1. ZERO POINT ADJUSTMENT
IMPORTANT
1. Do not turn off the power to the transmitter
immediately after completion of the change in
the LRV (and/or URV) setting(s). Note that
powering off within thirty seconds after setting
will ca use a return to the previous settings.
2. Changing LRV automatically changes URV to
the following value.
URV ϭ previous URV ϩ (new LRV Ϫ previous LRV)
3. If the range-setting push-button and external
zero-adjustment screw are not touched during
a range-change operation, the transmitter
automatically switches back to the normal
operation mode.
