Thermal3 Command
(requires ENG access)
ldd zero

Description Zero the laser diode sensor by acquiring 128 laser diode sensor samples with the focus laser and the write laser off. The average sample is subtracted from the laser diode sensor samples to compensate for sensor and amplifier offsets when calculating various intermediates values. The focus laser and the write laser must be off to ensure that leakage from the focus laser or the write laser does not affect the calculations.

Note that the laser diode sensor is automatically zeroed during initialization.

Notes Thermal 1.0 / 1.7x equivalents:
