About sensor calibration
The sensor characteristics slowly shift over time and cause the sensor to lose accuracy. The sensor
must be calibrated regularly to maintain accuracy. The calibration frequency varies with the
application and is best determined by experience.
Temperature calibration
It is recommended to calibrate the temperature sensor once a year. Calibrate the temperature sensor
before calibrating the measurement sensor.
1. Measure the temperature of the water with an accurate thermometer or independent instrument.
2. Push the menu key and select SENSOR SETUP>CALIBRATE.

signal value for 60 seconds). The filter increases the time for the sensor signal to
respond to actual changes in the process.
Sets the time interval for data storage in the data log—5, 30 seconds, 1, 2, 5, 10,
