Overview
PEC-HAD single-phase energy meter on-site calibration device (three meter position)
Product Details
Can simultaneously verify 1-3 electronic single-phase energy meters.
● Can calibrate single-phase local cost control intelligent energy meters and single-phase remote cost control intelligent energy meters
The start and creep can automatically calculate the test time based on the table parameters, or the test time can be set by the user themselves.
The device is equipped with a wide limit standard energy meter, which facilitates the calibration of single-phase smart energy meters and the voltage, current, and power values of smart meters.
The device has fast protection and fault alarm functions, and can quickly cut off the power supply in case of voltage short circuit. The device does not operate in an open circuit current stateDamage; Can display and pronounce the fault type (current or voltage) and fault phase.
The device has a constant verification function.
The device has the function of writing characters.
The device has the function of receiving GPS standard clock to synchronize the electricity meter.
Each meter has an independent voltage circuit.
The current output is 60A and can work continuously for 0.5 hours (single meter 80A, triple meter 60A).
