Introducing the HJ Digital Servo Tester/ESC Consistency Tester - a versatile tool for RC hobbyists. Made of durable plastic and colored in blue and black, it weighs 0.88 oz (25 g) and measures 7.5 cm x 3.8 cm x 2.5 cm.
This tester allows you to synchronize output control for up to 4 servos and compare the performance of steering gear control. With a signal accuracy of up to 2us (1 millisecond = 1000 microseconds), you can easily test the steering gear's responsiveness to subtle changes. Additionally, it features a PPM signal test function in the display, which synchronizes the input PPM signal output to the servo while changes occur.
Upon being energized, the tester automatically enters manual mode (Manual) with a cycle of 20us. It has a 50H analog servo signal cycle with a frequency of 50Hz, and a rotary potentiometer that allows you to adjust the output pulse's width.
The tester comes with a Select button that cycles through the following modes:
- S-1 manual mode (Manual)
- S-2 bit mode (Neutral)
- S-3 automatic mode (Automatic)
It also has a Keys pulse width function with the following cycle and frequency options:
- 50H analog servo signal cycle 20us frequency 50Hz
- 125H digital the steering gear a signal cycle 8us frequency 125Hz
- 250H Digital Servo signal cycle 4us frequency 250Hz
Note that the tester requires you to select the corresponding digital or analog signal button before plugging in the steering servo to avoid causing damage.
The package includes one HJ Digital Servo Tester/ESC Consistency Tester and mounting hardware.
