Thermal3 Command
(requires ENG access)
bpd cal diffsensor

Description Calibrate the differential sensor using the PSD sensor. With the write laser on, acquire samples from the differential sensor and the PSD sensor as the piezo voltage is ramped from the minimum voltage to the maximum voltage and then from the maximum voltage to the minimum voltage. The position samples of the differential sensor can then be compared to the position samples of the PSD sensor to calibrate the differential sensor. Note that the PSD sensor is inherently calibrated.

Note that this monitor command automatically calibrates the NVS parameters bpd psdoffset and bpd diffcal.
