4.Frequency set rang e
There is two work mode so it have two frequency rang e.
Normal mode:Frequency rang e 1Hz~150KHz.Duty cycle rang e 000%-100%.Duty cycle accuracy 1%.
Precise mode:Frequency rang e 1Hz~15KHz.Duty cycle rang e 0.00%-100%.Duty cycle accuracy 0.1%.
Enter the settings interface when short press rotary switch in the normal running statu s to select frequency rang e.Rotary potentiometer to set frequency value.
Keep press rotary switch for 10second to switch Normal mode and Precise mode.
Keep press for 5second to locking parameters to protect the parameters from being modified.
Pay attention to the position where the decimal point moves when rotary potentiometer..
Display ‘XXX’.No decimal point, The min imum frequency is 1Hz. The frequency rang e is 1Hz ~ 999Hz.
Display ‘X.XX’. The decimal point is the penultimat e, The min imum frequency is 0.01KHz. The frequency rang e is 1.00KHz ~ 9.99KHz.
Display ‘XX.X’. The decimal point is the third last, The min imum frequency is 0.1KHz. The frequency rang e is 10.0KHz ~ 99.9KHz.
Display ‘X.X.X’. The decimal point is fully lit, The min imum frequency is 1KHz. The frequency rang e is 1KHz ~ 150KHz.
For example
Display ‘100′ means PWM output frequency is 100Hz;
Display ‘1.91′ means PWM output frequency is 1.91KHz;
Display ‘52.1’ means PWM output frequency is 52.1KHz;
Display ‘1.3.4′ means PWM output frequency is 134KHz;
5.Duty cycle set rang e
Short press potentiometer to select set duty cycle and rotary potentiometer to set duty cycle value.
