3 CONFIGURATION 
Before you start 
This interface is calibrated by determining at which level the tank is full and at which level it is empty. 
The interface then calculates the tank level by interpolation. This min/max method of calibration only 
works for a linear tank, i.e. where all levels are equal. If your tank is non-linear, you need to calibrate 
manually. 
Linear: Non-linear: 
 
•Min/max calibration 
1. In MasterAdjust, select Min/Max from the Calibr.mechanism options. 
2. When the tank is empty, press the Tank empty button. 
3. When the tank is full, press the Tank full button. 
•Manual calibration 
1. In MasterAdjust, select Manual from the Calibr.mechanism options. 
2. Enter the data in the Value @ x% fields. This information either comes with the tank, or can be 
calculated, or can be determined by using the sensor information on the Monitoring tab while 
changing the tank content. 
Example situation: 
- resistive type sensor; 6 Ohm when empty, 186 Ohm when full. 
- tank volume = 1000 liter 
When the tank is empty and the sensor is on, add 50 liter. Check the sensor value on the 
Monitoring tab and enter this value in the Value % 5% field. Add another 50 liter, check the 
sensor value and enter this value in the Value % 10% field. And so on. 
The following table shows the Tanklevel Interface configuration items as displayed in MasterAdjust. 
Sensor fluctuations can be damped to 
different levels. The heavier the damping, 
the larger the fluctuations that are damped.
