2. Izmantojiet skrūvgriezi, lai atskrūvētu skrūvi, kas nostiprina vāku.
3. Ievietojiet divas AAA baterijas, ievērojot pareizo polaritāti (+ un -), kā norādīts nodalījuma iekšpusē.
4. Uzlieciet atpakaļ akumulatora nodalījuma vāku un nostipriniet to ar skrūvi.

4.2. Testa vadu pievienošana

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

• Ievietojiet melno testa vadu "COM" (kopējā) ligzdā.
• Lielākajai daļai tilpumatage, 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. Lietošanas instrukcijas

The Sealey MM20HV offers 8 functions for various electrical measurements.

5.1. Ieslēgšana/izslēgšana

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. Measuring DC 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 DC Voltage diapazonā (piemēram, 200 mV, 2 V, 20 V, 200 V, 600 V). Ja spriegumstage is unknown, start with the highest range and decrease as necessary.
3. Pievienojiet testa zondes mērāmajai sastāvdaļai vai ķēdei.
4. Izlasiet sējtage vērtība LCD displejā.

5.3. Maiņstrāvas mērīšana 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 diapazons (piemēram, 200 V, 600 V).
3. Pievienojiet testa zondes maiņstrāvas spriegumamtage avots.
4. Izlasiet sējtage vērtība LCD displejā.

5.4. Measuring DC Current (A=)

Uzmanību: Nekad nepievienojiet multimetru paralēli sprieguma mērītājam.tagMērot strāvu, izmantojiet e avotu. Vienmēr pievienojiet to virknē ar slodzi.

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. Atveriet ķēdi, kurā tiks mērīta strāva, un pievienojiet multimetru virknē.
5. Izlasiet pašreizējo vērtību LCD displejā.

5.5. Measuring Resistance (Ω)

Brīdinājums: Pirms pretestības mērīšanas pārliecinieties, vai ķēde ir atvienota no strāvas un visi kondensatori ir izlādēti.

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. Nolasiet pretestības vērtību LCD displejā.

5.6. Skaņas nepārtrauktības pārbaude

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. Pievienojiet testa zondes ķēdei vai komponentam.
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 drop. Reverse the probes; the display should show "OL" (Open Loop) for a good diode.
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. Datu saglabāšanas 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. Apkope

6.1. Tīrīšana

Noslaukiet korpusu ar reklāmuamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is off and disconnected from any circuits before cleaning.

6.2. Akumulatora nomaiņa

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

6.3. Drošinātāju nomaiņa

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

1. Ensure the multimeter is turned off and all test leads are disconnected.
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. Carefully remove the old fuse and replace it with a new fuse of the exact same type and rating.
5. Replace the batteries and battery compartment cover.

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