•  To start auto calibration, press the Start calibration tab. The pump will start fuel transition 

from the storage tank into the fuel tank. The current state of the pump is displayed on the 

Auto calibration tab – Pump is turned off, Pump is turned on. If the calibration has not started, 

check the frequency output mode and ensure that the Auto calibration mode is selected on 

the Settings tab (see Fig.1);  

•  While calibration, calculated calibration points are added in the calibration table on the 

Auto calibration tab. Current readings of the TKLS sensor are displayed at the top of the 

table – current fuel level in liters, appropriate sensor readings in the form of ADC stages and 

frequency;

• 

The target-liters display fuel level achieving which starts next step of calibration; 

• 

The performance displays fuel volume transferred by the pump per a minute;

•  When the calibration is on, the status “Calibration” is displayed on the status bar (at the 

bottom of the window);

Fig.4.Calibration finished.

The calibration is totally managed by the TKLS sensor. It means that after starting the calibration 
the configuration tool can be closed and opened to read complete calibration data after finishing the 
calibration.  

i

NOTE

IMPORTANT

Calculated calibration table is stored in the sensor memory till the sensor power restart. That’s way it is 
not recommended to restart the sensor after finishing the calibration till the calibration data will be read 
from the sensor.  

•  To pause the calibration, press the 

Pause button. To cancel the calibration, 

press the Stop button (displayed instead of 

the Calibration button when the calibration 

is on);

•  As all calibration points have been 

calculated, the calibration finishes (Fig.4). 

After that the calibration table can be saved 

in  an  external  file  by  pressing  the  Save 

calibration button. The calibration table is 

saved in text file in the \Tare folder located 

in root directory of the configuration tool.
