High Accuracy Electrical Calibration Equipment For For DC Energy Meter Verification


XL-9200 DC electric energy meter verification device is the latest standard voltage and current source designed and developed by Shenzhen Xinglong Technology Co., Ltd., which is based on the current national standard for DC energy meter verification and adopts the latest technology. The main components are imported industrial grade devices, which can support 0~200ADC high current signal, the accuracy level is better than 0.05%; 0~1000V DC voltage output, accuracy grade is better than 0.02%; 0~5V DC voltage analog shunt Output, accuracy class 0.05%, and support voltage, current output ripple superposition function, can be used for DC load meter virtual load verification, ripple interference test, or as a separate voltage standard source, current standard source, power standard source The device has passed the test of Shenzhen Metrology Institute.
The device adopts 800×600 liquid crystal display, the interface is clear and simple, the operation is convenient, and the visual effect is good. The core module uses 32-bit high-speed DSP combined with adaptive Lagrangian interpolation algorithm to eliminate the hardware non-synchronization error of DC ripple. Waveform quantization uses 32-bit dual modulation output technology to ensure high output accuracy. The output has overcurrent and overheat protection, which is safe and reliable.

3. Notes (Important)


l Although the device has three inspected pulse input ports, only one of the inspected tables that are not isolated for voltage and current input can be calibrated at a time.
l The voltage and current outputs of the device are isolated from each other, allowing the user to have a short contact between voltage and current during use, that is, only a single point connection of voltage and current is allowed.
l The voltage output can be as high as 1000V, which is a threat to personal safety. Please pay attention to safety.
