Remote measurement

REMOTE DISTANCE

This function computes the distances between 2 remote shots.
Remote distance

remote distance screen
HI:

Enter the Height of Instrument.

HT:
Enter the Height of Target.

HA: , ZA:, SD:
Enter the horizontal angle, zenith angle and slope distance. To get this data from a total station, press the Measure function button in the upper left corner of the screen. The data is placed in the second point fields if the first point already has data in it.

After taking 2 shots, press Compute to display the remote Slope distance, Horizontal distance, and Vertical distance. Then the HA, ZA, and SD for the second shot is moved to the first shot, so you can take a series of shots for remote distance.

REMOTE ELEVATION

With this function a prism is shot directly below the place to be measured, and by then turning the scope up to the object and entering the new Zenith Angle, computes the height of the object. This is useful for heights of power lines, buildings, or other large objects used in construction.

HT:

Enter the Height of Target.

HA: , ZA:, SD:
Enter the horizontal angle (optional), zenith angle and slope distance. To get this data from a total station, press the Measure function button in the upper left corner of the screen.

ZA2:
Enter the zenith angle to the point above the prism, or press the Measure button to get this data from a total station. Then Press Compute to display the remote elevation (height above the ground of the object), then return to the HA: field for another shot. Press Menu to return to the main menu.

REMOTE POINT
Remote point

This function computes the coordinates of a remote point by shooting a special rod with 2 prisms on it at known distances apart. This is useful for getting accurate coordinates on points which are not visible but can be reached by the pole, such as manhole inverts, building corners, etc. The rod doesn’t need to be held plumb, and can be skewed at any angle. If it is skewed far from being perpendicular to the shot, the less accurate it will be because of the geometry. The only trick is that the rod must be held steady between the 2 shots. Many surveying supply shops sell a special rod from Seco made for this with 2 peanut prisms. If you have a reflectorless instrument, you can easily make your own special rod with PVC pipe and reflective tape instead of prisms.
Remote point screen

P1-P2:
Enter the known distance between the prisms.

P2-end:
Enter the known distance from the second prism to the end of the rod.

HA: , ZA:, SD:

Enter the horizontal angle, zenith angle and slope distance. To get this data from a total station, press the Measure function button in the upper left corner of the screen. The data is placed in the second shot fields if the first shot already has data in it.

After taking 2 shots, press Compute. The following prompts appear (same as in Collect or Stakeout):

From (occupied) point:
Enter the point number of the instrument location.

Ref. Point# or Brg:
Enter the desired reference point # (also called backsight point) and tap OK. Set the instrument Horizontal circle to zero on the Ref. Point. -Or- you may enter the bearing to the reference, and hit the Brg/Az button, and the program will create a ref. point for you along that bearing or azimuth. The prompt Save as ref.point# appears, enter a point# and press OK to create the point at 100′ along the line, or press Measure to shoot the distance to the Ref. point.

Enter the Height of Instrument.

Save as point#:
Enter a point number to save the calculated Remote point.

REMOTE SCANNER

This function is used with a reflectorless, motorized (servo) or robotic instrument to scan a defined area and automatically take a series of shots in a grid. Make sure your instrument is set to reflectorless mode before using this function. With robots, you connect direct to instrument, even though you leave Fieldworks Options-Instrument set as if it were connected with a radio. For a Topcon, you hit F1-PROG, F6-MORE, F2(or F3) EXT.LINK, F2-SETTING,F1, pick CABLE.
Remote scan screen

#H: Enter the # of points to shoot horizontally.

#Z: Enter the # of points to shoot vertically.

Shoot upper left pt:
Aim at the upper left point defining the area to scan, and press the Measure function button in the upper left corner of the screen.

Shoot lower right pt:
Press the Measure function button in the upper left corner of the screen. The HA and ZA defining the scan area are displayed.

Press Start if ready.

From (occupied) point:
Enter the point number of the instrument location.

Ref. Point# or Brg:
Enter the desired reference point # (also called backsight point) and tap OK. Set the instrument Horizontal circle to zero on the Ref. Point. -Or- you may enter the bearing to the reference, and hit the Brg/Az button, and the program will create a ref. point for you along that bearing or azimuth. The prompt Save as ref.point# appears, enter a point# and press OK to create the point at 100′ along the line, or press Measure to shoot the distance to the Ref. point.

Enter the Height of Instrument.

Start at point#:
Enter a starting point number to save the scanned points. The instrument will then start from the upper left to automatically shoot all the points in the defined area. It will display status messages to let you know what point it is on and if it had trouble making a shot. Tap the screen anywhere to stop early.
