DCA55:

Connect any way round to automatically identify and measure a wide range of semiconductor devices. The DCA55 will automatically identify the type of the part, pinout and many component parameters. Components supported include bipolar NPN/PNP transistors, darlingtons, diode-protected transistors, transistors with built-in resistors, enhancement mode MOSFETs, depletion mode MOSFETs, diodes, diode networks, LEDs, 2 and 3 lead bicolour LEDs, JFETs and many more. Further measurements are displayed including transistor gain, leakage current, pn voltage drops, LED voltages, MOSFET threshold voltages and much more. Even if you don't know anything about the part, just connect it in any configuration and the DCA55 will identify the type of part for you and also identify all the leads. Supplied with universal gold plated hook probes, battery and illustrated user guide. Not designed for in-circuit testing.

Key Features:

• Automatic pinout detection and identification, connect any way round.
• Automatic part type identification.
• Supports semiconductors including transistors, MOSFETs, diodes, LEDs, JFETs and much more.
• Detection of special component features such as transistors with diodes or transistors with built-in resistors.

Handheld LCR analyser providing measurements for inductance, capacitance and resistance. The component type is automatically detected for you, just connect and press "test". The test frequency is automatically selected to provide the best measurement resolution. Test frequencies include DC, 1kHz, 15kHz and 200kHz. Inductance from 1uH to 10uH, minimum resolution of 1uH, typical accuracy of ±1.5% between 100uH and 100mH. Capacitance from 1pF to 10,000uF, minimum resolution of 1pF typical accuracy of ±1.5% between 200pF and 500nF. Resistance from 1R to 2MR, typical accuracy of ±1%. Test frequency is displayed with the measurement. Inductor DC resistance also displayed when testing inductors. Supplied with removable gold plated hook probes, battery and user guide. Compatible with standard 2mm test connectors. Not designed for in-circuit use.
