Calibration - ICP DAS USA PET-AR400 User Manual

8. Calibration

PET-AR400 is calibrated and the calibration parameters, including the gain value and offset value,
are stored in EEPROM when it is shipped. However, in certain extreme environments, more
accurate voltage measurement may be required. In this case, a visual manual calibration method is
provided.
Step 1 ： Prepare a high-precision signal generator and
download the calibration software
The precision of the signal generator is the higher the
better. The calibration tool can be obtained from:
https://www.icpdas.com/en/product/PET-AR400
Step 2：Connect the signal generator to the channel to be calibrated
Step 3：Set the output of the signal generator
Set the signal generator to output a 102.4 Hz, 20Vpp sine wave to the channel that needs
calibration.
