On site verification instrument for electric energy meter

◆Main functions

Verify the error, accuracy, creep, and start-up of the electricity meter on site without disassembling the meter or disconnecting the power supply; Measure the voltage, current, active power, reactive power, power factor, etc. of the power supply grid. This product is an ideal instrument for measuring electricity and verifying energy meters. It is an essential tool for detecting electricity theft, measuring meters, and resolving electricity disputes. The on-site verification instrument for three-phase electric energy meters can also determine whether there are wiring errors.

◆Main Features

1. Verify the accuracy of the electric meter on site without dismantling it, suitable for verifying various types of energy meters such as mechanical, electronic, IC card, etc.
2. On site measurement of voltage, current, active power, reactive power, and power factor.
3. Adopting a large screen LCD display, it can simultaneously display various electrical parameters and meter errors at a glance.
4. There are two measurement methods available: automatic sampling and manual sampling using a photoelectric sensor.
