2. After setting temperature and air pressure in the instrument, measure the Horizontal Distance of AB and AC
accurately.
3. Set the instrument on Point B and center it accurately, measure the Horizontal Distance of BC accurately.
4. Then you can get the Instrument Constant
：
K
＝ＡＣ－
(
ＡＢ＋ＢＣ
)
K should be closed to
０，
If
｜
K
｜＞５ｍｍ
,
the instrument should be strictly inspected in the standard
baseline site, and adjusted according the inspection value.
Adjustment
If strict inspection approves that the Instrument Constant K has changed and is not closed to 0. If the operator
wants to adjust, should set Stadia Constant according the Constant K.
●Set the direction by using the Vertical Hair to make Point A,B,C on the same line strictly. On Point there must be
fixed and clear centering mark.
●Whether the prism center of Point B coincides with the Instrument Center is the important tache to inspect the
accuracy. So on Point B Tripod or tribrach compatible should be used. That will decrease the difference.
24.10 Parallel Between Collimation line and Emitting Photoelectric Axis
Inspection
1. Set the reflector prism 50m from the instrument.
2. Sight the center of the reflector prism with reticle.
3. Power on and enter Distance Measurement Mode. Press [MEAS] to measure.
