Single Phase Energy Meter Portable Tester

SP-3301A Portable Single-phase Watt-hour Meter Testing Device
Main features
l 0.1%portable single-phase electric source integrative function
Voltage is 220V, with largest current 10A. It is possible to input different current and angles. To chose different checking points by using 0keying to check single-phase device. This device also can set checking point unit that makes this device calibrate itself automatically and save and print checking results.
l Single-phase field use checking function
When it is used as a field testing device, it is a high-accuracy field use checking device (±0.1%).But there are essential differences between this device and single-phase field use checking device with electric meter chip. Through 16 bit A/D and high-speed 32 bit DSP processor, it samples signals of voltage and current and calculates electric parameter. Meanwhile, its current output function can be used as analog virtual load, largely convenient for filed measure of single-phase watt-hour meter.
l Transformer's self-calibration function
This device utilizes our company's patent technology, automatically measuring transformer's error and calibrating it, with the purpose to guarantee the constant stability of transformer's error.
l Waveform showing function: directly display U, I waveform;
l Harmonic testing function: show all data of 2nd ~25th harmonic waveform in forms of histogram;
l Save and query function: able to save 1000pieces of checking records. Able to inquire in different ways, including fuzzy query;
l Distant upgrade function: through download updating package, able to upgrade the software system of HA and enjoy new function and characteristics of HA constantly;
l Bilingual-language function: able to read both Chinese and English in the screen;
l Help function: when press F1, help interface will pop out;
l Multi-ways of electricity supply: three ways to supply electric energy, using battery, electricity input online or external.
