1. The product has reliable performance, LCD dot matrix display, small size, and is very convenient for assembly line production and use

2. Easy to use, simply connect the fan to the tester to test the speed, with fan polarity reversal and short circuit protection function

3. Current, voltage, and power display can be used as a separate DC power source

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

5. AC fan test: A separate infrared sensor head is required for testing, and there is no need to label the fan during testing, which can accurately test the speed

6. 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 the interval time of each section can be set from 1-99 seconds. PWM output voltage can be selected from 5V or 3.3V

7. The maximum and minimum speed limits can be set, and the horn will alarm if the limit is exceeded

8. The maximum and minimum current limits can be set, and the horn will alarm if the limit is exceeded

9. It can be connected to the BNC head of the tester through an oscilloscope for convenient testing of current waveforms

10. The testing methods are divided into fast testing and average testing, with the average testing method being more accurate

11. Automatically determine speed and current. Qualified display: "PASS"
