Here is the current setup using stunt doubles for the FX, PX and resistors.
I’m glad that I started the setup and practice logging in advance of receiving the reference standards. Despite having GPIB logging running on another computer it still took some fussing to get it running on a different laptop.
I also learned some lessons that were not obvious (at least to me) in advance:
- Turn off energy saving on the computer so that it doesn’t stop logging.
- Don’t close the lid on a laptop
- Don’t turn off the master lab power (this is a safety habit; I taped over the switch so I would stop turning it off).
My current plan is to log 3 different setups. All 3 setups will log:
- Time
- Ambient Temperature
- Humidity
- Barometric pressure
- HPAK 34970A measuring
- Temperature near the references
- Voltage of PX
- Voltage of FX
Setup 1:
- HPAK 34401A measuring 1k resistor (all resistance measurements will be 4-wire)
- Datron 1081 measuring 10k resistor
Setup 2:
- HPAK 34401A measuring 10k resistor
- Datron 1081 measuring 1k resistor
Setup 3:
- HPAK 34401A measuring FX
- Datron 1081 measuring FX
- HPAK 34970A measuring (in addition to the above):
I plan to run setup 1 for 24 hours, setup 2 for 24 hours, and setup 3 for 7 days. There are, of course, much more that could be measured but I want to keep the standards for about 10 days and get it moving to the next member.
