4.3 Calibration
Three types of calibration are provided, namely temperature calibration, adjustment of
conductivity zero point's compensation coefficient, and adjustment of cell constant
compensation coefficient.
Table 7 Calibration setting items
Note
Be sure to perform calibration after the power is turned ON for the first time.
Precautions
z Previous value hold is used for transmission output during the maintenance mode.
z Contact outputs are in the following states during the maintenance, depending on the
selected control target.
z OFF when the control target is set to non, Cond or Err.
z ON when the control target is set to Hold.
z FAIL when the control target is set to FAiL and a system error occurs.
Display Item Description Reference Remarks
Temperature calibration
For temperature calibration;
Set the deviation from the
sample temperature only.
