Varnostne informacije

Za zagotovitev varnega delovanja in servisiranja števca upoštevajte ta navodila. Neupoštevanje teh opozoril lahko povzroči hude telesne poškodbe ali smrt.

• Always read and understand the entire instruction manual before using the meter.
• Ne prekoračite največjih vhodnih omejitev za nobeno funkcijo.
• Bodite previdni pri delu z voltagnad 30 V AC RMS, 42 V vrhom ali 60 V DC. Te vol.tagpredstavljajo nevarnost električnega udara.
• Always use the proper terminals, function, and range for your measurements. The DM-810A features a Beep-Jack audible and visible warning to guard against improper A and mA terminal plug-in.
• Pred vsako uporabo preverite merilne kable za morebitne poškodbe izolacije ali izpostavljene kovine. Če so poškodovani, jih zamenjajte.
• Merilnika ne uporabljajte, če je videti poškodovan ali če je ohišje odprto.
• Pred uporabo se prepričajte, da je pokrov baterije varno zaprt.
• Adhere to local and national safety codes. Use personal protective equipment (PPE) such as approved safety glasses and electrically insulated gloves when necessary.

• mAμA: Pozitiven vhod za miliamptukaj in mikroamptrenutne meritve.
• A: Positive input for amptrenutne meritve.
• Gumbi:
• IZBERI: Toggles between functions on a single dial position (e.g., AC/DC voltage, dioda/kontinuiteta).
• OBMOČJE: Manually selects measurement range or returns to auto-ranging.
• △: Delta function for relative measurements.
• DRŽI: Zamrzne trenutno odčitavanje na zaslonu.

Nastavitev

Namestitev baterije

The Greenlee DM-810A requires batteries for operation. Refer to the back of the meter for the battery compartment. Use a screwdriver to open the compartment, insert the specified batteries (typically AA or 9V, check the compartment label), observing correct polarity, and then securely close the cover.

Priključitev testnih potencialnih strank

Always ensure test leads are properly connected before taking measurements.

1. Črni testni kabel vstavite v COM (skupni) vhodni priključek.
2. Insert the red test lead into the appropriate positive input jack based on the measurement you intend to make:
• Za voltage, resistance, capacitance, or frequency, use the VΩHz jack.
• Za miliampere or microampere current, use the mAμA jack.
• Za ampere current, use the A jack.
3. The meter's Beep-Jack feature will provide an audible and visible alert if the function selector is set to a current measurement (A or mA) but the test lead is incorrectly plugged into a voltage/resistance jack, or vice-versa. This helps prevent damage to the meter and ensures correct setup.

Navodila za uporabo

This section details how to perform various measurements with your DM-810A multimeter.

Merjenje AC/DC Voltage

1. Set the function selector to V~ (AC Voltage) ali V- (DC Voltage). Use the SELECT button to toggle if both are on one position.
2. Priključite črni preskusni kabel na COM in rdeči testni kabel do VΩHz.
3. Merilne sonde priključite vzporedno na vezje ali komponento, ki jo želite izmeriti.
4. Preberite zvtage vrednost na zaslonu.

Merjenje AC/DC toka

Pomembno: Za meritve toka mora biti merilnik zaporedno priključen na tokokrog. Pred priključitvijo merilnika se prepričajte, da je tokokrog izklopljen.

1. Odklopite tokokrog.
2. Set the function selector to A~ (AC Current) or A- (DC Current), or mA~ / mA-.
3. Priključite črni preskusni kabel na COM. Connect the red test lead to mAμA for small currents or A for larger currents (up to 10A). The Beep-Jack warning will activate if leads are in the wrong jacks for the selected function.
4. Open the circuit where the current is to be measured and connect the meter in series.
5. Ponovno vklopite vezje in odčitajte trenutno vrednost.
6. De-energize the circuit before disconnecting the meter.

Merjenje upornosti (Ω)

1. De-energize the circuit or component.
2. Set the function selector to Ω.
3. Priključite črni preskusni kabel na COM in rdeči testni kabel do VΩHz.
4. Merilne sonde priključite na komponento.
5. Odčitajte vrednost upora.

Measuring Capacitance (CAP)

1. Pred meritvijo se prepričajte, da je kondenzator popolnoma izpraznjen.
2. Set the function selector to CAP.
3. Priključite črni preskusni kabel na COM in rdeči testni kabel do VΩHz.
4. Merilne sonde priključite na priključke kondenzatorja.
5. Read the capacitance value.

Measuring Frequency (Hz)

1. Set the function selector to Hz.
2. Priključite črni preskusni kabel na COM in rdeči testni kabel do VΩHz.
3. Merilne sonde priključite na vir signala.
4. Read the frequency value.

Test kontinuitete

1. De-energize the circuit or component.
2. Set the function selector to the continuity symbol (often shared with diode test, use SELECT to toggle).
3. Priključite črni preskusni kabel na COM in rdeči testni kabel do VΩHz.
4. Connect the test probes across the circuit path or component.
5. Zvočni pisk označuje prevodnost (nizek upor). Na zaslonu se bo prikazala vrednost upora.

Vzdrževanje

Čiščenje

Obrišite števec z oglasomamp krpo in blagim detergentom. Ne uporabljajte abrazivnih sredstev ali topil. Pred uporabo se prepričajte, da je merilnik popolnoma suh.

Zamenjava baterije

When the battery indicator appears on the display, replace the batteries immediately to ensure accurate readings. Follow the battery installation steps outlined in the Setup section.

Zamenjava varovalke

If the current measurement functions cease to work, the internal fuses may need replacement. Refer to the meter's internal diagram (usually accessible by opening the battery compartment or back casing) for fuse specifications and replacement instructions. Always replace fuses with those of the specified type and rating to maintain safety and performance.
