3. Įdėkite dvi AAA tipo baterijas, laikydamiesi teisingo poliškumo (+ ir -), kaip nurodyta skyrelio viduje.
4. Uždėkite akumuliatoriaus skyriaus dangtelį ir pritvirtinkite jį varžtu.

4.2. Bandymo laidų prijungimas

Proper connection of test leads is essential for accurate and safe measurements.

• Įkiškite juodą bandymo laidą į „COM“ (bendrąjį) lizdą.
• Daugumai tūriųtage, resistance, and continuity measurements, insert the red test lead into the "VΩmA" jack.
• For high current (up to 10A DC) measurements, insert the red test lead into the "10A DC" jack. Ensure the function dial is set to the appropriate current range.

5. Naudojimo instrukcijos

The Sealey MM20HV offers 8 functions for various electrical measurements.

5.1. Maitinimo įjungimas/išjungimas

Rotate the central function dial from the "OFF" position to any desired measurement function to turn the multimeter on. To turn off, rotate the dial back to "OFF".

5.2. Nuolatinės srovės įtampos matavimastage (V=)

1. Insert the black lead into the "COM" jack and the red lead into the "VΩmA" jack.
2. Set the function dial to the desired DC Voltage diapazonas (pvz., 200 mV, 2 V, 20 V, 200 V, 600 V). Jei tūriotage is unknown, start with the highest range and decrease as necessary.
3. Prijunkite bandymo zondus prie matuojamo komponento arba grandinės.
4. Perskaitykite ttage reikšmė LCD ekrane.

5.3. Matavimas AC Voltage (V~)

1. Insert the black lead into the "COM" jack and the red lead into the "VΩmA" jack.
2. Set the function dial to the desired AC Voltage range (e.g., 200V, 600V).
3. Prijunkite bandymo zondus prie kintamosios srovės įtampostage šaltinis.
4. Perskaitykite ttage reikšmė LCD ekrane.

5.4. Measuring DC Current (A=)

Atsargiai: Niekada nejunkite multimetro lygiagrečiai su įtampos matuokliutage source when measuring current. Always connect in series with the load.

1. Insert the black lead into the "COM" jack.
2. For currents up to 200mA, insert the red lead into the "VΩmA" jack. For currents up to 10A, insert the red lead into the "10A DC" jack.
3. Set the function dial to the appropriate DC Current range (e.g., 2mA, 20mA, 200mA, 10A).
4. Atidarykite grandinę, kurioje matuojama srovė, ir prijunkite multimetrą nuosekliai.
5. Skaitykite dabartinę vertę LCD ekrane.

5.5. Measuring Resistance (Ω)

Įspėjimas: Prieš matuodami varžą, įsitikinkite, kad grandinėje nėra įtampos ir visi kondensatoriai yra iškrauti.

1. Insert the black lead into the "COM" jack and the red lead into the "VΩmA" jack.
2. Set the function dial to the desired Resistance range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
3. Connect the test probes across the component whose resistance is to be measured.
4. Nuskaitykite varžos vertę LCD ekrane.

This function allows for quick checks of circuit continuity with an audible tone.

1. Insert the black lead into the "COM" jack and the red lead into the "VΩmA" jack.
2. Set the function dial to the continuity symbol (often shared with diode test).
3. Prijunkite bandymo zondus prie grandinės arba komponento.
4. An audible tone indicates continuity (low resistance). The display will show the resistance value.

5.7. Diode/Transistor Verification

This function allows for testing diodes and transistors.

1. Insert the black lead into the "COM" jack and the red lead into the "VΩmA" jack.
2. Set the function dial to the diode symbol.
3. For diode testing, connect the red probe to the anode and the black probe to the cathode. The display will show the forward voltage kritimas. Apkeiskite zondus; ekrane turėtų būti rodoma „OL“ (atvira kilpa), tai reiškia, kad diodas veikia gerai.
4. For transistor (hFE) testing, insert the transistor leads into the appropriate NPN or PNP sockets on the multimeter. The display will show the hFE value.

5.8. Measuring Temperature (°C)

The multimeter includes a thermocouple for temperature measurements.

1. Remove the test leads from the input jacks.
2. Insert the thermocouple plug into the "VΩmA" and "COM" jacks, observing polarity if indicated.
3. Set the function dial to the "°C" range.
4. Place the tip of the thermocouple on or near the object whose temperature is to be measured.
5. Read the temperature value in Celsius on the LCD display.

5.9. Duomenų laikymo funkcija

Press the "HOLD" button (typically a green button on the front panel) to freeze the current reading on the display. Press it again to release the hold and resume live readings.

6. Priežiūra

6.1. Valymas

Nuvalykite dėklą su skelbimuamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is off and disconnected from any circuits before cleaning.

6.2. Baterijos keitimas

When the battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use fresh AAA batteries.

6.3. Saugiklio keitimas

If the current measurement function stops working, the fuse may need replacement.

1. Įsitikinkite, kad multimetras yra išjungtas ir visi bandymo laidai yra atjungti.
2. Remove the battery compartment cover and batteries.
3. Locate the fuse(s) inside the compartment. The MM20HV typically uses a 200mA/250V fast-blow fuse for the mA range and a 10A/250V fast-blow fuse for the 10A range.
4. Atsargiai išimkite seną saugiklį ir pakeiskite jį nauju, tokio paties tipo ir nominalios vertės saugikliu.
5. Replace the batteries and battery compartment cover.

Svarbu: Never use a fuse with a different rating or bypass a fuse. This can damage the multimeter and pose a serious safety hazard.
