Temperature Sensor
All ProSwap Loggers have a built-in temperature sensor on the bulkhead. Temperature compensation is critical for just about
every parameter. While the temperature sensor cannot be calibrated, it is important to periodically check the sensor performance
against an NIST certified thermometer.
To ensure optimal performance, it is important to keep the temperature sensor free of any deposits. Rinse the thermistor after each
use. If deposits have formed, use mild soapy water and a soft bristle cleaning brush. The sensor can be stored dry.
As you perform the following sensor calibrations, if they use a liquid calibration standard, make sure the thermistor is submerge.
The exception to this is the conductivity sensor, which has its own thermistor and does not rely on the ProSwap Logger
temperature sensor.
Sensors, Calibration, and Maintenance
Calibration Screen Layout
The calibration screen has the same basic layout for each parameter.
Calibration value: This is the value the sensor will be calibrated to. The
Yellow Line on the graph corresponds to this value.
Accept Calibration: Select this to calibrate the sensor to the calibration value.
Finish Calibration: This option is only available with multi-point calibrations (i.e.
pH, ISE, turbidity, PC, PE, and chlorophyll). Finishes the calibration by applying
previously accepted points.
Press ESC to Abort: Press the ESC key to leave the calibration. The sensor will not
be calibrated to any points. The last successful calibration will be used.
Last Calibrated: View the date and time of the last successful sensor calibration.
Actual Readings: This shows the current measurement value on the Run screen.
The White Line on the graph corresponds to this value. Observe the White Line to
ensure the measurement is stable before choosing Accept Calibration.
Post Cal Value: This is the same as the calibration value. This will be the
measurement value in the current solution after the calibration is finished.
