  • VΩHzTemp: Positieve input voor voltage, resistance, frequency, temperature, capacitance, diode, and continuity measurements.
  • COM: Gemeenschappelijke (negatieve) ingang voor alle metingen.
  • mA: Positive input for current measurements up to 200mA.
  • 10A: Positive input for current measurements up to 10A (MAX 30 sec. every 15 min.). This input is fused.
• hFE-socket: For testing transistor hFE (DC current gain).

5. Instellen

5.1 Batterij installatie

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

1. Zorg ervoor dat de multimeter UIT staat en koppel alle meetsnoeren los van de ingangen.
2. Zoek het klepje van het batterijcompartiment aan de achterkant van het apparaat.
3. Draai de bevestigingsschroef/schroeven los en verwijder voorzichtig de afdekking.
4. Sluit de 9V-batterij aan op de batterijclip en let daarbij op de juiste polariteit.
5. Plaats de batterij in het compartiment en sluit het deksel weer af, waarna u het vastdraait met de schroef/schroeven.

5.2 Aansluiting van de testkabel

Een correcte aansluiting van de meetsnoeren is cruciaal voor nauwkeurige en veilige metingen:

• Voor de meeste metingen (voltage, resistance, capacitance, frequency, temperature, diode, continuity), insert the rood testleiding in de VΩHzTemp jack en de zwart testleiding in de COM krik.
• For current measurements up to 200mA, insert the rood testleiding in de mA jack en de zwart testleiding in de COM krik.
• Voor stroommetingen tot 10A plaatst u de rood testleiding in de 10A jack en de zwart testleiding in de COM krik.

6. Gebruiksaanwijzing

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. Sluit de meetsnoeren aan op het circuit of het te testen onderdeel.
4. Lees de meetwaarde af op het lcd-scherm.
5. After measurement, disconnect the test leads and turn the multimeter OFF.

6.1 Specifieke meetfuncties

• 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-bron parallel.
• 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.
• Gelijkstroom (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.
• Wisselstroom (A~): Select the A~ range (mA or 10A jack). Follow the same series connection procedure as for DC current.
• Weerstand (Ω): Select the Ω range. Ensure the circuit is de-energized. Connect the test leads across the component to measure its resistance.
• Continuïteitstest (♫): Select the continuity function. If resistance is below approximately 50Ω, the buzzer will sound, indicating continuity.
• Diodetest (→|→): 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. Draai de draden om; op het display moet 'OL' (open loop) verschijnen als de diode goed is.
• Capaciteit (F): Select the F range. Ensure the capacitor is discharged before connecting the test leads.
• Frequentie (Hz): Select the Hz range. Connect the test leads across the signal source.
• Temperatuur (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. Onderhoud

7.1 Batterij vervangen

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 Reinigen

Om de multimeter schoon te maken, veegt u de behuizing schoon met een doekje.amp 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 Zekering vervangen

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. Probleemoplossing

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

• Geen scherm: Check if the multimeter is turned ON. Verify the 9V battery is correctly installed and has sufficient charge. Replace the battery if necessary.
• Onjuiste metingen: 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' (Overbelasting) indicatie: 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.
• Geen continuïteitszoemer: Check if the continuity function is selected. Ensure the circuit is de-energized.
• Huidige meting werkt niet: 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.
