1. Introduktion
The diymore LCR-TC1 is a versatile multi-function tester designed for identifying and measuring various electronic components. It can automatically detect NPN and PNP bipolar transistors, N-channel and P-channel MOSFETs, JFETs, diodes (including dual diodes), thyristors, triacs, resistors, capacitors, and inductors. This device provides automatic pinout detection and displays component parameters on a color LCD screen, making it an essential tool for electronics enthusiasts and professionals.
2. Sikkerhedsoplysninger
- Always ensure components are fully discharged before testing, especially capacitors. High voltage capacitors can cause damage to the tester or personal injury.
- Do not attempt to test components while they are connected to a live circuit.
- Use the device in a dry environment. Avoid exposure to moisture or extreme temperatures.
- Åbn ikke enheden casing. Der er ingen dele indeni, som kan serviceres af brugeren.
- Hold enheden væk fra stærke elektromagnetiske felter.

5. Opsætning
5.1 Opladning af enheden
The LCR-TC1 is powered by a built-in rechargeable lithium-ion battery. Before first use, or if the battery is low, connect the provided Micro USB cable to the device's charging port and a standard USB power adapter (not included). The display will indicate charging status. A full charge typically takes a few hours.
5.2 Tænd
Press the 'Start' button to power on the device. It will perform a brief self-test and then be ready for component testing.
6. Betjeningsvejledning
6.1 Tilslutning af komponenter
Components can be connected in two ways:
- Using the ZIF Socket: For components with standard pin spacing (e.g., transistors, diodes), insert the pins into the corresponding holes in the ZIF socket (labeled 1, 2, 3). Ensure good contact and close the ZIF socket lever.
- Using Test Clips: For larger components or those without standard pins, use the provided test clips. Connect the clips to the three test points on the device (also labeled 1, 2, 3) and then to the component leads.

6.2 Initiating a Test
Once the component is securely connected, press the 'Start' button. The tester will automatically identify the component type, determine its pinout, and display relevant parameters on the color LCD screen.
6.3 Fortolkning af resultater
The display will show different information depending on the component tested:
- Modstande: Resistance value in Ohms (Ω), Kilohms (kΩ), or Megohms (MΩ).
- Kondensatorer: Capacitance value in Farads (F), microFarads (µF), nanoFarads (nF), or picoFarads (pF). It may also display Equivalent Series Resistance (ESR) and Voltage Loss (Vloss).
- Induktorer: Inductance value in Henrys (H), milliHenrys (mH), or microHenrys (µH). It may also show the DC resistance.
- dioder: Fremad voltage drop (Vf) and junction capacitance. For Zener diodes, it may indicate the Zener voltage if within range.
- Transistors (BJT, MOSFET, JFET): Identifies NPN/PNP (BJT) or N-channel/P-channel (MOSFET/JFET), displays pinout (Base, Collector, Emitter or Gate, Drain, Source), current gain (hFE for BJT), threshold voltage (Vf for MOSFET), and gate capacitance.
- Thyristors/Triacs: Identifies the component type.
6.4 Selvkalibrering
For optimal accuracy, it is recommended to perform a self-calibration periodically or if you suspect inaccurate readings. To calibrate, short all three test points (1, 2, 3) together, then press and hold the 'Start' button. Follow the on-screen prompts. The device will guide you through the calibration process, which typically involves removing the short circuit when instructed.
7. Vedligeholdelse
7.1 Rengøring
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no dust or debris accumulates in the ZIF socket or test points.
7.2 Pleje af batterier
To prolong battery life, avoid fully discharging the battery frequently. If the device will not be used for an extended period, charge it to approximately 50% and store it in a cool, dry place. Recharge every few months to prevent deep discharge.
8. Fejlfinding
- "No component found" or "Unknown component": Ensure the component is correctly inserted into the ZIF socket or securely connected with test clips. Verify good electrical contact. The component might be faulty or outside the tester's measurement range.
- Unøjagtige aflæsninger: Perform a self-calibration as described in Section 6.4. Ensure the component is clean and free of oxidation.
- Enheden tændes ikke: Check battery charge level. Connect to a USB charger and try again.
- Problemer med skærm: Hvis displayet er svagt eller flimrer, kan batteriet være lavt. Genoplad enheden.
