![]() While this may be on the assumption that there is no need for any other type of attachment, it does make replacing damaged probes more difficult. One of the few downsides we found to this unit is that, unlike many other Peak Atlas products, these leads are fixed to the case with no plugs. Pin-outs are given by lead colour, so you always know which lead is which no matter which way you connect the probes. The information is displayed in a scrollable LCD, with a one-button scroll function to go through the different pages. The instrument then figures out what type of device it is connected to, what pin is which, and what the parameters are. One of the advantages of both types is that the three coloured spring-hook probes can be connected in any order to the terminals of the semiconductor in question. See Peak's website for the comparison chart. Peak Electronic Design have a comparison table published for the two devices, but we found reading this in conjunction with the ‘Technical Specifications’ appendix out of each product’s manual (also downloadable from Peak’s website) was informative. We bought the DCA75 Pro from Element 14, because it has more capability and a greater range of semiconductor types in its libraries. Peak makes two levels of Semiconductor Analyser, the DCA55 and the DCA75 Pro. Their products are innovative in terms of design, and sometimes in function, with no equivalent products around in some cases. Peak makes all their products in the UK, with parts sourced from within Europe. They’re still a lot more money than the $10 Chinese-made multimeters from retail electronics stores. ‘Affordable’ is a relative term of course, and we use it in comparison to other options. Peak Electronic Design is a United Kingdom-based electronic engineering firm who produce high-quality, affordable test equipment. Once it arrived, we had no regrets, so we wanted to share our experience with our readers. ![]() ![]() We liked the look of it so much, we bought one. However, while we were browsing, we discovered the Peak Atlas DCA Pro Semiconductor Analyser for three-terminal devices. Element 14 has a large array of test equipment, and we chose the Peak Atlas LCR40. In the Slayer Exciter project of issue 41, we briefly touched on the need for an LCR meter. One of the best and most valuable impulse buys we have ever made.
