4. Nastavitev

4.1 Namestitev baterije

The MS8233B requires 2 LR44 batteries for operation. Ensure the batteries are installed correctly before first use or when replacing them.

1. Turn off the multimeter and disconnect all test leads.
2. Poiščite predal za baterije na zadnji strani merilnika.
3. Z izvijačem odprite pokrov predalčka za baterije.
4. Vstavite 2 bateriji LR44 in pri tem upoštevajte pravilno polarnost (+ in -).
5. Ponovno namestite pokrov prostora za baterije in ga pritrdite z vijakom.

5. Navodila za uporabo

Before taking any measurements, ensure the test leads are properly connected to the meter and the circuit under test.

5.1 Splošno delovanje

1. Turn the rotary switch from the "OFF" position to the desired measurement function.
2. Connect the test leads to the appropriate input jacks and the circuit.
3. Izmerjeno vrednost odčitajte na LCD-zaslonu.
4. To turn off the meter, rotate the switch back to the "OFF" position.

5.2 DC zvtagMeritev (V-)

• Vrtljivo stikalo nastavite na želeno glasnost enosmernega tokatage-območje (npr. 200 mV, 2 V, 20 V, 200 V, 600 V).
• Priključite rdeči testni kabel na vtičnico VΩmA in črni preskusni kabel na vtičnico COM.
• Merilne kable priključite na komponento ali vezje, ki ga želite izmeriti.

5.3 AC VoltagMeritev (V~)

• Vrtljivo stikalo nastavite na želeno glasnost izmeničnega tokatagobmočju (npr. 200 V, 600 V).
• Priključite rdeči testni kabel na vtičnico VΩmA in črni preskusni kabel na vtičnico COM.
• Priključite merilne kable na izmenični tok (AC volt)tage vir.

5.4 DC Current Measurement (A-)

• Vrtljivo stikalo nastavite na želeno območje enosmernega toka (npr. 200 µA, 2 mA, 20 mA, 200 mA, 10 A).
• For currents up to 200mA, connect the red test lead to the VΩmA jack. For currents up to 10A, connect the red test lead to the 10A jack. Always connect the black test lead to the COM jack.
• Connect the meter in series with the circuit to measure the current.
• Pozor: Do not attempt to measure currents exceeding 200mA through the VΩmA jack or 10A through the 10A jack.

5.5 Merjenje upornosti (Ω)

• Vrtljivo stikalo nastavite na želeno območje upora (npr. 200 Ω, 2 kΩ, 20 kΩ, 200 kΩ, 2 MΩ).
• Priključite rdeči testni kabel na vtičnico VΩmA in črni preskusni kabel na vtičnico COM.
• Connect the test leads across the resistor or component to be measured. Ensure the circuit is de-energized.

5.6 Preskus diode

• Set the rotary switch to the Diode symbol.
• Priključite rdeči testni kabel na vtičnico VΩmA in črni preskusni kabel na vtičnico COM.
• Rdeči merilni kabel priključite na anodo, črni pa na katodo diode. Na zaslonu se bo prikazala napetost v smeri naprej.tage padec.
• Reverse the leads. An open circuit (OL) reading indicates a good diode. A reading in both directions or no reading indicates a faulty diode.

5.7 Preizkus kontinuitete

• Set the rotary switch to the Continuity symbol.
• Priključite rdeči testni kabel na vtičnico VΩmA in črni preskusni kabel na vtičnico COM.
• Connect the test leads across the circuit or component. If the resistance is less than approximately 60Ω, the buzzer will sound, indicating continuity.

5.8 Merjenje temperature

While the product title mentions temperature, the MS8233B model's detailed specifications do not explicitly list a temperature function. If your specific unit includes this feature, typically you would:

• Set the rotary switch to the Temperature function (usually marked with °C or °F).
• Connect a K-type thermocouple (if included) to the VΩmA and COM jacks, observing polarity.
• Place the thermocouple probe at the point where temperature needs to be measured.

5.9 Funkcija zadrževanja podatkov

• Press the "HOLD" button to freeze the current reading on the display.
• Press the "HOLD" button again to release the reading and resume live measurements.

5.10 Funkcija osvetlitve ozadja
