On the 5372A you input a 60 mV 10KHz sinewave and perform Test 25. The adjustment is also called Maximum Hysteresis It also tells you that you should replace the 3,6V NiCd backup-battery on the CPU board. It's a soldered in purple battery. It will set you back about 15 USD or so, but considering that it fails after maybe 20 years of life I think it is a small thing. Then, trimming it up is fairly simple. Once you done those two steps, you are all set for another 20 years or so. I've done this to both my private HP5372A (the one failure it had when I got it) and recently to the one at work. I recommend doing it. Very low complexity and risk if you know what end of the soldering iron is the hot one.

Just the 160 error usually means the battery was replaced, but the system was not recalibrated (or a glitch wiped the memory). Anyway, I always replace the battery. The battery is not a NiCad. It is a AA sized (Tadiran) lithium cell. Correct, I just recall incorrectly. I did not find the exact model, but a similar. When I replace it, I install a AA battery holder so the next guy does not have to worry about soldering. You can cut the leads to the cell at the battery and solder the holder (or new battery) to the nubs so you don't have worry about desoldering on a 4 layer board. Or, if you happen to a dozen or so fully equipped Pace PRC-2000 ($6000+ when new) rework stations in the spare bedroom, you can desolder the old cell from the board. BTW, if you happen to need a pretty much fully equipped Pace PRC-2000 rework station (it slices, it dices, it makes Julian fries)... contact me offline... as our British friends would say they really are a sweet piece of kit... Hmm Julian calender fries? Would be intersting to look at one of those...

As I recall it, the reason for lead limits on drinking water was kept high was the use of lead pipes in the UK.

It means the battery is dead. See the list archives. The battery is available from Tadiran / Mouser.
