DMM7510 How can I read warm-up time via remote interface?

How can a remote program know that the device has warmed up enough? So that I can trust the measurements automatically. Maybe the device has frozen and someone restarted it 5 minutes ago and it has not warmed up yet.

Is there any command for this?

I can read the internal temperature. It becomes relevant after warm-up time. But it's very inconvenient.

Hi,
There is no direct command to read the warm up time. However according to the manual, an information event should be posted to the event log when the warm up time has completed. Therefore, you could read the event log to confirm the event was posted before proceeding. The event log is cleared on power off, so if the DMM were to lose power, you wouldn't read a previously existing event. 

It is very uncomfortable.

In my opinion, I can not read the log again? Or I'm wrong?

The event for warm up time is event number 2822. The message is "Warm up period complete." The eventlog.next() command returns the oldest event in the log, so you could return the event code: 

eventNumber, message, severity, nodeID, timeSeconds, timeNanoSeconds = eventlog.next()

And check if the eventNumber is equal to 2822 before proceeding. Once you've read the event remotely, it cannot be read again remotely as it's cleared from the queue, but it does still appear on the front panel. If you restart the DMM, the warmup timer would be restarted and a new warm up event would be generated then.
 

Thank you for your attention to my problem.

I go to my computer and run my script. I don't see the device. I only have remote access. I don't know if the script was run before me. But I want to know if the device is warmed up. If I read the log, it may have been erased by a previous run of the script.

Is there any other way to find out if the warm-up is complete?

I was considering reading the internal temperature. In my opinion, I can only read the temperature from a warm-up device. But this is also not very convenient because I can only read the temperature when measurements are in progress. It turns out to be a very difficult path..... :(

If the DMM will be left idle between runs, then yes, using the event log is not helpful. There's no other way to tell if the warm up period is directly complete. You can monitor the internal temperature separate from your measurements though. The DMM has a built in internal temperature sensor and command to return the value of the internal temperature. Please see attached screenshot from the manual. 

Is it possible to add a command to read the Warm_up_end flag?

Temperature reading doesn't work in Digitize mode :(
