SETTING DIP SWITCH 3
(LASER POWER CONTROL) SETTING DIP SWITCH 4
(AUTO ZERO)
AUTO ZERO setting lock
DIP switch 4 is factory-set to FREE. In this mode, AUTO ZERO can be
performed by either using the key on the controller panel or short
circuiting the terminals.
To prevent the output voltage from being mistakenly reset to zero, disable
AUTO ZERO by setting the switch to LOCK (bottom setting).
Note:
• The SHIFT adjustment trimmer on the controller panel functions only
when the switch is set to LOCK.
• When AUTO ZERO is used with the DIP switch set to FREE and then
the switch is switched to LOCK, the AUTO ZERO setting becomes
invalid and the AUTO ZERO function is disabled.
Caution:
After DIP switch 4 has been switched between FREE and LOCK, be
sure to turn the power supply OFF once and then ON again.
Laser power control
When the DIP switch is set to AUTO (bottom setting), emitted laser beam
quantity is automatically controlled according to the reflectivity of the
target. The switch is factory-set to MAX.
The AUTO mode is especially effective for measuring metal targets or
targets of a mottled material.
