5.3 Set Significant Digits?
The first option in the Factory Setup Menu, Set Significant Digits? , enables you to modify the resolution of the gas
reading on the TMO2D display, when you select display in PPM ranges. You can select values from 2 to 4; the default
setting of 3 suppresses one significant digit, a setting of 2 suppresses two digits, and a setting of 4 displays the full
resolution of the calculated gas reading. However, while the Significant Digits option affects the display, the analog
outputs retain full resolution at all times.
Note:
This option applies only if you select display in ppm ranges. If the TMO2D is set up for the 10 ppm range, it
defaults to 2-digit resolution. However, you can change the significant digits in this menu.
5.4 Select Background?
The Select Background? option enables you to select a background gas label if background compensation is active and
the LCD has been programmed to display the background gas.
Note:
Background compensation and display apply only for a TMO2 oxygen transmitter. If the Auto Calibration
mode is active, the TMO2D displays calibration status instead of the background gas.
