5. Configurare

5.1 Instalarea bateriei

The C-LOGIC 5100 requires one 9V 6F22 battery (not included). To install or replace the battery:

1. Ensure the multimeter is turned OFF and disconnect all test leads from the input jacks.
2. Localizați capacul compartimentului bateriilor din spatele unității.
3. Deșurubați șurubul (șuruburile) de fixare și scoateți cu grijă capacul.
4. Conectați bateria de 9V la clema bateriei, respectând polaritatea corectă.
5. Introduceți bateria în compartiment și puneți la loc capacul, fixându-l cu șurubul (șuruburile).

5.2 Conectarea cablurilor de testare

Conectarea corectă a sondelor de testare este crucială pentru măsurători precise și sigure:

• Pentru majoritatea măsurătorilor (vol.tage, resistance, capacitance, frequency, temperature, diode, continuity), insert the roşu cablul de testare în VΩHzTemp jack și negru cablul de testare în COM jack.
• For current measurements up to 200mA, insert the roşu cablul de testare în mA jack și negru cablul de testare în COM jack.
• For current measurements up to 10A, insert the roşu cablul de testare în 10A jack și negru cablul de testare în COM jack.

Urmați acești pași generali pentru efectuarea măsurătorilor:

1. Turn the multimeter ON using the ON/OFF switch.
2. Select the desired function and appropriate range using the rotary dial. If unsure of the range, start with the highest range and work downwards.
3. Conectați sondele de testare la circuitul sau componenta testată.
4. Citiți valoarea măsurată pe afișajul LCD.
5. After measurement, disconnect the test leads and turn the multimeter OFF.

6.1 Funcții specifice de măsurare

• DC Voltage (V=): Select the V= range. Connect the red lead to the positive side and the black lead to the negative side of the DC voltagsursa în paralel.
• AC Voltage (V~): Select the V~ range. Connect the test leads across the AC voltage source in parallel. Polarity is not critical for AC voltage.
• Curent continuu (A=): Select the A= range (mA or 10A jack). Disconnect power to the circuit. Open the circuit where current is to be measured and connect the multimeter in series. Reapply power.
• Curent alternativ (A~): Select the A~ range (mA or 10A jack). Follow the same series connection procedure as for DC current.
• Rezistență (Ω): Select the Ω range. Ensure the circuit is de-energized. Connect the test leads across the component to measure its resistance.
• Test de continuitate (♫): Select the continuity function. If resistance is below approximately 50Ω, the buzzer will sound, indicating continuity.
• Test diode (→|→): Select the diode function. Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage drop. Reverse the leads; the display should show 'OL' (open loop) for a good diode.
• Capacitate (F): Select the F range. Ensure the capacitor is discharged before connecting the test leads.
• Frecvența (Hz): Select the Hz range. Connect the test leads across the signal source.
• Temperatura (Temp): Select the Temp range. Connect a K-type thermocouple (if included or purchased separately) to the VΩHzTemp and COM jacks.
• Transistor hFE: Insert the transistor's emitter, base, and collector leads into the corresponding holes in the hFE socket, ensuring correct NPN/PNP type selection.
