4.8.3b Pressure Compensation:
In the TMO2D, pressure (PRES) compensation is typically used only with a TMO2 oxygen transmitter. Pressure
compensation will correct the oxygen readings for any changes in atmospheric pressure. If you have selected pressure
compensation, you must enter both transducer data and pressure grid data.
The display will briefly show “Working . . .” before proceeding to the next question.
.
The display again shows “Working . . .” before returning to the start of the Gas Calibration? submenu.
4.8.3c Background Compensation:
Background gas compensation in the TMO2D is typically used with a TMO2 oxygen transmitter to correct the readings
for changes in background gas concentrations. If you have selected background compensation (BKGD), you must enter
background grid data.
Note:
Each curve must have AT LEAST TWO entered data points.
PRESSURE GRID ENTRY
# of Curves?[X]:
Use the numeric keys to enter the number of pressure curves, then press [YES] twice
to confirm the entry.
Curve # 1
mmHg [XXX.X]:
Use the numeric keys to enter the pressure in mmHg for the first curve, and press
[YES] twice. Repeat this process for the other curves.
PRESSURE GRID ENTRY
# of Points?[X]:
Use the numeric keys to enter the number of oxygen points per pressure curve, then
press [YES] twice to confirm the entry.
Point # 1

Enter Point? [[YES]] no
The display will show the data entered for Curve #1, and ask if you wish to enter a
point. Use the [NO] or arrow keys to scroll between choices, and press [YES] to
confirm either a [YES] or [NO] selection. (If you select [NO], the menu proceeds to
the next point entered.)
