Function Advantage:
DC high current measurement: the built-in broadband current comparator completes the I/V conversion and converts the current signal into a voltage signal, which is suitable for direct access DC energy meter verification device
Small signal voltage measurement: can directly measure the voltage signal, suitable for indirect access (shunt access) DC energy meter verification device.
Stability test: stability test time can be set, and visual display of stability value. Optional power, voltage, current stability test.
Statistical analysis of l data: calculate the maximum, minimum, average, standard deviation and so on.
DC ripple test: maximum 5 kHz of measurement bandwidth, uncertainty 0.1%
Power metering: with standard power pulse input / output interface, it can be used as the standard of high grade DC power metering.
Smart control: can access other computer systems to achieve automatic measurement.
HMI (Human-Machine Interaction): easy to operate, equipped with 7-inch capacitive screen, beautiful and generous display interface, rich and intuitive content.
