(6) Depress the [HOLD] key to save
reading VL in memory.
The vertical constant is displayed
one second after both face-1 and
face-2 vertical angles are input.
(7) Depress the [HOLD] key.
The vertical angle compensation is
calculated as half the vertical
constant and saved in the memory.
The LCD reverts to the start-up display.
Other key entries besides the [HOLD] key are ignored during this
operation.
To cancel the vertical angle compensation input while in progress, turn
OFF the power.
During adjustment, if the
automatic vertical constant (AC)
exceeds ±6', a buzzer sounds for 1
second, the “OVER” warning will
appear on the display, and operation returns to Step (2).
The newly corrected constant will remain stored in memory even after
the power is switched OFF. All subsequent vertical angle
measurements will be corrected by the new AC.
AC: 0°01´20"
