GW-Instek PCS-1000I Precision Current and Voltage Meter

The PCS-1000I from GW-Instek is a high-quality precision instrument for current and voltage measurements with an isolated output. The instrument is equipped with five independent shunt resistors for different current measurement ranges: 300A, 30A, 3A, 300mA, and 30mA. This makes it suitable for various applications with different current levels. Internally, the PCS-1000I uses two sets of 24-bit ADCs and electronic components with a low temperature coefficient, aimed at accurate current measurements of power supplies. The instrument is highly accurate and can be used for adjusting and calibrating measuring instruments. Temperature fluctuations do not cause measurement errors. The PCS-1000I automatically selects the optimal measurement range with the highest resolution, eliminating the need for manual selection and increasing ease of operation.

Output and Oscilloscope Connectivity

The device provides a BNC output that can be connected directly to an oscilloscope to observe current waveforms without a current probe. Because general-purpose oscilloscopes typically do not have isolated channels and their input and output are connected at a common point, measurement errors can occur due to the load on the output. The isolated current output of the PCS-1000I prevents these measurement errors with non-isolated oscilloscopes.

Communication and Control

The PCS-1000I is a high-precision AC/DC current shunt meter that offers USB and GPIB communication interfaces for remote control. It supports simultaneous voltage and current measurements. SCPI commands allow users to control the instrument via a PC and read out measurement data.

Applications

Thanks to its high precision, automatic range selection, and isolated output, the PCS-1000I is ideal for adjusting, calibrating, and accurately measuring current in various industrial and laboratory environments. GW Instek’s PCS-1000I combines precision, ease of use, and reliability in a single instrument, making it a valuable addition to professional measurement setups.
