1. The product has reliable performance, and the outer shell is made of aluminum alloy, with an overall size of 300X150X140mm.

2. Use a 4.3 inch color touch screen, except for the voltage value that needs to be set by pressing the button, all other parameters are set on the touch screen.

3. Equipped with a built-in 0-53V programmable power supply, it is convenient to 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. Easy to use, simply connect the fan to the tester to test the speed, with fan polarity reversal and short circuit protection function

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

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

7. 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

8. PWM output, divided into automatic/manual control, manual 0-100% adjustable duty cycle, automatically divided into four sections,

The duty cycle of each section is adjustable and the speed of each section is displayed separately. Sections 2, 3, and 4 can be individually set to on,

Off. The interval time of each segment can be set arbitrarily from 1 to 99 seconds. PWM output voltage can be selected

5V or 3.3V. The output frequency can be selected as "25KHz, 2KHz, 1KHz, 200Hz, 100Hz, 50Hz"

9. FG pull-up resistor can be selected, including internal 10K resistance pull-up, external 10K resistance pull-up or

There is no resistance pull-up (this mode requires that there is a pull-up resistor inside the fan, otherwise 0V will be output, and there is no square wave

Output).

10. 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

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