5. Configuració

5.1 Instal·lació de la bateria

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

1. Assegureu-vos que el multímetre estigui apagat i desconnecteu tots els cables de prova dels endolls d'entrada.
2. Localitzeu la tapa del compartiment de la bateria a la part posterior de la unitat.
3. Descargoleu el(s) cargol(s) de subjecció i retireu la coberta amb cura.
4. Connecteu la pila de 9 V a la pinça, respectant la polaritat correcta.
5. Col·loqueu la bateria al compartiment i torneu a col·locar la tapa, fixant-la amb el(s) cargol(s).

5.2 Connexió del cable de prova

Proper connection of test leads is crucial for accurate and safe measurements:

• Per a la majoria de mesures (voltage, resistance, capacitance, frequency, temperature, diode, continuity), insert the vermell cable de prova a la VΩHzTemp jack i el negre cable de prova a la COM jack.
• For current measurements up to 200mA, insert the vermell cable de prova a la mA jack i el negre cable de prova a la COM jack.
• For current measurements up to 10A, insert the vermell cable de prova a la 10A jack i el negre cable de prova a la COM jack.

6. Instruccions de funcionament

Follow these general steps for making measurements:

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. Connecteu els cables de prova al circuit o component que s'està provant.
4. Llegiu el valor de mesura a la pantalla LCD.
5. After measurement, disconnect the test leads and turn the multimeter OFF.

6.1 Funcions de mesura específiques

• 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 voltage font en paral·lel.
• Vol. ACtage (V~): Select the V~ range. Connect the test leads across the AC voltage source in parallel. Polarity is not critical for AC voltage.
• DC Current (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.
• AC Current (A~): Select the A~ range (mA or 10A jack). Follow the same series connection procedure as for DC current.
• Resistència (Ω): Select the Ω range. Ensure the circuit is de-energized. Connect the test leads across the component to measure its resistance.
• Prova de continuïtat (♫): Select the continuity function. If resistance is below approximately 50Ω, the buzzer will sound, indicating continuity.
• Prova de díodes (→|→): 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.
• Capacitat (F): Select the F range. Ensure the capacitor is discharged before connecting the test leads.
• Freqüència (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.

7. Manteniment

7.1 Substitució de la bateria

When the low battery indicator appears on the display, replace the 9V battery as described in Section 5.1. Using a multimeter with a low battery can lead to inaccurate readings.

7.2 Neteja

Per netejar el multímetre, netegeu la carcassa amb aiguaamp cloth and a mild detergent. Do not use abrasive cleaners, solvents, or alcohol, as these may damage the casing or display. Ensure the multimeter is completely dry before use.

7.3 Canvi de fusibles

If the 10A current measurement function stops working, the fuse may need replacement. This procedure should only be performed by qualified personnel. Refer to the specifications for the correct fuse type and rating. Always disconnect test leads and power off the unit before opening the case.

8. Solució De Problemes

If your C-LOGIC 5100 Multimeter is not functioning as expected, refer to the following common issues and solutions:

• Sense pantalla: Check if the multimeter is turned ON. Verify the 9V battery is correctly installed and has sufficient charge. Replace the battery if necessary.
• Lectures incorrectes: Ensure the correct function and range are selected for the measurement. Check that the test leads are securely connected to the correct input jacks and to the circuit. Verify the battery is not low.
• 'OL' (Overload) Indication: This indicates that the input value exceeds the selected range. Switch to a higher range or ensure the input is within the multimeter's maximum specifications.
• Sense brunzidor de continuïtat: Check if the continuity function is selected. Ensure the circuit is de-energized.
• La mesura actual no funciona: Check the fuse for the current input (especially the 10A input). Replace if blown. Ensure test leads are connected to the correct current jacks (mA or 10A) and the multimeter is in series with the circuit.
