Current Constant

Refer to Figure 3-25. Use this screen to examine the cell zero constant
calculated from the most recent calibration check. The constant represents
the voltage generated by the cell when no difference exists between the
amount of O

2

on the reference and process sides of the cell. Press NEXT to

access the PREVIOUS SLOPE screen.

Previous Slope

Refer to Figure 3-26. Use this screen to examine the slope value stored from
the second to last calibration check. The slope is the amount of cell voltage
generated for a given O

2

value. For each calibration check, record the slope

over the life of the probe. Tracking the slope will indicate if the probe is
degrading. Press NEXT to access the PREVIOUS CONSTANT screen.
