Check the current calibration coefficient. These coefficients are updated for each calibration. Figure
6.11 shows an example of checking the coefficient.

6.1.12 Displaying Software Revision “rEV”
This item is for checking the software revision of the OX400 and is not a setting.
Operation: Hold down the [MODE] key for 2 seconds, select “rEV” with the [▲], [▼] keys, and
press the [ENT] key.
The current software revision is displayed. Figure 6.13 shows a display example.
6.1.11 Displaying Cell Resistance Value “CEL.r”
This item is for checking the sensor state and is not a setting.
Operation: Hold down the [MODE] key for 2 seconds, select “CEL.r” with the [▲], [▼] keys,
and press the [ENT] key. The sensor cell resistance value is displayed. The unit is Ω. If the
value becomes larger than 1050 Ω, “oVER” appears.
NOTE
When the sensor is replaced, the cell resistance value is not displayed. It is displayed when calibration
of something other than air is performed.
