4.1 Instalación da batería

The PM8250 requires four 1.5V AA batteries for operation. To install or replace batteries:

1. Asegúrese de que o multímetro estea apagado e que os cables de proba estean desconectados.
2. Localice a tapa do compartimento das baterías na parte traseira do medidor.
3. Desaparafuse o(s) parafuso(s) de suxeición e retire a tapa.
4. Insert four 1.5V AA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Volva colocar a tapa do compartimento da batería e asegúreaa co(s) parafuso(s).

4.2 Conexión dos cables de proba

Connect the test leads to the appropriate input jacks for your desired measurement:

• Insira o cable de proba negro no COM Jack (común).
• Para o voltage, resistance, capacitance, frequency, diode, continuity, and temperature measurements, insert the red test lead into the VΩHzTemp jack.
• Para medicións de corrente de ata 600 mA, insira a punta de proba vermella no mA jack.
• For current measurements up to 10A, insert the red test lead into the 10A jack (if applicable, refer to meter markings).

5. Instrucións de funcionamento

To operate the multimeter, turn the rotary switch to the desired function. The meter will typically default to auto-ranging. Press the 'RANGE' button to switch between auto and manual ranging if needed.

5.1 DC VoltagMedición de e (V–)

Para medir DC voltage, including high voltage PV systems:

1. Poña o interruptor rotativo en V– position (1700V range).
2. Conecte os cables de proba en paralelo ao circuíto ou compoñente que se está a probar.
3. Le o voltago valor da pantalla.

5.2 AC VoltagMedición de e (V∼)

Para medir AC voltage:

1. Poña o interruptor rotativo en V∼ posición.
2. Connect the test leads in parallel to the AC source.
3. Le o voltago valor da pantalla.
4. Preme o LPF button to activate the Low Pass Filter for measurements in noisy environments (e.g., VFD outputs).

5.3 Medición de resistencia (Ω)

Para medir a resistencia:

1. Poña o interruptor rotativo en Ω posición.
2. Ensure the circuit is de-energized before connecting the test leads across the component.
3. Lea o valor de resistencia na pantalla.

5.4 Current Measurement (mA/A)

To measure DC or AC current:

1. Poña o interruptor rotativo en mA or A posición. Usa o FUNC button to select AC or DC current.
2. Connect the test leads in series with the circuit. Ensure the correct input jack (mA or 10A) is used.
3. Lea o valor actual na pantalla.
