Salut à tous!
Je me demande quels testeurs de composants acheter? J'aimerais avoir le plus complet et le plus précis. Je préfère payer un peu plus que d'avoir à acheter plusieurs appareils bon marché. Dois-je acheter le moins cher pour acheter des nouveaux plus performants régulièrement ou un bon qui me durera longtemps vu que les mises à niveaux fréquentes n'apportent pas de très grandes fonctionnalités assez notables?
Par exemple, j'ai un oeil sur le LCR TC1. le T7 et le T-7H.
J'ai essayé de comparer les spécifications, mais je suis trop débutant pour sortir de ma confusion.
La LCR 7H est le plus chère des trois, mais je ne sais pas si cela signifie que c'est la version la plus récente de cet appareil et si c'est le meilleur choix.
Par exemple:
Le TC1 fait ceci: Diode Zener: Zone de détection de transistor: 0.01-4.5V; Zone de détection de la diode Zener: 0,01-30 V
Mais le T-7H qui est plus cher, fait ceci: Détection automatique de la diode Zener (0.01-20V
---------------------------------------------------------------------------
Voici les caractéristiques (en anglais) du LCR TC1, du T7 et du T-7H
Feature: (LCR-TC1 Tester)
It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery etc.
It also can detect zener diode and has the function of self-calibration.
After detection, align the infrared remote control with the "IR" light, then press the button in the remote control, if the detector successfully decode it, it will display the data code and infrared wave form.
One button operation, automatically detect and shutdown, and you can press the multi-functional button to close the detector too.
Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly.
Not like the usual black and white display, this detector will show results in color.
