Five analog sensors, an AC voltage sensor, two battery current sensors and two battery voltage sensors can be
calibrated by accessing this page. The Analog Input 1 is dedicated to the Pressure Transducer. The other Analog
Input depends on the controller options.
Every sensor, except the AC Voltage can be calibrated the same way. The Signal destination, the Unit type, the
Unit, the Min and Max values are variables that are set in factory but the calibration can be made in the field.
There are three ways of calibrating a sensor that can be chosen in the windows below "Sensor value".
-Sensor value: Connect an external measurement tool that is already calibrated (like a Manometer to calibrate a
pressure sensor). Bring the system to calibrate to a low point. While looking at the measurement tool, press the
read button (the button with a circular arrow). The value that was displayed on the measurement tool when the read
button was pressed needs to be enter in the "Low" window below the Desired value. Repeat these steps with a high
value. Then press compute. For the PT1, only a high value is required.
-Theorical voltage: Use a graphic of the theorical sensor's voltage response (usually given in the datasheet of the
sensor). Enter a low point (value, voltage) and a high point. Then press compute.
-Theorical current: Same as the theorical voltage, but with amperes.
For better results, use two points that are far apart, but in the normal range of the sensor.
For the AC voltage, only one point is needed.
