Sensor - Parameter
38
Go to device SAC254 Sensor > function Sensor > tab Parameter .
Select Sensor .
Select the sensor type from the drop-down list: For the MS08, select SAC .
After changing the sensor type, the device has to be restarted.
The device restarts with the selected sensor type.
9.2 Set the interval for the automatic measurements
The parameter Measure interval stores the interval for the automatic measurements.
The valid range is 10 s to 86400 s (i.e. 1 day).
The default unit for the measure interval is seconds (s). However, the measure interval can also be entered
in days (d), hours (h), minutes (m), milliseconds (ms), microseconds (µs), or nanoseconds (ns).

Go to device SAC254 Sensor > function Sensor > tab Parameter .
Select Measure interval and enter a value.
Validate with Apply .
The value is set.
9.3 Adjust the measure values (customer calibration)
The parameters at Measure values make it possible to adjust the manufacturer calibration and configure a
customer calibration.
The customer calibration supplements the manufacturer calibration. The manufacturer calibration values are
not changed by the customer calibration. Customer calibration can be used as a fine adjustment of the
sensor for special media and is not intended to replace the manufacturer calibration.
To configure the customer calibration, 2 constants will be needed:
▪ the scaling factor or slope (default: 1)
▪ the offset (default: 0)
The calculation of the offset and the slope is explained below.
To set a customer calibration, do the following procedure:

To set the offset, select Offset and enter a value. Validate with Apply .
To set the slope, select Slope and enter a value. Validate with Apply .
To name the adjusted value, select Name and enter a name. Validate with Apply .
Repeat for any value you want to adjust.
