Introducció

The Irfora AN113D is a compact and versatile digital multimeter designed for accurate measurement of various electrical parameters. Featuring 6000 counts, True RMS capability, and auto-ranging, it is suitable for both professional and DIY electrical tasks. This meter can measure DC/AC voltage, DC/AC current, resistance, capacitance, frequency, duty cycle, diode, continuity, and temperature.

This manual provides detailed instructions for the safe and effective use of your AN113D Digital Multimeter. Please read it thoroughly before operation and retain it for future reference.

Configuració

1. Desembalatge

Carefully remove the multimeter and all accessories from the packaging. Verify that all components are present:

  • AN113D Digital Multimeter
  • Cables de prova (vermell i negre)
  • Thermocouple (K-type)
  • Manual d'usuari

Inspect the device for any signs of damage. If any damage is found, do not use the device and contact your supplier.

2. Instal·lació de la bateria

The AN113D multimeter typically requires 2x AAA batteries (not always included). To install or replace batteries:

  1. Assegureu-vos que el multímetre estigui apagat i que els cables de prova estiguin desconnectats.
  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 the batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
  5. Substituïu la tapa del compartiment de la bateria i fixeu-la amb el cargol.

Note: Remove batteries if the meter is not to be used for an extended period to prevent leakage.

3. Connexió dels cables de prova

Always connect the test leads correctly for accurate and safe measurements:

  • Inseriu el negre test lead into the "COM" (Common) jack.
  • Inseriu el vermell test lead into the "VΩmA" jack for voltage, resistance, continuity, diode, capacitance, frequency, and small current measurements.
  • For large current measurements (e.g., 10A), insert the vermell test lead into the "10A" jack (if available on your model).

Warning: Ensure test leads are fully inserted before taking measurements.

Instruccions de funcionament

The AN113D features an intuitive rotary switch for selecting measurement functions and an LCD display for reading values.

1. Encendre/apagar

Turn the rotary switch from the "OFF" position to any desired measurement function to power on the multimeter. To power off, turn the rotary switch back to the "OFF" position.

2. Auto-Ranging Function

The AN113D is an auto-ranging multimeter, meaning it automatically selects the appropriate measurement range for the input signal. This simplifies operation as you do not need to manually select ranges.

3. Mides bàsiques

a. DC VoltagMesura e (V–)

  1. Turn the rotary switch to the "V–" position.
  2. Connecteu el cable de prova vermell al costat positiu (+) del circuit i el cable de prova negre al costat negatiu (-).
  3. Llegeix el voltage valor a la pantalla LCD.

b. AC VoltagMesura de e (V~)

  1. Gireu l'interruptor rotatiu a la posició "V~".
  2. Connecteu els cables de prova a través del voltatge de CAtage font.
  3. Llegeix el voltage valor a la pantalla LCD.

c. Resistance Measurement (Ω)

  1. Gireu l'interruptor rotatiu a la posició "Ω".
  2. Assegureu-vos que el circuit o component estigui desenergitzat abans de mesurar la resistència.
  3. Connecteu els cables de prova al component que s'ha de mesurar.
  4. Llegiu el valor de la resistència a la pantalla LCD.

d. Continuity Test (♫)

  1. Turn the rotary switch to the "♫" (Continuity/Diode) position.
  2. Connecteu els cables de prova a través del circuit o component.
  3. If the resistance is below a certain threshold (typically 50Ω), the meter will emit an audible beep, indicating continuity.

e. Diode Test (▲)

  1. Turn the rotary switch to the "▲" (Continuity/Diode) position.
  2. Connecteu el cable de prova vermell a l'ànode i el cable de prova negre al càtode del díode.
  3. La pantalla mostrarà el volum d'avançtage drop. Reverse the leads to check for open circuit (OL) in reverse bias.

f. Temperature Measurement (°C/°F)

  1. Turn the rotary switch to the "TEMP" position.
  2. Connect the K-type thermocouple to the appropriate input jacks (usually marked for temperature).
  3. Col·loqueu la punta del termopar sobre o a prop de l'objecte la temperatura del qual es vol mesurar.
  4. Llegiu el valor de la temperatura a la pantalla LCD.

4. Funcions especials

a. Data Hold (HOLD)

Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold function.

b. Llum de fons

Press the backlight button (often combined with HOLD or a separate button) to illuminate the display for better visibility in low-light conditions. Press again to turn off.

Manteniment

Proper maintenance ensures the longevity and accuracy of your AN113D Digital Multimeter.

1. Neteja

Netegeu el cas amb l'anunciamp drap i un detergent suau. No utilitzeu abrasius ni dissolvents. Assegureu-vos que el mesurador estigui completament sec abans d'utilitzar-lo.

2. Substitució de la bateria

When the battery indicator appears on the display, replace the batteries as described in the "Battery Installation" section under Setup. Low battery can affect measurement accuracy.

3. Substitució de fusibles

If the current measurement function stops working, the fuse may be blown. Refer to the specifications for the correct fuse type and rating. To replace the fuse:

  1. Ensure the multimeter is off and test leads are disconnected.
  2. Obriu la tapa del compartiment de la bateria.
  3. Locate the fuse holder (may be near the battery compartment or require opening the main case).
