Function Description:

1. Voltmeter/Ammeter: 4 digit LED DC Voltage / Current Ampere Display.

2. Tachometer: 5 digit LED Fan RPM Display Meter.

3. Current Upper/Lower Limit Setting: 4 digit dial switch for setting fan current upper/lower limit value.

4. RPM Upper/Lower Limit Setting: 5 digit dial switch for setting fan rpm upper/lower limit value.

5. Delay Test Time Setting: 2 digit dial switch for setting delay for fan to be started under low voltage.

6. 2 digit dial switch can be used to set the sampling time for normal voltage operation and current test of the fan.

7.  The voltage/current value shows the switch

8.Switching between Volt/Amp Displays: Volt/Amp display Selection Switch.

9.Identifying Range of Current between Upper/Lower Limits: OK indicator light identifying current Within Upper/Lower Limits.

10.Voltage adjustment: For adjusting low volt Start/Normal testing voltage.

11. Testing Result Judging: Test result OK/NG (Not Good) Identify indicator light.

12.With 2T / 3T signal input switching function.

13.Contains 2 sets of DC power supplies

14. Detects broken wires in the fan's internal coils.

15.Abnormal alarm.

16.DC Power Supply: 2 sets of DC Power Supply.

17.The output end of this machine is equipped with an oscilloscope terminal block, which can measure the fan power consumption waveform and FG signal at the same time.

18. This device is equipped with RS232C test data transmission function, and the measured speed value and power consumption data can be transmitted to the data collector, other computers as production history data, and production inspection trend graphs. Or can be converted into EXCEL files to create production history and other functions (but this device does not include Microsoft Window system software).
