FOIRE AUX QUESTIONS - UT306C Uni-T

Comment allumer le thermomètre UT306C ?

Appuyez sur la gâchette (bouton de mesure) pour allumer l'appareil. Un écran LCD s'allume et le thermomètre est prêt à mesurer.

Comment changer l'unité de température (Celsius/Fahrenheit) ?

Lorsque l'appareil est allumé, appuyez simultanément sur les boutons 'MODE' et 'SCAN' (ou consultez la notice). Généralement, un bouton dédié permet de basculer entre °C et °F.

Quelle est la distance de mesure optimale ?

Pour une précision optimale, tenez le thermomètre à environ 15 à 30 cm de la cible. Le rapport D:S (distance:spot) étant de 12:1, la taille de la zone mesurée est la distance divisée par 12.

Que faire si l'affichage indique 'Err' ou 'OL' ?

Ces messages indiquent que la température mesurée est hors de la plage spécifiée (-50 °C à 380 °C) ou que l'appareil ne peut pas effectuer une mesure fiable. Vérifiez la cible et la distance.

Comment nettoyer la lentille du thermomètre ?

Utilisez un chiffon doux et non pelucheux légèrement humide (eau ou alcool isopropylique) pour nettoyer délicatement la lentille. Ne pas utiliser de produits abrasifs.

Quand faut-il remplacer les piles ?

Lorsque l'icône de batterie faible apparaît sur l'écran, remplacez les deux piles AAA par des neuves. Utilisez des piles alcalines pour une durée de vie optimale.

L'appareil dispose-t-il d'un laser ? Est-il dangereux ?

Oui, un laser de classe 2 (< 1 mW) est intégré pour aider à viser. Évitez de le diriger vers les yeux. Ne pas regarder directement le faisceau.

Comment fonctionne l'arrêt automatique ?

L'UT306C s'éteint automatiquement après environ 15 secondes d'inactivité pour économiser les piles. Vous pouvez le rallumer en appuyant sur la gâchette.

Peut-on mesurer la température des liquides ou des surfaces brillantes ?

Les liquides clairs et les surfaces métalliques polies réfléchissent les infrarouges, ce qui peut fausser la mesure. Utilisez du ruban adhésif mat ou de la peinture noire, ou bien l'émisstivité réglable (si disponible) pour améliorer la mesure.

Operating Instructions

Startup

Short press (less than 0.5s) the trigger to turn on the thermometer, and the measured value before the last shutdown will be displayed. Pressing MODE button can view MAX/MIN/AVG/DIF.

Shutdown

The thermometer will automatically shut down after 15 seconds without any operation in the HOLD mode, and save the current measured value.

Manual Measurement

1) After aiming at the measured object, press the trigger and hold it. When the SCAN symbol is flashing, it means that the temperature is being measured, and the measurement result will be updated on the LCD.

2) Release the trigger, the SCAN symbol will disappear while the HOLD symbol will be displayed. The thermometer will stop measuring the temperature and keep the last measured value.

Lock Measurement

1) Short press the LOCK button to enter the lock measurement mode. The 🔒 symbol will be displayed on the LCD and the SCAN symbol will flash. The thermometer will measure the target temperature continuously without pressing the trigger all the time.

2) Press the trigger or short press the LOCK button again, the 🔒 and SCAN symbols will disappear while the HOLD symbol will appear. The thermometer will stop measuring and keep the last measured temperature.

3) Short press the LOCK button in the shutdown state to wake up the thermometer and enter the lock measurement mode.

4) If the LOCK button is pressed and not released for more than 3 seconds, it will be regarded as a misoperation.

Note: The measured target should be greater than 2 times the thermometer light spot diameter (S), and then the test distance (D) can be determined according to the D: S relationship diagram.

For example: when the user uses UT306C to measure the temperature of an object with a diameter of about 4" (10cm), the most accurate spot diameter (S) of the thermometer is about 2" (5cm), and then it can be estimated based on the D:S relationship diagram that the measuring distance (D) is about 24" (60cm).

MAX/MIN/AVG/DIF Value

Short press the "MODE" button to switch among "MAX→MIN→AVG→DIF" measurement modes in sequence, and the temperature of the corresponding mode will be displayed in the secondary display position (as shown below).

Laser Indicator

Pressing the 🔒 button can turn on/off the laser indication function. When it is turned on, the laser symbol 🔒 will show on the LCD, and the laser will accurately indicate the measured position.

Note: Please follow the cautions when turning on the laser to avoid eyes injury.

High and Low Temperature Alarm

If the measured temperature is higher than the set high alarm limit, the HI symbol on the display will flash. If the sound alarm is turned on, the buzzer will beep.

If the measured temperature is lower than the set low alarm limit, the LO symbol will flash. If the sound alarm is turned on, the buzzer will beep.

If the measured temperature value is within the range of high and low alarm limit, the HI/LO symbol will not show on the display.

Function Settings

In the HOLD interface, long press the "MODE" button for more than 2s to enter the high alarm limit → low alarm limit → emissivity → temperature unit → sound alarm and other function settings. Under these setting interfaces, the user can return to the HOLD interface by pressing the trigger or no operation for 10s.

High Alarm Limit Setting

In the HOLD interface, long press the "MODE" button to enter the high alarm limit setting interface. The user can use "▼" or "▲" to adjust. Short pressing will add or subtract 1 to the value each time, and long pressing will add or subtract 10 each second.

Low Alarm Limit Setting

In the HOLD interface, long press and then short press the "MODE" button once to enter the low alarm limit setting interface. The user can use "▼" or "▲" to adjust. Short pressing will add or subtract 1 to the value each time, and long pressing will add or subtract 10 each second.

Emissivity Setting

In the HOLD interface, long press the "MODE" button once and then short press the "MODE" button twice to enter the emissivity setting interface. The user can use "▼" or "▲" to adjust. Short pressing will add or subtract 0.01 to the value each time, and long pressing will add or subtract 0.1 each second.

Temperature Unit Setting

In the HOLD interface, long press the "MODE" button once and then short press the "MODE" button three times to enter the temperature unit setting interface. The user can use "▼" or "▲" to convert the unit °C/°F.

Sound Alarm Setting

In the HOLD interface, long press the "MODE" button once and then short press the "MODE" button four times to enter the sound alarm setting interface. The user can use "▼" or "▲" to turn on/off this function.

D: S (Distance to Spot Ratio)

As the distance (D) between the thermometer and the measured target increases, the light spot diameter (S) of the measured area also increases.

The relationship between measurement distance and light spot diameter is shown in the figure below.

Field of View

When measuring, make sure that the measured target is larger than the light spot diameter. The smaller the target, the closer the test distance should be (refer to D: S for the detailed light spot diameter). It is recommended that the measured target be larger than twice the light spot diameter of the thermometer.

Emissivity

Emissivity represents the material energy radiation. The emissivity of most organic materials, painted or oxidized surfaces is about 0.95. The user can use masking tapes or flat paints to cover the metal surface, use the high emissivity setting, and then wait for a period of time to make the surface temperatures of the tapes/flat paints and the covered object the same. At this point, the surface temperature of the tapes/flat paints is equal to the metal surface temperature. The following table shows the total emissivity of some metals and non-metals.
