Super User Temperature & Status Page
Depressing the “Zero” key will manually zero the detector.
Depressing the “Lamp” key will toggle the lamp on and off.
Depressing the “Edit” key will provide a new menu of options above the
keys to:
1. toggle the heaters on and off
2. change the heater set points
Super User Calibration Page
The calibration screen has the same appearance as in Normal User mode,
but you now have the option to modify the Rfactor and Concentration
Factor in addition to the Concentration (Conc). For this instrument the
Concentration Factor must be 1 for proper operation.
Concentration and Response Factor Calculation
RF = (AREA / (CONC x VsigAdj)) x Cal Ratio x 65535.0
GAS_CONC = (AREA / (RF x VsigAdj)) x 65535.0
RF = Response Factor
VsigAdj = Response Factor Adjustment due to RGD lamp intensity
CONC = Concentration (or blend) of Calibration Gas Cylinder in
ppb
VSIG = RGD detector analog voltage in A/D counts
Cal Ratio = 1 (Concentration Factor)
65535.0 = factor used to adjust software VsigAdj based on VSIG,
lamp intensity (VsigAdj = VSIG A/D counts x 2500 / 65535)
Super User Run Screen
The run screen in Super User mode is very different than the functionality
and appear ance of Normal User mode.
1. The top line provides current mode, current viewable time, current at-
tenuation, and current time respectively.
