# Instrument functions

To access the Instrument functions screen, tap the instrument icon in the status bar.

The functions available depend on the instrument that the controller is connected to. A yellow button indicates the function is enabled.

When in the Instrument functions screen, you can use the controller keypad to enter the keypad character (1–9, 0, - or .) indicated on the tile to enable/disable the function or open the appropriate screen. If you have configured a function key on the controller as a shortcut to an instrument function, you can press the configured function key when viewing any screen in the software.

EDM and laser pointer controls

To switch EDM measurement mode, tap the first button in the Instrument functions screen to cycle through the available modes.

- For most Trimble instruments, when you select:
  - STD, the instrument is in EDM Standard mode, where it averages the angles while a standard distance measurement is taken.
  - FSTD, the instrument is in EDM Fast Standard mode, where it averages the angles while a fast standard measurement is taken.
  - TRK, the instrument is in EDM Tracking mode, where it constantly measures distances and updates them in the status line.

  Fast Standard mode is not available for the Trimble SX10 or SX12 scanning total station.

- For a Trimble C3 and C5 total station, when you select:
  - Normal, the instrument averages the angles while a standard distance measurement is taken.
  - Fast, the instrument averages the angles while a fast standard measurement is taken.
  - Precise, the instrument constantly measures distances and updates them in the status line.

To enable or disable the laser pointer, tap Laser or 3R HP Laser. To configure EDM settings, tap and hold the Laser or 3R HP Laser button.
