Typical Application:
1. Used as a square wave signal generator, generate square wave signal for experimental development and use;
2. Used to generate a square wave signal that controls the motor driver;
3. Output adjustable pulse for MCU use;
4. Output adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
Adjusting Mode
PWM output, set the frequency and duty cycle independently.
Normal adjusting mode:
Frequency range:1Hz~150KHz Duty cycle:000~100%, duty cycle adjusting step 1%;
Fine adjusting mode:
Frequency range:1Hz~15khz Duty cycle:00.0~100%, duty cycle adjusting step 0.1%;
ON/OFF Button:
Signal output on or off, eable output, turn on/off output. NOT for turning off screen or meter.
Frequency output has four ranges, automatic switching:
1. XXX (no decimal point): min. unit is 1Hz, the value range of 1Hz ~ 999Hz;
2. X.XX (decimal point in the hundred) min. unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
3. XX.X (decimal point in ten): min. unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
4. X.X.X (decimal point in ten and hundred): min. unit is 1Khz; value range 1KHz ~ 150KHz
