Calibrate the Sensors
Follow these steps to calibrate the sensors.
1. Apply a known signal to the sensor.
2. In the Calibration Record dialog box, enter the applied value in the
Applied box.
3. In the Engineering Hi box, enter the upper limit of the value range for
this sensor.
4. In the Engineering Lo box, enter the lower limit of the value range for
this sensor.
5. Wait until the measured value is stable, and then click Record.
This records the group of data and the system will calculate the
deviation of the applied value against the measured value.
The deviation is calculated as follows:
Deviation = (measured-applied)/(Engineering Hi-Engineering
Lo)*100%
6. You may repeat this process.
IMPORTANT
When calibrating a pulse signal, the forced pulse value must
be set to the pulse number per second. In addition, the
measured value and the field applied value should also be
the total number of pulses.
