If all you want is to save the calibration factors, just issue CALIBRATE,DUMP command
To refresh the EAROM calibration factors, issue CALIBRATE,REFRESH - barring component failure that should be good for another ten years or so. You can also display the NVM contents with the MONITOR command, but NOT re-write them. The only way that I am aware of that will write the caibration constants if they have been lost is to run a full calibration. Again all this in chapter 8. I don't know which ROM programmers that can read or write the ER3400 (just ignorance - there may be loads).

But I want to get those calibration factors saved before it dies on me. Last calibrated 2008, and well down on drift by now. I get a diurnal 0.14 microvolt drift with a shorting plug that stays on when not in use. a drift of about 0.1 microvolts in about 3 weeks. Nothing else to confirm anything else as I have only just got it chatting out through the rs232. I will have to buy something to read them with.
