Instruccions de funcionament
This section details the procedures for using the testing instrument for various diagnostic tasks.
1. Inverter Compressor Detection:
- Connect the inverter compressor to the designated port on the tester (refer to Figure 2, item 4).
- Adjust the frequency using the "Frequency Adjustable" knob (Figure 2, item 1) to simulate different operating conditions.
- Observa el voltage and current readings on the display (Figure 2, items 2 & 3) to assess compressor performance.
2. Solenoid Valve Detection:
The instrument supports testing of both pulse solenoid valves and mainboard output to solenoid valves.
- For pulse solenoid valve detection, connect the valve to the corresponding port (Figure 2, item 6).
- For mainboard output detection, connect the mainboard output to the specified port (Figure 2, item 7).
- Monitor the instrument's display for proper signal and operation.
3. Fan Motor Detection (3-wire and 4-wire):
The tester can diagnose both 3-wire and 4-wire fan motors commonly found in refrigerators and air conditioners.
- Connect the fan motor to the appropriate 3-wire (Figure 2, item 16) or 4-wire (Figure 2, item 17) fan detection port.
- Activate the test function and observe the fan's operation and any readings on the display.
4. Compressor Cylinder Jamming Repair:
This function assists in attempting to repair slight compressor jams caused by overheating. The instrument will attempt to drive the compressor cylinder three times.
Figure 6: The testing instrument connected to a refrigerator compressor, demonstrating the setup for diagnosing or attempting to repair a jammed compressor.
If the compressor does not start after three attempts, a buzzer alarm will sound, indicating a persistent issue.
