Next type 7 for Analog inputs
Choose 1 for Port 1 (mA) and the next screen will appear:
Assign a name to the sensor (option 1: Name)
1. Set the power switch to enabled and enter the warm-up time. (the power switch will supply the sensor
with 12 Volts, and will be activated the time you specify, before a measurement is taken)
2.
At default Set the sample interval to the ‘Data log interval’ so only one sample per data log interval
will be taken. You can set the sample interval to a specific value in case you want to record periodic
averages (e.g. a 10-minute wind direction, see chapter: Aggregation channels) or continues alarm
sampling.
3. Set the parameter name.
4. Set both minimum (option 6) and maximum (option 7) values of your sensor at 4mA and at 20mA. If
you don’t know those values, you could determine the scaling by measuring two calibration points
(option 8). Those calibration points don’t have to be at the sensors absolute minimum and maximum,
