5. Ask the rod person to adjust the target position. When the target is on the 
intended position, the displayed errors become 0.000 m (0.000 ft).
Once a measurement is taken, the Cut/Fill value and Z coordinate are updated

Curvature and refraction corrections
Because the surface of the earth is curved, the vertical difference (VD and Z) at the 
measurement point, as referenced to the horizontal plane, inevitably includes some 
error. This error is called curvature error. Also, because the density of the air 
surrounding the earth decreases with altitude, light is refracted at different rates at 
different altitudes. The error caused by this change in refraction is called refraction 
error.

Use the Data menu to view or edit records. To display 
the Data menu, press [3] on the MENU screen.
Raw and coordinate data is stored when the Data Rec 
setting is ON. If the Data Rec setting is OFF, no data is 
recorded in [MENU] / Data / Data Rec.

SS and F1 records
Raw SS and F1 records contain PT, HT, CD, HA, VA, and SD fields.
SS records are sideshots (topo shots). All shots taken from the Basic Measurement 
Screen (BMS) are stored as SS records.
F1 records are backsight shots that are taken when you set up a station. Coordinates 
are not available for an F1 record.
When you take more than one measurement to the same point and choose to 
overwrite the XYZ data, the old raw record becomes raw data only. As a result, only 
one SS (RAW) record keeps its corresponding SS(XYZ) record. Other SS(RAW) records 
to the same point no longer have a record on their coordinates.

ST records
ST (station) records contain ST, HI, BS, and AZ fields.
Press [DISP] to switch between the screens:

•The third screen shows dX, dY, dZ, PT, and CD
The dX, dY, and dZ fields store the difference between the actual position and the 
planned position of the stakeout shot. These fields are downloaded as comment 
records in Nikon RAW format.
CO records
A CO record is a comment that is added to the job by the system.
For example, the system writes a comment record 
when you use the Remote Benchmark function to 
change the Stn-Z, or when you use the BSCheck 
function to reset the horizontal angle.
When you enter a Stn-XYZ by Base-XYZ function, the 
recorded station appears as a comment record.
