EDM settings

Use the EDM settings screen to configure settings for the electronic distance meter in the instrument. The available settings depend on the type of instrument that the controller is connected to.

To view the EDM settings screen:

  • Tap and select Instrument/ EDM settings.
  • Tap the instrument icon in the status bar to view the Instrument functions screen and then tap and hold the Laser or DR button.

Set the Direct Reflex switch to Yes to enable DR mode.

When the EDM is in DR mode, it can measure to non-reflective instruments. When you turn on DR, the software automatically switches to Target DR. When you turn off DR, the software returns to the last used non‑DR target.

You can also enable DR mode by tapping DR in the Instrument functions screen, or by changing the target to Target DR.

Select the Laser pointer check box to enable the laser pointer. You may need to enable the Direct Reflex switch in the EDM settings screen to enable DR mode and make the Laser pointer check box available.

You can also enable or disable the laser by tapping Laser in the Instrument functions screen.

To streamline the process of locating a prism in dark environments, enable the LaserLock check box in the Target controls screen and switch on the laser by tapping the Laser tile in the Instrument functions screen. See Target control settings.

To blink the laser and the tracklight when storing a point measured with DR mode, select the number of times the laser will blink in the Blink laser field.

To define the acceptable accuracy of a measurement, enter a Prism standard deviation or DR standard deviation value, depending on the mode the instrument is in. When measuring to diffuse targets the standard deviation is displayed on the status line until the standard deviation satisfies the defined value. Once the standard deviation is satisfied, the measurement is accepted. To accept the measurement before the standard deviation is satisfied, tap Enter while the standard deviation is displayed on the status line.

Enter a suitable DR minimum and maximum distance for your survey. Increasing the maximum distance will increase the time that it takes for a measurement to complete, even if the distance being measured is less than the specified maximum. The default maximum distance provides a balance between measurement time and range. Increase the maximum distance if you are working at longer ranges. To restrict the DR measurement range, enter a minimum and maximum distance to avoid a result from a distant or intermittent object.

Use the long range mode when a strong instrument signal is required for measuring to targets more than one kilometer (about 0.6 miles) away.

To accept measurements at a lower accuracy (that is, below the normal instrument specification), enable Weak signal.

Use 10 Hz tracking when a faster update rate is required when using Tracking mode.

 

  • This option is only available if you are in both Autolock and Tracking mode. If you select DR or turn off Autolock when tracking, the software will default to normal tracking mode.
  • Although tracking is faster the precisions will be null for the stored point.
