Indian review of NanoRanger by Pallav Aggarwal

NanoRanger is a precision current measurement tool by Altonovus Ltd, U.K. It can measure current from 1nA to 800mA with a resolution of 10pA. It has very good accuracy and it can also be controlled by a USB interface.

Features: - A large 11-digit display shows mA, uA, nA, and pA, all on one line. - Running Average reading (current and time elapsed) to measure the power consumption of specific events; for example, a radio transmission. - Fully isolated USB Interface for device control and readings export. - The Range Bar can be ‘bracketed’ or limited to just one range. - Range Bar movement after every reading shows that NanoRanger® is operating. - Range Coverage Bar shows the ranges covered during the measurement. - Low Burden Voltage ( less than 50mV) on all ranges. - Fast Up-Range switching (30uS / range) under load changes. - Down-range switching when full reading is below range threshold. - Readings every 300mS, built up from 180 samples and averaged to tune out mains noise (both 50 Hz and 60 Hz). - A new 'Fast Sample' Mode, running at 150 measurements per second. Update the firmware with the latest if you have older firmware on your meter. - SNR display indicates the noise level on the signal. - User-configurable Auto Power-off timer. - The NanoRanger® dimensions are 148 x 90 x 30mm. - 2 x AA batteries give around 150 hours of operation. In this review video 📽️ he sharesthe following details:
