4. Configurare

4.1. Instalarea bateriei

1. Asigurați-vă că multimetrul este oprit.
2. Localizați compartimentul bateriei în spatele dispozitivului.
3. Deșurubați capacul compartimentului bateriei.
4. Insert four (4) 1.5V AAA batteries, observing correct polarity.
5. Puneți la loc capacul și fixați-l cu șurubul.

4.2. Conectarea cablurilor de testare

• Pentru majoritatea volumuluitage, resistance, capacitance, frequency, and temperature measurements, connect the red test lead to the V/Ω/Hz/CAP/°C input jack and the black test lead to the COM input jack.
• For current measurements up to 600mA, connect the red test lead to the µA/mA input jack and the black test lead to the COM input jack.
• For current measurements up to 10A, connect the red test lead to the 10A input jack and the black test lead to the COM input jack.

5. Instrucțiuni de utilizare

Turn the rotary switch to the desired measurement function. Use the MODE button to cycle through sub-functions (e.g., AC/DC voltage, diode/continuity). The RANGE button allows manual range selection, while the REL button activates relative measurement. The HOLD button freezes the display reading, and the PEAK button captures peak values. The MAX/MIN/AVG button cycles through maximum, minimum, and average readings.

5.1. Zbortage Measurement (DCV, ACV, ACV+DCV)

1. Set the rotary switch to V (DCV) or V~ (ACV).
2. Connect test leads as described in Section 4.2 (V/Ω/Hz/CAP/°C and COM).
3. Conectați sondele de testare în paralel cu circuitul sau componenta care urmează să fie măsurată.
4. For ACV+DCV or Lo Z (low impedance) measurements, use the MODE button to select the appropriate function.

5.2. Current Measurement (DCA, ACA)

1. Set the rotary switch to µA, mA, or 10A.
2. Connect test leads to the appropriate current input jack (µA/mA or 10A) and COM.
3. AVERTIZARE: Connect the meter in series with the circuit. Never connect the meter in parallel to a voltagsursa de curent atunci când este în modul de curent, deoarece acest lucru poate arde siguranța sau poate deteriora contorul.

5.3. Măsurarea rezistenței (Ω)

1. Setați comutatorul rotativ pe Ω.
2. Connect test leads to V/Ω/Hz/CAP/°C and COM.
3. Asigurați-vă că circuitul sau componenta este dezactivată înainte de a măsura rezistența.
4. Conectați sondele de testare la componentă.

5.4. Capacitance Measurement (CAP)

1. Set the rotary switch to CAP.
2. Connect test leads to V/Ω/Hz/CAP/°C and COM.
3. Ensure capacitors are fully discharged before measurement to prevent damage to the meter.
4. Conectați sondele de testare la condensator.

5.5. Măsurarea frecvenței (Hz)

1. Set the rotary switch to Hz.
2. Connect test leads to V/Ω/Hz/CAP/°C and COM.
3. Conectați sondele de testare la sursa de semnal.

5.6. Temperature Measurement (°C)

1. Set the rotary switch to °C.
2. Connect the K-type temperature sensor to the temperature adapter, then insert the adapter into the V/Ω/Hz/CAP/°C and COM jacks.
3. Place the tip of the temperature sensor on or near the object whose temperature is to be measured.

5.7. Continuity Test and Diode Test

1. Set the rotary switch to the continuity/diode symbol.
2. Connect test leads to V/Ω/Hz/CAP/°C and COM.
3. For continuity, touch the test leads across the circuit. A buzzer will sound for continuity.
4. For diode test, connect the red lead to the anode and the black lead to the cathode of the diode. The forward voltagVa fi afișată o picătură. Inversați firele pentru a verifica dacă există un circuit deschis.

6. Întreținere

6.1. Curatenie

Ștergeți contorul cu reclamăamp o lavetă și un detergent blând. Nu utilizați abrazive sau solvenți. Asigurați-vă că aparatul de măsură este uscat înainte de utilizare.

6.2. Înlocuirea bateriei

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Use only 1.5V AAA batteries.

6.3. Înlocuirea siguranței

If the current measurement function fails, the fuse may need replacement. Refer to the full instruction manual for detailed fuse replacement procedures. Always use fuses of the specified type and rating.

7. Depanare

• Fără afișaj sau citiri neregulate: Check battery charge and ensure proper battery installation.
• Nicio măsurare a curentului: Check the fuse. Ensure test leads are connected to the correct input jacks and in series with the circuit.
• Citiri incorecte: Verify the correct function and range are selected. Ensure test leads are properly connected and not damaged.
• "OL" or "OVER" displayed: The measured value exceeds the selected range. Select a higher range or ensure the input is within the meter's capabilities.
