As many readers will know, there are some very neat component testers available at very low cost these days.
The cheaper models tend to be an open PCB architecture so do appear a little DIY. The software within appears to be pretty clever however. It is no surprise that many such component testers are coming out of China in different formats, but running the same software.
The subject of this thread was a new model that caught my eye. It is the B-Side ERS02 PRO and it costs around $20. I already own a few component testers and ESR meters etc, but this particular unit looked interesting. It arrived this week so I thought i would share details of it and its internal design. The unit is built inside a pretty decent little casing that tilts the LCD display to a bench use friendly angle. The front panel contains two power and test buttons for left and right handed use which I thought quite clever. It also contains a neat little SMD test plate as well as leaded component spring clips and standard 4mm test lead sockets. A pretty decent line-up really
An interesting addition to the normal line up of test sockets etc is the capacitor discharge socket to make capacitors safe to test. The designer of this units case has obviously put some thought into what a user would find useful in daily use.
The LCD display is nice and large and equipped with a decent backlight. Upon switching the unit on the battery voltage is displayed and the unit enters its test mode. A calibration requirement is shown and instructions on how to proceed. The menus options are impressive as will be seen in the pictures that follow. This is a very versatile little box of tricks.
I was pleased to see that the manufacturer has seen fit to include a link to the original source of the design.
I will fill in the component list her later but for now here are the pictures......
