Pressure Calibration Screen
Figure 6-2. Pressure Calibration Screen - 1 of 3
In Figure 6-2, the temperature calibration group of
screens allows the user to change the pressure units
displayed on the screen as well as calibrate pressure
instruments.
Pressure units are specifi c to individual pressure instru-
ments. Changing the pressure display units for a trans-
ducer also converts all pressure setpoints related to that
transducer to the new selected units.
The following pressure units are available for display:
• PSIG (Pounds/square inch gage)
• PSIA (Pounds/square inch absolute)
• kPa[A] (Kilopascals absolute)
• kPa[G] (Kilopascals gage)
• kg/cm2[A] (Kilograms/square centimeter absolute)
• kg/cm2[G] (Kilograms/square centimeter gage)
• inHg (inches of mercury) – Vacuum is shown in inHg,
positive pressure is shown in PSIG
• inWC (gage)
• Bar[A] (absolute)
• Bar[G] (gage)
• Torr[A] (absolute)
• Torr[G] (gage)
