GW Instek's GPM-8320/8330 digital power meters are designed for precision three-phase AC power source measurement and are the perfect tool for most electrical and electronic product testing applications. These models offer a broad testing bandwidth of DC to 0.1Hz-100 kHz, in addition to  16-bit A/D converters and a 300 kHz sampling rate. Moreover, they have a 5-inch TFT LCD display, show 5-digit measurement readings, offer 25 power measurement parameters, and can make precise measurements.

The GPM-8320/8330 models also offer the ability to display waveforms (voltage/current/power), perform integration measurements, analyze harmonics at various orders (compliant with IEC61000-4-7 for 50/60Hz measurements), support external sensor inputs, and provide multiple communication interfaces. These features contribute to providing users with precise, convenient, and comprehensive power measurement capabilities, making them the most comprehensive and economical choice among power meters in their category. 

The GPM-8320/8330 models offer various input voltage configuration wiring modes, such as 1P3W, 3P3W, 3P4W, and 3V3A. Users have the flexibility to choose the most suitable wiring mode based on their specific measurement needs. These models are designed to accommodate a rated input voltage of 1000V and an input current of 20A. They support a minimum current range of 0.5A, which ensures precision with a remarkable resolution of 0.1mA. The power measurement resolution is equally impressive, with a granularity of 0.1mW.

In terms of accuracy and performance, the GPM-8320/8330 units stand out. They maintain a crest factor of 3, and this can extend to 6 or 6A for half ranges. This feature contributes to accurate measurements across various scenarios. The voltage, current, and power measurements boast an impressive accuracy level of ±0.1% reading plus ±0.05% range.

The devices also offer flexibility in measurement modes, including AC+DC, AC, DC, and V-MEAN. Depending on the chosen mode, users gain access to a comprehensive set of up to 25 related parameters, enhancing the depth and breadth of power measurement capabilities.
