5. Configuración
5.1 Battery Installation (Multimeter)
The multimeter is battery-driven. To install or replace batteries:
- Asegúrese de que o multímetro estea apagado.
- Localiza a tapa do compartimento da batería na parte traseira do dispositivo.
- Desaparafuse o(s) parafuso(s) de suxeición e retire a tapa.
- Insert new batteries, observing correct polarity (+/-). Refer to the markings inside the compartment.
- Replace the cover and secure it with the screw(s).
5.2 Conexión dos cables de proba
For most measurements, connect the test leads as follows:
- Insira o cable de proba negro na toma "COM" (común).
- Insert the red test lead into the "VΩmA" jack for voltage, resistance, and current measurements up to 200mA.
- Para medicións de corrente alta (ata 10 A), insira a punta de proba vermella na toma "10 A".

6. Instrucións de funcionamento
6.1 Encendido/apagado
Rotate the rotary switch to any measurement function to turn the multimeter ON. To turn it OFF, rotate the switch to the "OFF" position.
6.2 Medir Vol. CCtage (VDC)
- Connect the test leads as described in Section 5.2 (red to VΩmA, black to COM).
- Rotate the rotary switch to the desired "VDC" range (e.g., 20V, 200V, 600V). If unsure, start with the highest range and decrease as needed.
- Conecte as sondas de proba en paralelo ao circuíto ou compoñente que desexe medir.
- Le o voltago valor da pantalla.
6.3 Medición AC Voltage (VAC)
- Connect the test leads as described in Section 5.2 (red to VΩmA, black to COM).
- Rotate the rotary switch to the desired "VAC" range (e.g., 200V, 600V).
- Connect the test probes in parallel to the AC source.
- Le o voltago valor da pantalla.
6.4 Medición da resistencia (Ω)
- Asegúrese de que o circuíto estea desenergizado antes de medir a resistencia.
- Connect the test leads as described in Section 5.2 (red to VΩmA, black to COM).
- Rotate the rotary switch to the desired "Ω" range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
- Connect the test probes across the component whose resistance you want to measure.
- Lea o valor de resistencia na pantalla.
6.5 Battery Testing (1.5V / 9V)
- Connect the test leads as described in Section 5.2 (red to VΩmA, black to COM).
- Rotate the rotary switch to the "1.5V BATT." or "9V BATT." position.
- Connect the red probe to the positive (+) terminal of the battery and the black probe to the negative (-) terminal.
- Ler a batería voltage na pantalla.
6.6 Using the Non-Contact AC Voltage Tester (MS-430)
The MS-430 is designed to detect AC voltage without direct contact, providing a quick safety check.
- Press the power button on the MS-430 to turn it on.
- Bring the tip of the tester close to the wire or outlet you suspect has AC voltage.
- Se AC voltage is detected, the tester will emit an audible beep and/or a visual indicator (LED) will light up.
- Prema de novo o botón de acendido para apagalo.
