The sensor input is factory set for Mode
Measuring range: 0...50.0 g/kg
Output signal: 0 - 10 V
Connection terminals: "E1", "GND", "24V"
Input for sensors with free measuring range and linear characteristic curve adjustable
for the following standard signals:
0 - 10 V, 0 - 20 mA, 4 - 20 mA
For sensors with free measuring range, the sensor measuring range must be entered
under the following menu points in order to ensure a correct actual value display: E1
unit, E1 decimal, E1 Min., E1 Max.
E1 Offset
Sensor calibration with calibrated comparison device.
The current "E1 Actual" is displayed including the offset set here.
