The Instek PCS-1000 High-Precision AC/DC Current Shunt Meter carries built-in current shunts and high-accuracy current measurement circuits. The PCS-1000 not only measures current in five current levels (300A, 30A, 3A, 300mA and 30mA), it also measures voltage at 6 1/2-digit resolution, simultaneously. This unique feature puts the PCS-1000 in an unprecedented position - after long operations, it is able to maintain a high measurement accuracy, despite temperature variations. This is due to the instrument's core design, which is based on high stability and low temperature coefficient shunts. PCS1000, a verification-lab-level current and voltage measurement instrument, is suitable for research and development, quality verification and testing jobs of all power products, such as power supply, communications system power, server power and electronic load.
