Change the scale for the up and down arrow keys

The Loop Diagnostics screen has up and down arrow keys that let you manually adjust the current in small increments to slowly move a valve. The default increment is 0.1 mA, but you can adjust the scaling.

  1. On the Loop Diagnostics screen, tap Trex Unit Current > More Options > Arrow Scaling for mA.
    More Options does not appear unless the Trex Unit Power or Trex Unit Current is enabled.
  2. Enter a value between 0.04 to 10.00 mA.
  3. Tap OK.
  4. Tap Back to save the changes and return to the Loop Diagnostics screen.
