FOIRE AUX QUESTIONS - UT196 Uni-T

Comment mesurer une tension continue avec le UT196 ?

Tournez le sélecteur sur la zone DC V (tension continue). Branchez le cordon noir dans la borne COM et le cordon rouge dans la borne VΩ. Placez les pointes de test aux points de mesure. Lisez la valeur sur l'écran.

Le multimètre affiche '1' sur l'écran, que faire ?

L'affichage '1' signifie que la mesure dépasse la plage sélectionnée ou que les pointes ne sont pas connectées correctement. Vérifiez la position du sélecteur et le branchement des cordons.

Comment remplacer la pile du UT196 ?

Dévissez le compartiment à pile au dos de l'appareil. Remplacez la pile 9V usagée par une neuve de même type (6F22). Refermez le compartiment.

Quelle est la fonction 'Hold' sur le UT196 ?

La touche HOLD permet de figer la valeur mesurée sur l'écran. Appuyez une fois pour activer, à nouveau pour désactiver. Utile pour relever une mesure dans des conditions difficiles.

Comment tester une diode avec le UT196 ?

Placez le sélecteur sur le symbole diode. Branchez la sonde noire sur COM et la rouge sur VΩ. Touchez l'anode avec la rouge et la cathode avec la noire. L'écran affiche la tension de seuil. Si elle est inversée, 'OL' s'affiche.

Le UT196 peut-il mesurer des températures ?

Oui, avec un thermocouple de type K (non inclus dans toutes les versions). Tournez le sélecteur sur °C/°F et branchez le thermocouple dans les bornes COM et VΩ.

Que signifie l'icône de batterie faible ?

Une icône de pile apparaît lorsque la tension de la pile est insuffisante. Remplacez la pile rapidement pour éviter des mesures erronées.

Comment utiliser la fonction de mesure de fréquence ?

Sélectionnez la position Hz sur le sélecteur. Branchez les cordons comme pour une mesure de tension. Placez les pointes sur le signal à mesurer. L'écran affiche la fréquence en Hertz.

Le UT196 est-il adapté pour une utilisation automobile ?

Oui, il peut mesurer des tensions de batterie (12V/24V) et des résistances. Assurez-vous de respecter les catégories de sécurité (CAT III 600V). Utilisez les plages appropriées.

Comment nettoyer le multimètre UT196 ?

Débranchez les cordons et retirez la pile. Nettoyez le boîtier avec un chiffon doux légèrement humide. N'utilisez jamais de solvants ou de produits abrasifs.

• Prior to measuring in-circuit resistance, please turn off all powers in the measured circuit and discharge all capacitors completely.
• For low resistance measurement, the test lead may cause a measurement error of about 0.1Ω\~0.3Ω. To obtain accurate reading, please short-circuit the test lead and conduct measurement in REL mode.
• If the resistance is 0.5Ω when the test lead is short circuit, please check if the test lead is loose or if there is any other abnormal phenomenon.

• If the measured capacitor is short circuit or the capacitance value exceeds the maximum range, "OL" will appear on the display screen.
• It is normal to take several seconds to stabilize the reading.

• Do not input voltage over DC/AC 30V!

11. NCV sensing measurement

Measurement steps:

1) Turn the rotary switch to NCV position.
2) When the top-left corner marked with NCV closely contact the measured conductor or socket, the red NCV indicator flashes at a frequency of 3Hz and the buzzer beeps at a frequency of 3Hz.
3) LCD shows "EF" when no voltage is detected.

Figure 15

Warning:

• As the NCV detection judges whether there is voltage only through spatial electromagnetic field, the detected voltage is only for reference. It doesn't represent that there is no voltage in the conductor, even though the NCV measurement result is no voltage. Please do not judge whether there is voltage in the insulated/shielded conductor through NCV measurement result, as conductor or socket differs in type and design as well as insulation thickness, the detection result may be affected. The applicable frequency of induction voltage is 50Hz/60Hz.
  ● Grip the casing of the meter by hand when conducting NCV measurement.

12. Other functions

* Measurement result = displayed value – capacitance of open-circuit test leads. For capacitance ≤60nF, it is recommended to deduct the open circuit reading in REL mode.

* Accuracy guarantee: 5%\~100%

* For the range of 60mF, the measurement time is about 20s.

7. Flex clamp sensor measurement

Range	Resolution	Accuracy
30.00A	0.01A	±(0.8%+8)
300.0A	0.1A
3000A	1A

* Overload protection: 1000Vrms or 1000Vdc

* Frequency response: 45Hz\~400Hz

* The indicated accuracy represents the accuracy of the multimeter.

* When monitoring online frequency at AC current position, the requirement below must be satisfied: input amplitude ≥ range×10%

* Voltage-current relation:

a: 30A, 100mV(AC)=1A, start examination at 300mV, full-range scope (AC): 0.300V\~3.00V, OL will be displayed when the voltage is >3.1V.

b: 300A, 10mV(AC)=1A, start examination at 300mV, full-range scope (AC): 0.300V\~3.00V, OL will be displayed when the voltage is >3.1V.

c: 3000A, 1mV(AC)=1A, start examination at 300mV, full-range scope (AC): 0.300V\~3.00V, OL will be displayed when the voltage is >3.1V.

1. Frequency measurement

Range		Resolution	Accuracy
Frequency	60.00Hz~1.000MHz	0.01Hz~0.001MHz	±(0.08%+4)

* Frequency measurement scope: 10Hz\~1MHz. Not specified for >1MHz ≤99.99kHz: 200mVrms≤ input ≤20Vrms

99.99kHz\~1MHz: 600mVrms≤ input ≤20Vrms
1MHz: Not specified
* Overload protection: 1500Vrms or 1700Vdc.

XI. Maintenance

⚠ Warning: Before opening the rear cover or battery cover of the meter, switch off the power supply and remove the test leads.

1. General maintenance

• Clean the meter casing with a damp cloth and mild detergent. Do not use abrasives or solvents.
• If there is any malfunction, stop using the meter and send it for maintenance.
  ● The maintenance and service must be implemented by qualified professionals or designated departments.

2. Battery replacement (Figure 16)

" " is displayed, please replace the battery in time to ensure measurement accuracy.
