Sensor Slope

Measured conductivity value.

Sensor slope value.

Use the

and

keys to adjust the sensor slope value within the range 0.200 to 5.000

until the measured conductivity value is correct.

Sensor Offset

Measured conductivity value.

Sensor offset value.

Use the

and

keys to adjust the sensor offset value within the range –20.00 to 20.00

until the measured conductivity value is correct.

Temperature Slope

Measured temperature value.

Temperature slope value.

Use the

and

keys to adjust the temperature slope value within the range 0.200 to

1.500 until the measured temperature value is correct.

Temperature Offset

Measured temperature value.

Temperature offset value.

Use the

and

keys to adjust the temperature offset value within the range –40.0 to

40.0°C (–40.0 to 104.0°F) until the measured temperature value is correct.
