This menu allows the adjustment / assignment of the
measurement value and the scaling of the analogue
output.
Selection of the measurement value by selecting the
appropriate measured value key in this example, “DP °
C" for dew point °Ctd.
In text fields "4mA" and "20mA" the appropriate
scaling values are entered, here from
-80° Ctd (4mA) to -20° Ctd (20mA).
With "Error Val" is determined what is the output in
case of error at the analog output.
• <3.6 Sensor error / System error
• 22 Sensor error / System error
• 4..20 Output according Namur (3.8mA – 20.5 mA)
< 4mA to 3.8 mA Measuring range under range
>20mA to 20.5 mA Measuring range exceeding
