4. Configuració

4.1 Instal·lació de la bateria

The ANENG ST181 requires two AAA batteries for operation. To install or replace batteries:

1. Assegureu-vos que el multímetre estigui apagat.
2. Localitzeu la tapa del compartiment de la bateria a la part posterior del dispositiu.
3. Utilitzeu un tornavís per obrir el compartiment de la bateria.
4. Insert two AAA batteries, observing the correct polarity (+/-).
5. Tanqueu la tapa del compartiment de la bateria i fixeu-la amb el cargol.

5. Instruccions de funcionament

This section details how to perform various measurements using your ANENG ST181 Clamp Multímetre.

5.1 Mesura de corrent altern

El clamp jaw allows for non-contact measurement of AC current up to 400A. The maximum diameter of the wire that can be measured is 1.42 inches (36mm).

1. Turn the function dial to the 'A~' position.
2. Obriu el clamp mandíbula prement la palanca.
3. Enclose a single conductor (not a bundle of wires) within the clamp mandíbula.
4. Ensure the jaw is fully closed.
5. Llegiu el valor del corrent altern a la pantalla.

5.2 AC/DC Voltage Mesura

Per mesurar AC o DC voltage:

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'INPUT' jack.
2. Turn the function dial to the 'V~' for AC voltage o 'V=' per a vol DCtage. The meter will automatically select the appropriate range.
3. Connecteu les sondes de prova al circuit o component que s'ha de mesurar.
4. Llegeix el voltage valor a la pantalla.

5.3 Mesura de la Resistència

Per mesurar la resistència:

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'INPUT' jack.
2. Turn the function dial to the 'Ω' position.
3. Connect the test probes across the component to be measured. Ensure the circuit is de-energized.
4. Llegiu el valor de resistència a la pantalla.

5.4 Mesura de la capacitat

Per mesurar la capacitat:

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'INPUT' jack.
2. Turn the function dial to the 'Capacitance' symbol.
3. Connect the test probes across the capacitor. Ensure the capacitor is discharged before testing.
4. Llegiu el valor de la capacitat a la pantalla.

5.5 Prova de continuïtat

Per comprovar la continuïtat:

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'INPUT' jack.
2. Turn the function dial to the 'Continuity' symbol (often shared with resistance or diode).
3. Connecteu les sondes de prova a través del circuit o component.
4. If there is continuity (low resistance), the meter will emit an audible beep.

5.6 Prova de díodes

Per provar un díode:

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'INPUT' jack.
2. Turn the function dial to the 'Diode' symbol.
3. Connecteu la sonda de prova vermella a l'ànode i la sonda de prova negra al càtode del díode.
4. Llegeix el vol endavanttage drop on the display. Reverse the probes; the display should show 'OL' (open loop) for a good diode.

5.7 Vol. sense contactetage (NCV) Detecció

La funció NCV permet la detecció ràpida del volum de CAtagi sense contacte directe.

1. Turn the function dial to the 'NCV' position or press the NCV button if available in other modes.
2. Move the top end of the multimeter near the conductor or outlet.
3. The meter will emit an audible beep and the NCV indicator light will flash if AC voltage is detected. The frequency of beeps and flashes increases with stronger voltage.

5.8 Frequency (Hz) Measurement

Per mesurar la freqüència:

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'INPUT' jack.
2. Turn the function dial to the 'Hz' position (often shared with voltage o actual).
3. Connect the test probes across the circuit where frequency needs to be measured.
4. Llegiu el valor de la freqüència a la pantalla.

5.9 Live/Neutral Line Detection

This function helps identify live and neutral wires.

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'INPUT' jack.
2. Turn the function dial to the 'Live/Zero' position (if available, or use NCV for live wire detection).
3. Touch the red test probe to the wire. If it's a live wire, the meter will indicate it (e.g., with a specific symbol or sound).

6. Manteniment

6.1 Neteja

Netegeu el comptador amb anuncisamp drap i detergent suau. No utilitzeu abrasius ni dissolvents. Assegureu-vos que el mesurador estigui sec abans d'utilitzar-lo.

6.2 Emmagatzematge

When not in use for extended periods, remove the batteries to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.

6.3 Substitució de la bateria
