Hello...

Received my 34470A one month plus ago but only started to use it 1~2 week ago.

I have just done a test. A Fluke 884X Short was installed on the front panel terminals. The meter has been powered up nearly 90 mins before the statistical data recording (image below) was initiated.

The calibration menu shows that the meter was calibrated in July 2018.

Is the reading is OK? Since "Auto Zero" is ON, I thought the reading should be (very close) to 000.00000.

Note: When the test was carried out, the (4m x 4m) room's aircond temperature setting was set to 18 degC, while the temperature shown on the calibration menu (besides Uptime) is around 24.1 degC.
TiN:
To get best accuracy you should use meter with same ambient temperature as what used during calibration (typically +23 °C).
I think your meter is fine, but to know for sure you need much more than just a short.

My 34470A shows almost 0 for this quick test
Here is a picture of a comparison on my instrument.

You should test again at about the same temperature as per calibration certificate

Thanks TiN and HighVoltage.

I do not have a thermometer to measure the room/ambient temperature now. I will get one soon. By the way, what is the temperature (the one keeps changing 24.0~24.2 degC) shown on the calibration menu of the meter? Is it the internal temperature of the meter?
