LCR-T4 Tester para transistores, condensadores, ESR, indutância e resistência

El Lcr-T4 normalment mesura 70x90x28 mm i pesa al voltant de 70 g. El cos principal és de plàstic ABS amb pantalla LCD integrada. A la caixa normalment s'hi inclou el mòdul Lcr-T4, suport per a transistors i connectors o cables, però el contingut pot variar segons el proveïdor; es recomana revisar la llista exacta abans de comprar.

El tester funciona amb una pila estàndard de 9 V (tipus 6F22/PP3). El seu consum és baix (només 20 nA en espera), però la mesura fiable requereix que la bateria lliuri almenys 7 V. No és compatible amb fonts d'alimentació externes ni amb voltatges superiors, per evitar danys al circuit.

Els problemes habituals inclouen resultats erràtics per males connexions als pins, bateria baixa o components fora de rang. Per solucionar-ho, assegureu la neteja i fermesa en el contacte dels terminals, substituïu la bateria si la pantalla mostra inestabilitats i verifiqueu que el component a mesurar estigui dins del rang de l'aparell.

A diferència d'un multímetre digital, el Lcr-T4 identifica automàticament el component i la disposició dels pins, a més de mesurar paràmetres avançats com ESR, Vth de MOSFET i hFE de BJTs, sense necessitat de configurar rangs manualment. Tanmateix, no mesura voltatge/corrent en circuit i la seva exactitud és inferior a la d'un multímetre professional avançat.

The Lcr-T4 typically measures 70 x 90 x 28 mm and weighs around 70 g. The main body is made of ABS plastic with an integrated LCD screen. The box usually includes the Lcr-T4 module, transistor socket, and connectors or cables, but the contents may vary by supplier; it is recommended to check the exact listing before buying.

The tester works with a standard 9 V battery (6F22/PP3 type). Its consumption is low (only 20 nA in standby), but reliable measurement requires the battery to provide at least 7 V. It is not compatible with external power supplies or higher voltages, to avoid damage to the circuit.

Common issues include erratic results due to poor contact on the pins, a low battery, or components outside the range. To solve this, ensure the terminals are clean and making firm contact, replace the battery if the display becomes unstable, and check that the component being measured is within the device's range.

Unlike a digital multimeter, the Lcr-T4 automatically identifies the component and its pin arrangement, and also measures advanced parameters such as ESR, MOSFET Vth and BJT hFE, without needing manual range selection. However, it does not measure voltage/current in circuit and its accuracy is lower than that of an advanced professional multimeter.
