After energizing, the unit will initialize and operate. It reaches best thermocouple accuracy after a few minutes of warm-up. For greater accuracy Digivac offers a combination transducer/thermocouple gauge which offers 1% accuracy in Torr ranges. We also offer ¼% accurate capacitance manometer gauges. -

If the tube is replaced, the unit must be recalibrated. It is best if this is performed at Digivac. If field calibration is done, the zero and span adjustments are available on two potentiometers which are accessible by removing the front panel of the instrument. The zero is on the right and the span is on the left. -

▪ 50 torr (50,000 microns) or higher for dry mechanical and diaphragm pumps). ▪ Connect Voltmeter leads to "Com" and "Vac" pins. ▪ The voltage should be approximately .161 Volts dc. Make slight adjustments, if necessary, so the low end vacuum reading is correct. If the above readings cannot be attained, either the instrument, the gauge tube, or the cable is defective. -

Because these gauges are microprocessor controlled, it is possible to provide custom control features at surprisingly reasonable prices. The software is “burned” into the microprocessors, which are socketed and easily replaced by a user.
