Thanks for all of the assistance. I will initially use a separate power strip for similar parasitic AC loads. Firmware version is 3703.

I know that with the ovenized oscillator the power supply (and therefore fan) are always on.

Are there any key strokes to determine the software version, other than a check sum ? Hi Stan, Hold recall down as you press power-on to see the firmware version. It's a very nice counter. I use them all the time.

Re: [time-nuts] New Acquisition: HP-53132A
According to the manual (in several places): *It is normal operation for the fan in the Counter to continue to run after the Counter is* *placed in Standby mode. Power to the timebase is continuous to maintain long term* *measurement reliability, and the fan helps maintain timebase temperature stability.* perhaps a in-line AC switch?
