By short press SET key, can shift display 4 parameter values (FR1:PWM1 frequency; dU1:PWM1 duty cycle; FR2:PWM2 frequency; dU2:PWM2 duty cycle); before shifting,there will be corresponding parameter name flashing 2. Directly press UP,DOWN key to modify current parameter value 3. 2 chhannel PWM are set 3 kinds frequency value, in frequency display interface,by long press SET to shift, 3 kinds frequency s duty cycle are the same (XXX:1Hz 999Hz; XX.X:0.1Khz 99.9Khz;X.X.X.:1Khz 150Khz) Setting PWM Frequency: 1. S1 FXXXT : set PWM1 frequency as XXX HZ (001 999) 2. S1 FXX.XT : set PWM1 frequency as XX.X KHZ (00.1 99.9) 3. S1 F:X.X.X.T : set PWM1 frequency as XXX KHZ (0.0.1. 1.5.0.) 4. S1

: PWM1 5. S2 : PWM2 6. F : frequency 7. D : duty cycle 8. T : stop sign bit Setting PWM Duty Cycle: 1. S1 DXXXT : set PWM1 duty cycle as XXX(001 100) 2. S2DXXXT : set PWM2 duty cycle as XXX(001 100) Setting successfully back: DOWN Setting unsuccessfully back: FALL Package List: 1 * Wave Rectangle Signal Generator
