About Calibration
Although this product is calibrated before shipping, you can use the calibration program to calibrate
analog output yourself.
Starting the calibration program
Click the [Calibration] button on the property page for the device to start the calibration program.
*For module ID, the setting value of Module ID rotary switch is displayed.
Proceed with connecting the calibration equipment and performing the calibration in accordance
with the instructions displayed by the calibration program.
Analog output calibration
Analog output calibration requires a digital multimeter.
As the analog output has 16-bit resolution, use a multimeter with a precision of at least 5 digits after
the decimal point.
Calibrate each channel separately for each range that you use.
Factory setting
You can use the calibration program to restore the factory calibration settings.
If for some reason you are unable to achieve the rated accuracy, please contact your retailer.
