I'm looking at an HP 3458A that boots up with a failure -- message is
OVLD. Running the self test the first time returned the following:
ERRSTR 209, "HARDWARE FAILURE -- INTERNAL OVERLOAD: 72"
I turned it off, waited a bit, turned it back on and got:
ERRSTR 202, "HARDWARE FAILURE -- SLAVE TEST: OVERLOAD"
A while later, powered up and got the original 209 error again. There
are no further errors behind these two, just them. The Assembly Level
Repair Manual has some error codes, but no details -- it appears to be
a fault in the DC measurement section. Anybody seen either of these
errors before, or have any idea what's wrong? Any and all help
appreciated. The power supplies appear to be working correctly.
