Now press „F4‟ to save the settings or „ESC‟ to quit. If the set
angle is greater than 360°, the instrument will display „HA
overtop!‟
On the Second Page:
Hold: used to set horizontal angle
Turn around the alidade to the wanted horizontal angle and
press soft key „F1‟ and the readout of horizontal angle is „hold‟
and not changing with turning the alidade again.
After turning the alidade to aim at the target ,you may press
soft key „F1‟ again to set horizontal angle at a new position.
When the horizontal angle is hold, any key beside „Hold‟
will don‟t work 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 turning the alidade
clockwise.
HL indicates that the angle increases as turning the alidade
anti-clockwise .
VA:
Press soft key „F3‟, the vertical angle column is switched
between Vz, Vo, Vh and V%
Vz is Zenith Mode
Vo indicates that when the telescope is leveled, the vertical
angle is displayed as 0°0′0″ at face left.
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 angle is the azimuth angle of the
target. The instrument may be switched to display coordinate
azimuth through these operations.
