Turn around the aiming component and aim at the target,
press soft key „F1‟ again and the horizontal angle is set at a new
position.
When the horizontal angle is hold, any key beside „Hold‟
will exert no effect on the instrument.
L/R:
Press soft key „F2‟, the horizontal angle column is
switched between HR and HL modes.
HR indicates that the angle increases as the instrument
turns clockwise around the vertical axis
HL indicates that the angle increases as the instrument
turns anti-clockwise around the vertical axis
VA:
Press soft key „F3‟, the vertical angle column is switched
Vz is Zenith Mode
Vo indicates that when the telescope is leveled, the vertical
angle is displayed as 0°0′0″at face one.
Vh is vertical angle Mode (being 0 and has a positive
angle of elevation and a negative angle of depression)
V% is Slope Mode. The range for slope that can be
displayed is between -99.9999% and 99.9999%. If the slope is
over the range, „Overtop!‟ is displayed in the vertical angle
column
When setting the horizontal angle, the set angle is the
azimuth angle of the target. The instrument may be switched to
display grid bearing through these operations.
