5.2
Calibration
The calibration of the mA output may be done such that its span will be either proportional or
inversely proportional to the material level.
Note
The 4 and 20 mA levels may be calibrated in any order.
Proportional span
Inversely proportional span
high level = 20 mA
high level = 4 mA
low level = 4 mA
low level = 20 mA
5.3
Calibration: reference method
1.
Adjust the material level (or target) to the desired distance from the sensor face.
2.
Press the “4” or “20” key (as appropriate) to view the stored distance associated with that mA
output value.
3.
Press the key a second time to set the new distance reference.
4.
After viewing or calibrating, the unit operation automatically reverts to the Run mode (6 sec).
The calibration value is referenced from the face of SITRANS LU180 sensor, in the units
displayed.
