GW Instek's PCS-1000 is a dc and ac current shunt meter not only measures current in 300 A, 30 A, 3 A, 300 mA and 30 mA levels, but also simultaneously measures and displays voltage with 6-1/2 digit resolution. The PCS-1000 uses five high-precision shunt resistors (0.001, 0.01, 0.1, 1.0, and 10.0 ohm) as the basis for current and voltage measurements with a current measurement range from 30 mA to 300 A. The unit features a USB interface for control and data download and a GPIB interface for SCPI commands.
