- Carefully immerse the probe into the hot oil. Ensure the immersion depth is sufficient (approximately 1.38 inches / 35 mm) to cover the sensor.
- Hold the device steady. The display will show the temperature and Total Polar Material (TPM) percentage ພ້ອມໆກັນ.
- The device features a traffic light system for TPM levels:
- ສີຂຽວ: Oil quality is good (TPM below threshold, typically < 20%).
- ສີສົ້ມ: Oil quality is borderline (TPM approaching threshold, typically 20-24%).
- ສີແດງ: Oil quality is poor, oil needs changing (TPM above threshold, typically > 24%).
- Use the "HOLD" function to freeze the displayed measurement for easier reading.
- Remove the probe from the oil after measurement.
