Front Page A – Default
There are 3 main front page displays for the CDP301: A, B & C.
When navigating the CDP301 user menu the following abbreviations will be observed:
• Tm = Current Mirror Temperature
• SP = Current mirror Set point temperature. When instrument is in AUTO
mode and when selected to do so, this value will change according to the
AUTO RATE. When instrument is MANUAL mode and when selected to do
so, this value will change according to the MANUAL STEP.
• Tdp = Calculated dew-point temperature (calculated average of Tf and Te)
• Tf = Formation temperature. The user-determined mirror temperature of
dew formation.
• Te = Evaporation temperature. The user-determined mirror temperature
of dew evaporation.
• Tb = Body temperature
• Pr = The sensor cell gas pressure (in user selected PRESSURE UNIT).
The status bar also contains the following information:
Mode: Water (WD) or Hydrocarbon (HCdp) Dew point measurement mode
• Auto (WD or HCdp); Automatic mirror temperature ramp in °C/min
• Manual (WD or HCdp); manual temperature increment in °C
