Glossary
recording mode
In the Settings Interface menu, recording mode can be set as [ALL] or [Confirm].
When you set recording mode to
[ALL], press [MEAS/ENT] takes a measurement and
records the point with the default point number/code by one key press.
When you set recording mode to
[Confirm], the program will show you the recording
contents before it returns to the observation screen.
Recording settings can be set to
[Yes] or [No].
If the recording settings are set to
[Yes], a series of observation condition settings
will be recorded whenever you reboot the program. See Configuring data
recording and external communication settings, page 38.
reflector
The target (usually refers to a prism).
reflectorless
Refers to direct-reflex mode.
regional configuration
presets
Three regional configuration presets are recorded on the Trimble M3 total station.
When you first start using the instrument, and you have selected the language, the
REGIONAL CONFIGURATION screen appears from which you can select a
region. See Changing regional configuration presets, page 32.
remote object
Heights of inaccessible points are determined by measuring SD, V to an accessible
point in the vertical line. See Remote object height, page 100.
resection
One of the methods to set up the station. By measuring to two or more known
points, the program will calculate the station coordinate and its orientation.
residuals
The indicator for the observation accuracy and reliability in resection result. If this
is small enough, you can judge the new station setup is successfully done.
reticle
A system of wires, hairs, threads, etched lines, or the like, placed in a telescope
perpendicular to its axis and at its principal focus, to define the line of sight of the
telescope, to permit specific pointings to be made on a target or signal, or readings
to be made on a rod or scale.
RS-232
This was originally a nine-wire interface standard for teletype machines from the
Electronics Industry Association. It is the standard for computer serial-port
transfers
scale
A multiplier used on coordinate and other linear variables, such as for map
projections and transformations.
scale factor
A map projection parameter used to convert ellipsoid distances to projection
(grid) distances, and vice versa.
SD
Slope distance.
sea-level correction
One of the coordinate conversion corrections referring to the sea-level. You can
set it to ON or OFF. See Configuring error corrections, page 40.
spatial eccentricity
One of the eccentricity application function. It calculates the point by using the
input spatial distance Ts. See Eccentric measurement, page 85.
