CMG-3T

The five-stage process comprises locking the Z, N/S and E/W masses,

followed by longer periods tilting the N/S and E/W sensor base to their

end stops. During the latter two periods, the position of the N/S and E/

W masses will “flip” to one side.

The BUSY LED is lit during each stage, but goes out briefly between

stages, allowing you to follow the progress of the lock.

UNLOCK

This command unlocks the sensor masses and prepares the instrument

to begin operating.

If UNLOCK is activated when the masses are already unlocked, the

processor will lock them and attempt to unlock again. This is useful if

you suspect that the locking procedure has failed.
