Functions and applications:

• To measure the Pulse Width transmitted by Transmitter for up to 9 channels.
• To measure the Pulse Width sent from Receiver.
• To test the rotations of Servo automatically – at the pulse widths of top, medium and low points set by user already.
• To test the automatic rotations of Servo.
• To test the rotations of Servo by turning the knob on the tester manually .
• To test the sensitivity of Servo (1μS per step minimum).
• To measure RPM of a spinning propeller – for 2 – 6 blades ones, real time RPM value shown／to set the peak RPM value up to 99990 per minute.
• Shiny 4 digits red LED's to display the values measured.
• Power source can be from UM-4 / AAA cell x4, or an adapter with 7-15V or BEC (5V) from an ESC.
• An output port for applying Positive/Negative signals of Pulse Width from this tester.
• Four buttons for setting up functions and modes.
