4. Configurare

4.1. Instalarea bateriei

The ANENG DT830B requires a 9V 6F22 battery (not included). If "BAT" appears on the display, it indicates that the battery should be replaced.

1. Remove the screw from the back cover of the multimeter.
2. Scoateți cu grijă capacul din spate.
3. Connect the 9V battery to the battery clip, ensuring correct polarity (positive to positive, negative to negative).
4. Place the battery inside the compartment and reattach the back cover, securing it with the screw.

5. Instrucțiuni de utilizare

5.1. DC Voltage Măsurare

1. Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.
2. Set the RANGE switch to the desired DC VOLTAGE position. If the voltage to be measured is not known, set the switch to the highest range and reduce it until a satisfactory reading is obtained.
3. Conectați cablurile de testare la dispozitivul sau circuitul care se măsoară.
4. Voltage value and polarity will appear on the Digital Display.

5.2. AC Voltage Măsurare

1. Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.
2. Set the RANGE switch to the desired AC VOLTAGE position (e.g., 200V or 750V).
3. Conectați sondele de testare la sursa de curent alternativ.
4. Vol. ACtage value will appear on the Digital Display.

5.3. Măsurarea rezistenței

1. Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.
2. Set the RANGE switch to the desired OHM (Ω) position.
3. Dacă rezistența măsurată este conectată la un circuit, opriți alimentarea și descărcați toți condensatorii înainte de măsurare.
4. Conectați cablurile de testare la circuitul de măsurat.
5. The resistance value will appear on the Digital Display.

5.4. Măsurarea diodelor

1. Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.
2. Set the RANGE switch to the Diode symbol (Diode) position.
3. Conectați sonda roșie la anodul diodei și sonda neagră la catod.
4. Volumul înaintetage drop in mV will be displayed. If the diode is reversed, "1" will be shown.

5.5. Măsurarea tranzistorului (hFE)

1. Set the RANGE switch to the hFE position.
2. Determine whether the transistor is PNP or NPN type and locate the Emitter, Base, and Collector leads.
3. Insert the leads into the proper holes of the hFE Socket on the front panel.
4. The meter will display the approximate hFE value under the condition of base current 10µA and VCE 2.8V.

5.6. Măsurarea curentului continuu

WARNING: AC and DC current measurements require series connection to the circuit. Do NOT directly contact with measuring current like measuring voltage, as direct contact will burn out the instrument!

1. For measurements between 200µA and 200mA, connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack. For measurements up to 10A, connect the red test lead to the "10A" jack and the black test lead to the "COM" jack.
2. Set the RANGE switch to the desired DCA (DC Current) position.
3. Open the circuit to be measured and connect the test leads IN SERIES with the load.
4. The current value will appear on the Digital Display.
5. The 10A function is designed for intermittent use only. Maximum contact time of the test leads with the circuit is 15 seconds, with a minimum intermission time of 15 seconds between tests.

6. Specificații

Accuracies are guaranteed for 1 year, 23°C ± 5°C, less than 80%RH.

Notă: Parametrii de mai sus sunt doar pentru referință, iar măsurătorile reale ale echipamentului specific vor prevala.

7. Întreținere

7.1. Înlocuirea bateriei și siguranțelor

Fuses rarely need replacement and blow almost always as a result of operator error. If "BAT" appears in the display, it indicates that the battery should be replaced.

To replace the battery & Fuse (500mA/250V), remove the 2 screws in the bottom of the case, simply remove the old, and replace with a new one. Be careful to observe polarity.

CAUTION: Before attempting to open the case of the instrument, be sure to disconnect test leads from any energized circuits to avoid shock hazard.

8. Depanare

If the product is not operating properly, first check the battery and fuse as described in the Maintenance section. Ensure test leads are correctly connected for the desired measurement function and range. If issues persist, refer to the official support channels.

For questions about product use or if the product is not operating properly, contact ANENG customer service. They can provide assistance and solutions.

9. Sfaturi pentru utilizatori

• Always ensure the correct function and range are selected before making a measurement to prevent damage to the multimeter or the circuit.
• When measuring current, always connect the multimeter in series with the circuit. Connecting it in parallel will cause a short circuit and damage the device.
• The multimeter comes with test leads. Ensure they are properly connected to the correct jacks for your measurement.
