Functional Features

◉ Device magnetic field measurement: The built-in micro Tesla meter is used to measure the three-dimensional AC/DC magnetic field at the position of the self moving measuring device's tested meter.
◉Temperature and humidity measurement: Equipped with miniature temperature and humidity sensors, used to measure the ambient temperature and humidity at the location of the electric energy meter calibration device on the water flow line.
◉ Wiring test: Using pressure detection technology inside the wiring hole to check whether the device's plug-in wires are in good condition and reduce the probability of false detection.
Clock error measurement: Equipped with a micro clock measurement module, it can accurately measure the second pulse emitted by the electric energy meter calibration device on the water flow line.
◉ Recognition unit test: able to set screen fields and display characters with missing strokes
◉ Testing date and time record: used to record the current testing time, date, and other information.
Powered by a built-in battery, it can work continuously for 8 hours, reducing the impact of traditional PT power supply methods on accuracy testing.
The external dimensions are consistent with the existing national energy meter and can be fully automated for testing.
