Thanks for that, I thought someone had once said that would work, but until I
know it better I have been trying to change it as little as possible.

MK,
All you need to do is unplug the jones plug where the key wiring goes to
the circuit board. No need to do any wiring!

MK,
Where are you? If you can't get a key made, I can probably send you one.
IIRC, you can 'activate' the key by removing a wire from the key switch.
That places it in 'CAL' mode. The schematic easily demonstrates this. I
don't think it was 'shorting' the two switch wires. Of course that requires
you to remove the top of the meter.

I just noticed a gotcha, I need to set the key to calibrate before I may
issue those commands, I guess I need a key. I have printed off the photo and
measurements someone on this board did, now to get to a key shop...

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).

David Partridge

Hi David,
well it is currently working and close to calibrated as far as I can tell.
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.
