Units Settings
The Units Settings card defines the units that are used within the
software, sent from the total station, entered from the keypad and
displayed on the screen. You can select the following settings for your
project from the following dropdown lists.
Units for Distances : defines the units used for length as
Meters , Feet , or US Survey Feet .
Note: You can enter a distance in any distance field in
units other than what is set for the job by appending the
distance value with the following characters:
y f or ft Feet
y
usf or usft US Survey Feet
y
i or in Inches
y m Meters
y cm Centimeters
y
mm Millimeters
y
c or ch Chains
Once the cursor leaves that field, the distance will be
converted automatically. (A space between the value and
the unit abbreviation is optional.)
Warning: When creating a new job, it is important that the Units for
Distances field be set to the correct units. This allows you to
seamlessly switch between different units in mid-job.
Problems can arise if these units are inadvertently set to the incorrect
units when entering new data. For example, assume you created a
control file by hand-entering a list of coordinates in a new job where
the job was set to
Feet and the coordinates being entered were in US
Survey Feet. Now assume you created another new job and correctly
set it to
US Survey Feet . If you then selected the previous job as a
control file for the new job, the display of all of the coordinates in the
control file would be converted from Feet to US Survey Feet.
