n Configure sensor
From among the sensor types displayed on this screen, select an appropriate electrode for the
sensor used. The measurement units can also be selected from among “/cm” and “/m”.
The cell constant (factory default) is determined by factory calibration made during
manufacturing.
The cell constant is indicated on the sensor. If a new sensor is used, the cell constant indicated
here should be changed. When this value is changed, the real cell constant will also be changed.
For details, see section 7.1.2.
n Temperature settings
Select a suitable temperature element from among those displayed and set it up.
Celsius (ºC) or Fahrenheit (ºF) temperature scale can be selected.
For details, see section 7.1.3.
n mA (output)
Select an appropriate process parameter from among those displayed and set it. The mA output
has been set to 0 – 500 µS/cm or 0 to 20 Ω cm at factory shipment. If a high resolution is required
in a consistent measurement process, set this parameter to a value suitable for the process.
For details, see section 7.2.
