A ACAL 0

[klaus11]

A little help, when executing ACAL 0 does not execute, executes ACAL (simple). I have checked it manually and through GPIB.

In posts like this one error code or exact description of unit behaviour is a must .

My Palantir says you have calibration security activated on the box. Read the manual for commands SECURE and CAL

Edit: What you trying to do however? There is no specific ACAL 0.

I have tested:
3458A: OPT 1; OPT 2
FW: 9.1 fresh update ;  Docs / xDevs
NVRam ALL: Fresh but keep data (may be the problem)
Test> Pass
Error Display: None
Acal: Pass without errors and without asking for security code
ACAL 0: Does not execute correctly, Manual Calibration picks up CAL 0 to correct offset.
Initial precision: It takes away my dream. 

I am going to test security code and delete memories physically (it is meant not delete Cal data)

Security code is not the problem, I have touched a bit and blocked and will not let ACAL 0. I will clean NVRam, even though my eyes are heading to the FW.

I still don't get it.

ACAL 0 is same as ACAL ALL, meaning to run autocal for all functions. It's fully equivalent to running just ACAL without any parameters.

Try to rephrase it, What are you trying to get as result? Zero calibration is executed by CAL 0 and 4W low-thermal short at the inputs , not ACAL 0. CAL 0 required to execute separately at front and rear terminals.
This function did not change external behavior in firmwares since Rev5. I tested myself on Rev5, Rev7, Rev8 and Rev9.

Yes, I am a stupid CAL 0   , a video from YouTube confused me

Thank you TiN. Again a great help.
