5.2.Sensor adjustment and scaling
These two quantities offer two different conversion rates and thus also different measuring
ranges and resolutions. It is important to strictly adhere to each of the maximum final valu-
es including the decimal point.
For the purpose of zero adjustment the 'ZERO' key is provided.
For configuring the sensor's individual gain and scaling there are two possible procedures.
1. If the sensor was supplied with a specific 'characteristic value ' in mV / V, this can
easily be entered in the sensor menu; scaling will then be performed with the final
value and decimal point.
2. Or, alternatively, the indicator can be deleted and the sensor can be subjected to a
force equivalent to the final value. Scaling will then be performed, similarly,
using the final value and the decimal point. Pressing the 'ADJ' key will adjust the
gain accordingly.
For taring purposes the standard function for 'zero-setting' the measured value is available.
