Todd, the battery is already on my list of to do items. The security seal on the meter I've got on the way appears to have not been broken. I assume this is from the last cal back in 98. The fact that it has a seal on the case might be a sign that someone had done work internally, perhaps just the offsets.
I have two options, check the battery and replace as needed when I get the meter or wait until just before sending it off for cal knowing that if I loose the cal data it's not the end of the world. I assume Agilent isn't going to charge more because the cal data was lost? I think either way I need to know what the voltage is of the battery and what type of battery it is. Replacement of course would be done with a current limited power source in place to act as the battery while it's being changed. A bench supply with the voltage matched should do the trick. I'm hoping it will already have the 3.4v battery to make my life a bit easier. Not that I mind replacing a couple resistors.
Thanks,
Jeff
Why not just apply AC power while changing the battery. Just use an ungrounded soldering iron.
Or is there some other thing I am not thinking about?
