TEST SETTINGS

Tap the video to move the box onto the LED / disc mark. Dashed line = detection threshold.

HOW IT WORKS
  • 1 Set IMP at the top, then Load, REV and Load Watt above
  • 2 Aim the camera at the meter and tap the video to put the box on the LED
  • 3 Press START (no scrolling needed) — after the delay, the timer begins on the first pulse
  • 4 After the set REV count it beeps, stops, and shows the error
