7ch Analogue Digital Servo & ESC Tester
The 7-Channel Analogue / Digital Servo Tester is a servo response consistency master.
Its accuracy lets you perform various servo response tests before installing it into your RC models.
It is highly useful for quadcopters (multi-rotor) or helicopters setup as you can test upto 7 servos at once. 
The servo tester has three different modes.
First is manual, it starts at 800 and the little dial adjusts it up to 2200.
So, for example, if the motor doesn't start until a little above 1100 and hits max a little below 2000 would indicate ESC is working correctly.
Hit the left button once and it goes to 1500 with no adjustment from dial, makes testing mid throttle thrust easy.
The third mode is a sweep, it cycles from 1500 down to 800, then up to 2200 automatically.
The dial controls how rapidly it changes, on it's lowest setting you should be able to hear where there are resonate frequencies, see/hear when motor reaches maximum, etc.
Turning the dial up will increase sweep speed and will give an idea how your motor reacts to fast throttle changes.

Features:
  • Synchronized output control of 4 servos and compare the performance.
  • Servos output signal accuracy up to 2us (1 milliseconds = 1000 microseconds), you can test the servos response only with subtle changes.
  • With PPM signal test function in the display, the input PPM signal changes while the input the PPM signal synchronization output to the servo energized automatically enter manual mode (Manual) 20us.
  • 50H analogue servo signal cycle, frequency 50Hz, rotary potentiometers to decrease or increase the width of the output pulse
  • Select Button (Note: switch in circular pattern)
    • S-1 manual mode (Manual)
    • S-2 bit mode (Neutral)
    • S-3 automatic mode (Automatic)
  • Pulse Width Button
