Ohutusteave
Mõõturi ohutu töö ja hoolduse tagamiseks järgige neid juhiseid. Nende hoiatuste eiramine võib põhjustada raskeid vigastusi või surma.
- Always read and understand the entire instruction manual before using the meter.
- Ärge ületage ühegi funktsiooni maksimaalset sisendvõimsuse piirangut.
- Olge voldiga töötades ettevaatliktagüle 30 V vahelduvpinge RMS, 42 V tipp või 60 V alalispinge. Need pingedtagsee kujutab endast šokiohtu.
- 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.
- Enne iga kasutuskorda kontrollige testjuhtmeid kahjustatud isolatsiooni või paljastunud metalli suhtes. Kui need on kahjustatud, vahetage need välja.
- Ärge kasutage mõõturit, kui see tundub kahjustatud või kui korpus on avatud.
- Enne kasutamist veenduge, et aku kate on kindlalt suletud.
- Adhere to local and national safety codes. Use personal protective equipment (PPE) such as approved safety glasses and electrically insulated gloves when necessary.

Seadistamine
Aku paigaldamine
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.
Testjuhtmete ühendamine
Always ensure test leads are properly connected before taking measurements.
- Sisestage must testjuhe pessa KOM (tavaline) sisendpesa.
- Insert the red test lead into the appropriate positive input jack based on the measurement you intend to make:
- Vol. Jaokstage, resistance, capacitance, or frequency, use the VΩHz tungraua.
- Milli kohtaampere or microampere current, use the mAμA tungraua.
- Sest ampere current, use the A tungraua.
- 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.
Kasutusjuhised
This section details how to perform various measurements with your DM-810A multimeter.

Mõõtmine AC/DC Voltage
- Set the function selector to V~ (AC Voltage) või V- (alalisvoolu mahttage). Use the SELECT button to toggle if both are on one position.
- Ühendage must proovikaabel KOM ja punane testjuhe VΩHz.
- Ühendage testsondid paralleelselt mõõdetava vooluringi või komponendiga.
- Lugege kdtage väärtus ekraanil.
AC/DC voolu mõõtmine
Tähtis: Current measurements require the meter to be connected in series with the circuit. Ensure the circuit is de-energized before connecting the meter.
- Lülitage vooluring välja.
- Set the function selector to A~ (AC Current) or A- (DC Current), or mA~ / mA-.
- Ühendage must proovikaabel KOM. 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.
- Open the circuit where the current is to be measured and connect the meter in series.
- Lülitage vooluring uuesti sisse ja lugege voolutugevuse väärtus.
- De-energize the circuit before disconnecting the meter.
Measuring Resistance (Ω)
- De-energize the circuit or component.
- Set the function selector to Ω.
- Ühendage must proovikaabel KOM ja punane testjuhe VΩHz.
- Ühendage testsondid komponendiga.
- Loe takistuse väärtust.
Measuring Capacitance (CAP)
- Enne mõõtmist veenduge, et kondensaator on täielikult tühjenenud.
- Set the function selector to CAP.
- Ühendage must proovikaabel KOM ja punane testjuhe VΩHz.
- Ühendage testsondid kondensaatori klemmidega.
- Loe mahtuvuse väärtus.
Measuring Frequency (Hz)
- Set the function selector to Hz.
- Ühendage must proovikaabel KOM ja punane testjuhe VΩHz.
- Ühendage testsondid signaaliallikaga.
- Loe sageduse väärtust.
Järjepidevuse test
- De-energize the circuit or component.
- Set the function selector to the continuity symbol (often shared with diode test, use SELECT to toggle).
- Ühendage must proovikaabel KOM ja punane testjuhe VΩHz.
- Ühendage testsondid vooluringi tee või komponendi külge.
- An audible beep indicates continuity (low resistance). The display will show the resistance value.
Hooldus
Puhastamine
Pühkige arvesti reklaamigaamp lapiga ja õrna pesuvahendiga. Ärge kasutage abrasiivseid aineid ega lahusteid. Enne kasutamist veenduge, et mõõteseade on täiesti kuiv.
