* Into a 55 ohm load. Output for all gauges at 0.1 mTorr is 10 mV. Gauge tubes fit Amphenol 78-PF8-11 or equal basing.
Notes
- All gauge tubes are individually calibrated and marked with the heater current required to provide 10 mV output. This is done across 55 ohms when the gauge is under vacuum and pressure is lower than 1 x 10-4 Torr.
- For the TG-6343/004M high tolerance tube the calibration settings are 9.6 mV at 16.4 mA.
