The 7510 doesn't either.

The Keysight meters (DMM) all do NOT have a standby mode!
The new ones do have a SW switch only, instead of a mechanical mains switch.
So even if the StandBy LED is lit, they are completely cold inside.

Interesting. The Keysight manual refers to it as standby mode. What is the point of doing it the way they do?

No benefit that I have found. Except the Keysight is showing a little yellow light, so you know the mains is plugged in.
Cold with unplugged mains or in standby, the boot-time and warmup-time does not make a difference on both instruments.
Boot-Times:
- Keithley DMM7510: 10 seconds
- Keysight 34470A: 19 seconds

Can someone make that warm up graph with 3458 please?

I am curious why warm-up and start-up time are important in your application? Or is it just a measure of general temperature sensitivity?
