The measuring part of the device repeats the ESRmicro 4.0 circuitry. In this model, a microcontroller from Microchip PIC16F690 is used, a display from a NOKIA 1112 mobile phone is used as an indicator. The scale of the device is divided into three ranges with automatic selection of the measurement limit. Measurement currents for the ranges 0.3mA, 3mA, 30mA.
