Uživatelská příručka k multifunkčnímu tranzistorovému testeru diymore LCR-TC1

1. Úvod

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. Bezpečnostní informace

• 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.
• Používejte zařízení v suchém prostředí. Nevystavujte jej vlhkosti nebo extrémním teplotám.
• Neotevírejte zařízení casing. Uvnitř nejsou žádné součásti, které by mohl uživatel opravit.
• Udržujte zařízení mimo dosah silných elektromagnetických polí.

3. Obsah balení

5. Nastavení

5.1 Nabíjení zařízení

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 Zapnutí

Press the 'Start' button to power on the device. It will perform a brief self-test and then be ready for component testing.

6. Návod k obsluze

6.1 Připojení komponent

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 Interpretace výsledků

The display will show different information depending on the component tested:

• Rezistory: Resistance value in Ohms (Ω), Kilohms (kΩ), or Megohms (MΩ).
• Kondenzátory: Capacitance value in Farads (F), microFarads (µF), nanoFarads (nF), or picoFarads (pF). It may also display Equivalent Series Resistance (ESR) and Voltage Loss (Vloss).
• Induktory: Inductance value in Henrys (H), milliHenrys (mH), or microHenrys (µH). It may also show the DC resistance.
• diody: Vpřed svtage 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 Samokalibrace

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. Údržba

7.1 Čištění

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 Péče o baterii

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. Řešení problémů

• "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.
• Nepřesné údaje: Perform a self-calibration as described in Section 6.4. Ensure the component is clean and free of oxidation.
• Zařízení se nezapne: Check battery charge level. Connect to a USB charger and try again.
• Problémy se zobrazením: If the display is dim or flickering, the battery might be low. Recharge the device.
