4. Configuració

4.1 Instal·lació de la bateria

The multimeter requires batteries for operation. 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 de la unitat.
3. Utilitzeu un tornavís per obrir la coberta.
4. Insert new batteries, observing correct polarity (+/-).
5. Substituïu la tapa del compartiment de la bateria i fixeu-la.

4.2 Connexió dels cables de prova

For most measurements, connect the black test lead to the "COM" jack and the red test lead to the appropriate input jack based on the measurement type.

• Black Lead: Always connect to the COM Jack (comú).
• Red Lead:
  • Per al voltage (V), Resistance (Ω), Capacitance (μF), Diode, Continuity, Frequency (Hz): Connect to the VΩHz jack.
  • For Current (mA): Connect to the mA jack.
  • For High Current (10A): Connect to the 10A jack.

5. Instruccions de funcionament

The RICHMETERS 404A features auto-ranging for most functions, simplifying operation.

Figure 5.1: Measurement Functions. This image illustrates the various measurement capabilities of the multimeter, including AC Voltage, DC Voltage, Frequency, Resistance, Capacitance, Diode, Data Hold, Backlight, Continuity, AC Current, DC Current, Auto Power Off, and Capacitance.

5.1 Passos bàsics de mesura

1. Connect the test leads correctly as described in Section 4.2.
2. Turn the Rotary Switch to the desired measurement function.
3. If multiple functions are available on one rotary switch position (e.g., AC/DC Voltage), press the SEL botó per anar-hi ciclant.
4. Connect the test probes to the circuit or component under test.
5. Llegiu el valor de mesura a la pantalla LCD.

5.2 Funcions de mesura específiques

• Voltage Measurement (AC/DC V): Turn the rotary switch to 'V'. Use the SEL button to switch between AC and DC voltage. Connect probes in parallel with the circuit.
• Current Measurement (AC/DC A/mA): Turn the rotary switch to 'A' or 'mA'. Use the SEL button to switch between AC and DC current. Connect probes in series with the circuit. Ensure correct input jack (10A or mA).
• Resistance Measurement (Ω): Turn the rotary switch to 'Ω'. Connect probes across the component. Ensure the circuit is de-energized.
• Capacitance Measurement (μF): Turn the rotary switch to 'μF'. Connect probes across the capacitor. Ensure the capacitor is discharged before testing.
• Prova de díode: Turn the rotary switch to the diode symbol. Connect the red probe to the anode and the black probe to the cathode. The display shows the forward voltage drop. Reverse the probes to check for open circuit.
• Prova de continuïtat: Turn the rotary switch to the continuity symbol. If resistance is below a certain threshold, the buzzer will sound.
• Mesura de freqüència (Hz): Turn the rotary switch to 'Hz'. Connect probes to the signal source.
• Vol. Sense contactetage (NCV): Turn the rotary switch to 'NCV'. Bring the top of the meter near a live AC voltagfont electrònica. El mesurador indicarà la presència de voltatge de CAtagi sense contacte directe.

5.3 Característiques especials

• Conservació de dades: Premeu el botó HOLD/* button briefly to freeze the current reading on the display. Press again to release.
• Il·luminació de fons: Manteniu premut el botó HOLD/* button to turn the display backlight on or off. This is useful for operation in dark environments.
