Calibration on the sensor

Calibration instructions:
0% or 100% for calibration can be carried out independent of each other. We recommend only calibrating at 0% if a high
degree of accuracy is desired.
Note: To use this function the "Zero & span cal. Function " field found under basic settings have to be on - default is off
Instruction for 0% calibration:
•
Connect the supply cable
•
Empty the vessel
•
Activate "R" for 5 seconds to activate calibration mode = Yellow LED is on (ON) during the 5 second activation and
turns off (OFF) when calibration mode is activated.
•
Activate "R" once = Yellow LED flash once. Afterwards, the green LED flashes to confirm calibration.
Instruction for 100% calibration:
•
Fill the vessel to 100%.
•
Activate "R" for 5 seconds to activate calibration mode = Yellow LED is on (ON) during the 5 second activation and
turns off (OFF) when calibration mode is activated.
•
Follow the instructions under "Configurations Instructions" regarding the installation of drivers in the program.
•
Activate "R" twice = Yellow LED flashes twice. Afterwards, the green LED flashes to confirm calibration.
