Confirm calibration value
Press ‘ENT’ button on the remote control to
confirm self-calibration value. The Y
direction self-calibration indicator light
will extinguish after pressing this button.
Note: In order to make the calibration effective, you must power off the
instrument after the calibration, and then power it on again. Y-axis
accuracy check is a necessity after X-axis calibration, and X-axis
accuracy check is also a necessity after Y-axis calibration.
Instrument self-calibration will not be fulfilled until both X-axis and
Y-axis accuracy meet the requirement.
