7. Mod Pengukuran

7.1 Infrared (Non-Contact) Temperature Measurement

This mode measures the surface temperature of an object without physical contact.

1. Point the infrared sensor towards the target surface.
2. Tekan dan tahan butang Pencetus. The laser pointer will activate (if enabled) to indicate the measurement area.
3. The surface temperature will be displayed on the screen.
4. Lepaskan Pencetus to hold the reading.

Imej 7.1: Illustration of the 12:1 Distance-to-Spot (D:S) ratio, indicating that the measurement area (spot) diameter increases with distance from the target. For example, at 12 inches, the spot diameter is 1 inch.

7.2 Type-K Thermocouple (Contact) Temperature Measurement

For accurate contact temperature measurements, use the included Type-K thermocouple probe.

1. Insert the Type-K thermocouple probe into the dedicated socket on the side of the thermometer.
2. Tekan ke Mod button until the Type-K measurement mode is indicated on the display (often with a 'K' symbol).
3. Place the tip of the thermocouple probe in direct contact with the surface or substance to be measured.
4. The temperature reading from the thermocouple will be displayed.

7.3 Ambient Temperature, Humidity, and Dew Point Measurement

The device continuously monitors ambient conditions.

• The ambient air temperature, relative humidity, and dew point temperature are displayed on the screen automatically.
• These readings are taken by the internal humidity sensor.

7.4 Mould Risk Detection

The thermometer provides a visual indication of mould risk based on the dew point.

• A tricolor LED light (green, yellow, red) indicates the proximity to the dew point.
• hijau: Low risk, conditions are fine.
• Kuning: Near critical dew point, increased risk of mould growth.
• merah: High risk, conditions are conducive to mould growth.

8. Pelarasan Emisiviti

Emissivity (ε) is a measure of an object's ability to emit infrared energy. Different materials have different emissivity values. For accurate infrared temperature measurements, it is important to set the emissivity value on the thermometer to match the target material.

• The WT323C allows adjustment of emissivity from 0.1 to 1.0.
• To adjust emissivity, press the Mod button until the emissivity setting (ε) is displayed.
• Use the up/down arrow buttons (often integrated with °C/°F or Laser/UV buttons in mode settings) to change the value.
• Refer to a standard emissivity table for common materials if precise values are needed.

9. Penyelenggaraan

• Pembersihan: Lap peranti sehingga bersih dengan kain lembut,amp kain. Jangan gunakan pembersih atau pelarut yang melelas.
• Storan: Store the thermometer in a dry, cool place away from direct sunlight and extreme temperatures.
• Penggantian Bateri: Gantikan bateri apabila penunjuk bateri lemah muncul pada paparan.
