2. Tap the button to drop down the list of available screens and
then tap Repetition .
3. Set the Horizontal , Zenith , and Distance Tolerances in the
appropriate fields. The direct shots for each set are compared to
the corresponding reverse shots. If any of the angles or distances
exceeds the specified tolerances, the Repetition Error dialog box,
shown here, will open that asks what you want to do. You have
the following choices:
• 5HWU\ : Re-shoot only the last set.
• &RQWLQXH : Continue and use the shot
anyway.
• &DQFHO : Throw out all sets and start
over.
4. If the Shoot Distance To Backsight
checkbox is selected, distances will also be
measured with each shot to the backsight
and compared against the specified
Distance Tolerance . This option, of course,
would require a prism to be setup over the backsight point.
5. The Do Not Shoot Reverse Distances checkbox is available for
people that use total stations that cannot measure distances
when in the inverted, face two, position. Check this if you use
this type of total station.
6. The Enable Automatic Repetition checkbox is for users with
motorized total stations. When this is checked, the first shot to
the backsight and foresight is performed normally, but when
those shots are complete the total station will perform all the
remaining shots for each set automatically unless the user
interrupts the sequence.
7. The Shooting Sequence defines the order that the forward and
reverse shots are performed for each set. The notation used
should be read where the
> symbol indicates to aim the telescope
to the next point and the ^ symbol indicates that the total station
should be flopped from face one to face two or vice versa. Each
option is explained below.
