Tips for Capacitance Manometer operation:
  1. Avoid over pressurizing the gauge
  2. Maintain a stable ambient temperature
  3. Avoid vibration
  4. Avoid particulate contamination, or any contamination that may affect diaphragm motion
  5. Recalibrate frequently

4. Input/Output (W):
5. Accuracy (G):
6. Connector (Z):
* The Full Scale Range value is the maximum pressure for which the particular capacitance manometer has been calibrated. The sensor will measure from this pressure to four decades below this pressure. Example: A capacitance manometer with a Full Scale Range of 10 Torr will accurately display pressures from 10 Torr to 0.001 Torr.
