1. The product has reliable performance, and the outer shell is made of aluminum alloy, with an overall size of 355X200X155mm.

2. The product has reliable performance, with a 7-inch color touch screen and a resolution of 1024X600. Except for the voltage value that needs to be set by pressing the button, all other parameters are set on the touch screen.

3. Built in 0-53V5A programmable power supply, which can easily set any voltage value. When the load changes, this power supply will automatically adjust the voltage to maintain the same as the set voltage.

4. With built-in oscilloscope function, the current waveform and FG signal waveform can be displayed simultaneously. The current waveform voltage is 50mA, 100mA, 200mA, 500mA, and 1000mA in five levels. The FG waveform voltage is 1.0V, 2.0V, 5.0V, and 10V in four levels. Six options for time: 250us, 500us, 1.0ms, 2.5ms, 5ms, and 10ms.

5. Easy to use, you only need to connect the fan to the tester to test the speed, with fan polarity reversal and short circuit protection function

6. Speed, current, voltage, and power display can be used as a separate programmable DC power supply

7. DC Fan Test: Can test 2-wire, 3-wire, 4-wire PWM and brushless fans with FG and RD signals

8. AC Fan Test: Using an infrared sensor head for testing, there is no need to label the fan during testing, and the speed can be accurately tested

9. PWM output, divided into automatic/manual control, manual 0-100% duty cycle adjustable, automatic divided into four sections, each section's duty cycle adjustable, and each section's speed displayed separately. Sections 2, 3, and 4 can be individually set on and off. The interval time of each section can be set from 1 to 99 seconds. The PWM output voltage can be selected as 10V, 5V, or 3.3V. The output frequency can be selected as "25KHz, 6.25KHz, 1KHz, 200Hz, 100Hz"

10. VsP voltage modulation output controls the speed of the fan, and VsP VPP output is available in 10V, 5V, and 3.3V options.

11. FG pull-up selection, you can choose internal pull-up, external pull-up, or no pull-up.

12. FG signal low value automatic judgment function.

13. The maximum and minimum speed limits can be set, the horn will alarm if the limit is exceeded, and PASS will be displayed if it is qualified

14. Automatic judgment of speed and current. Qualified display: "PASS"
