A calibration utility is supported in the software CD which is included in the
product package. The detailed calibration procedures and description can be
found in the utility. Users only need to run the software calibration utility and
follow the procedures. You will get the accurate measure data.
In normal condition, the PCI-9111 already calibrated by factor before it is
shipped out. So, users do not need to calibrate your PCI-9111 when you get it.
