Sikkerhedsoplysninger

For at sikre sikker betjening og service af måleren skal du følge disse instruktioner. Manglende overholdelse af disse advarsler kan resultere i alvorlig personskade eller død.

• Always read and understand the entire instruction manual before using the meter.
• Overskrid ikke de maksimale inputgrænser for nogen funktion.
• Vær forsigtig, når du arbejder med voltagover 30V AC RMS, 42V peak eller 60V DC. Disse voluminertages udgør en stødfare.
• 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.
• Inspect test leads for damaged insulation or exposed metal before each use. Replace if damaged.
• Brug ikke måleren, hvis den ser beskadiget ud, eller hvis huset er åbent.
• Sørg for, at batteridækslet er forsvarligt lukket før brug.
• Adhere to local and national safety codes. Use personal protective equipment (PPE) such as approved safety glasses and electrically insulated gloves when necessary.

• mAμA: Positive input for milliampere og mikroamperestrømsmålinger.
• A: Positive input for amperestrømsmålinger.
• Knapper:
• VÆLGE: Toggles between functions on a single dial position (e.g., AC/DC voltage, diode/kontinuitet).
• RÆKKEVIDDE: Manually selects measurement range or returns to auto-ranging.
• △: Delta function for relative measurements.
• HOLDE: Fryser den aktuelle displayaflæsning.

Opsætning

Installation af batteri

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.

Tilslutning af prøveledninger

Always ensure test leads are properly connected before taking measurements.

1. Indsæt den sorte testledning i KOM (fælles) indgangsstik.
2. Insert the red test lead into the appropriate positive input jack based on the measurement you intend to make:
• For bdtage, resistance, capacitance, or frequency, use the VΩHz stik.
• For milliampere or microampere current, use the mAμA stik.
• For ampere current, use the A stik.
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.

Betjeningsvejledning

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

Måling AC/DC Voltage

1. Set the function selector to V~ (AC Voltage) eller V- (DC-volumentage). Use the SELECT button to toggle if both are on one position.
2. Tilslut den sorte testledning til KOM og den røde testledning til VΩHz.
3. Connect the test probes in parallel across the circuit or component to be measured.
4. Læs bindtage -værdi på displayet.

Måling af AC/DC-strøm

Vigtig: Current measurements require the meter to be connected in series with the circuit. Ensure the circuit is de-energized before connecting the meter.

1. Sluk for kredsløbet.
2. Set the function selector to A~ (AC Current) or A- (DC Current), or mA~ / mA-.
3. Tilslut den sorte testledning til KOMTilslut den røde testledning til 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. Genstart kredsløbet og aflæs strømværdien.
6. De-energize the circuit before disconnecting the meter.

Measuring Resistance (Ω)

1. De-energize the circuit or component.
2. Set the function selector to Ω.
3. Tilslut den sorte testledning til KOM og den røde testledning til VΩHz.
4. Tilslut testproberne på tværs af komponenten.
5. Read the resistance value.

Measuring Capacitance (CAP)

1. Sørg for, at kondensatoren er helt afladet før måling.
2. Set the function selector to CAP.
3. Tilslut den sorte testledning til KOM og den røde testledning til VΩHz.
4. Tilslut testproberne på tværs af kondensatorterminalerne.
5. Aflæs kapacitansværdien.

Measuring Frequency (Hz)

1. Set the function selector to Hz.
2. Tilslut den sorte testledning til KOM og den røde testledning til VΩHz.
3. Tilslut testproberne på tværs af signalkilden.
4. Read the frequency value.

Kontinuitetstest

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. Tilslut den sorte testledning til KOM og den røde testledning til VΩHz.
4. Connect the test probes across the circuit path or component.
5. En biplyd indikerer kontinuitet (lav modstand). Displayet viser modstandsværdien.

Opretholdelse

Rensning

Tør måleren af ​​med reklameamp klud og mildt rengøringsmiddel. Brug ikke slibemidler eller opløsningsmidler. Sørg for, at måleren er helt tør før brug.

Udskiftning af batteri

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.
