 Saelig Co., Inc. has introduced the NanoRanger® NR-01 – an affordable, highly accurate 3.5-digit DC ammeter designed for accurately measuring very low currents. With automatic dynamic ranging (9 ranges across 8.5 decades), NanoRanger® measures currents from 1nA up to 800mA with a maximum resolution of 10pA. Each instrument is supplied factory calibrated, eliminating the requirement for high-cost precision components in the design, and thus keeping the purchase price low. The current is measured with a 12-bit ADC which is oversampled and automatically averaged to produce a 16-bit result. Samples are taken every 170uS. Readings are shown every 300mS, built up ...
