5. ANGLE MEASUREMENT
5.1 Measuring an angle
Aim at the first target, then press [F3] [0 SET]
twice in succession to reset the
horizontal angle to 0.
Aim at the second target,
then read the horizontal angle.
Pressing [F4] [DISP] displays the vertical angle.
The [0 SET] key cannot reset the vertical angle to 0.
Pressing the [DISP] key cycles through the sets of display items:“H.angle/H.dst./V. dst.”,
“H angle/V.angle/S.dst.”, and “H.angle/V. angle/H.dst./S.dst./V.dst.”.
Even though you turn the power off during a survey, the horizontal angle displayed
last time is saved, so that it is restored when the power is turned on next time.
When the restored horizontal angle is not necessary, reset it to 0.
5.2 Resetting the horizontal angle to 0
Pressing [F3] [0 SET] twice in succession
resets the horizontal angle to 0° 0' 0".
The [F3] [0 SET] cannot reset the vertical angle to 0.
Pressing the [F3] [0 SET] accidentally during measurement does not reset the
horizontal angle to 0 unless you press it again. Once the buzzer stops sounding,
you can go to the next step.
You can reset the horizontal angle to 0 any time except when it has been held.
