Chapter 3. Calibration Procedure
3.1
INTRODUCTION
In order to increase the accuracy of the output voltage setting, output voltage
measurement and output current reading, a calibration procedure must be performed.
It is recommended to use the Microchip dedicated PMBMonitor GUI that can be
downloaded from the board’s web page, as it performs all needed computations and
greatly simplifies the procedures.
For more information on the mathematical basis and implementation of the calibration
procedures, refer to the
Appendix C. “Calibration Example”
.

main panels used in the calibration procedures described in this chapter.
For more information on the Installation and Operation of the PMBMonitor GUI, refer to
the
“PMBus™ Monitoring Graphical User Interface User’s Guide”
