Q. What is the latest version of the Atlas DCA?
Transistor tester dca55 upgrade#
If there is a short circuit within your component then the DCA will display ”Short circuit on RED GREEN” for example.Ī. The only way to upgrade the firmware is to send your unit to us. Sometimes it may still be able to see a pn (diode) junction within the component you’re testing, in which case it would display ”Diode or diode junction(s)”. Q. What will the DCA show if my component is faulty?Ī. Generally, the DCA would show ”Faulty or unknown component”. Both of these parameters are measured by the DCA. The main parameters that you may be interested in are hFE and Vbe.
Q. Can I use the DCA to match transistors?Ī. Yes. Low power sensitive Triacs and Thyristors (5V) will be shown as a regular diode and the forward voltage will be the voltage of the pn junction not the zener voltage).LEDs and bi-colour LEDs (2 lead and 3 lead types).Diodes and diode networks (2 and 3 lead types).Enhancement mode MOSFETs (N-Ch and P-Ch).Bipolar transistors (NPN/PNP inc Silicon/Germanium).Test voltage (into open circuit): ±5V (typical) Test current (into short circuit): ±5mA (typical) DCA55 Semiconductor Component Analyser instrument.Now features transistor leakage measurement and Germanium/Silicon identification. Automatically identifies type of component, pinout and other important parameters. Supports transistors MOSFETs, JFETs (gate pin only can be identified), diodes, LEDs and lots more. Parameter measurement (hFE, Vbe, Vf, leakage current etc).Pinout information (such as Base, Emitter, Collector etc).Component type (such as NPN transistor, P-Ch MOSFET, LED, diode etc).Connect any way round! The DCA55 then displays the following:
Intelligent and flexible semiconductor analyser. * Spänningsfall för dioder och transistorer * Gate-threshold-mätning för FET-transistorer * Detektering av typ för transistorer (kisel / germanium) * Förstärkning- och läckströmssmätning för transistorer Instrumentet är enkelt att använda och kan automatiskt identifiera komponenter och pinout. DCA55 är en smart mätinstrument för många typer av halvledare.
