Basic setting
Sensor description:
Enter a sensor name.
Ch1 setting
Measure type:
Select mA or voltage etc.
Description:
Enter a sensor name.
Predefined unit:
Select a physical unit.
Customized unit:
Enter the unit as you want.
Resolution:
Select the precision for the channel (how
many digits are required behind the decimal point).
Lower limit / Upper limit:
Enter the lower and upper
limits of the measurement range.
One point calibration:
Enter the reference value for the
one-point calibration. Based on the reference value, the
S551 provides a one-point system calibration for the
channel. One-point calibration can eliminate the
measurement error of the connected sensor.
The calibration reference value will then be stored in the
S551, and applied to the sensor that is connected to this
channel. If you connect another sensor to this channel,
make sure to delete the previous reference value.
