Application:

1. As square wave signal generator for experimental development; 

2. As square wave signal generator for motor driver;

3. As adjustable pulse generator for MCU; 

4. As pulse generator, control related circuits (PWM dimming, speed regulating).

Frequency Display Instruction:

The frequency is divided into 4 ranges and switched automatically.

1. XXX (without decimal point): minimum unit 1Hz, value range 1Hz~999Hz.

2. X.XX (decimal point in the hundred digit): minimum unit 0.01kHz, value range 1.00kHz~9.99kHz.

3. XX.X (decimal point in the ten digit): minimum unit 0.1kHz; value range 10.0kHz~99.9kHz.

4. X.X.X (full decimal point): minimum unit 1kHz; value range 1kHz~150kHz.

e.g. 

(1) Frequency displays 100 represents 100Hz; displays 1.01 represents 1.01kHz; 

(2) displays 54.1 represents 54.1kHz; displays 1.2.4 represents 124kHz.
