Description
The GPM-8310 is a digital power meter for single-phase (1P/2W) AC measurement. It features 16-bit A/D, 300 kHz sampling, 5” TFT LCD, 25 measurement parameters, waveform display, harmonic measurement, integration function, and external sensor inputs for accurate and versatile measurements.
Rated voltage: 600V, current: 20A, minimum current 5 mA (0.1 µA resolution), power resolution 0.1 µW. CF can reach 3 (half-range 6 or 6A). Measurement modes: AC+DC, AC, DC, V-MEAN.
Advanced Features
Various Display Modes

Numeric mode: General (2 main + 8 secondary) or Simple (4 main). Waveform mode: oscilloscope display of voltage, current, and power with adjustable horizontal scale (25 µs/div – 1 s/div) and 3 zoom levels. Harmonics displayed as bars.
Rich Measurement Parameters

25 parameters: voltage, current, frequency, active/apparent/reactive power, power factor, crest factor, THD, max current ratio, MATH functions, etc. Integration function calculates average power/current over a defined period.
Superb Measurement Assistance

Supports high-voltage/high-current measurement with external PT/CT and EXT1/EXT2 inputs. Internal memory: 10,000 measurements, 4 panel settings for storage/recall.
Flexible Level-Changing Mechanism

Automatic or user-defined level-changing for integration function to save time and optimize testing.
Convenient Interfaces

Standard: RS-232C, USB Device/Host, LAN, GPIB. Optional Digital I/O (DA4) provides external control, DA4 output, and user-defined output.
