FAQ

Q: What’s the storage capacity, storage format and data storage interval of SD card?

A: The meter is equiped with standard 4G SD card while saving the data of electrical parameter, energy, event, SOE, alarm. Also, the setting of storage interval could be changed. (1 min interval for electrical parameter and 1 hour interval for energy)

Q: How should I select the expanded modules of APM5xx?

A: Our users can select 3 of the optional modules at will even repeatly except for communication module. Also, the order of module installation could be random

Q: The features of APM5xx?

A: Except for wave record and flicker record function, 0.2S measuring accuracy can also be a option. Also, users can measure the data through browser by using Ethernet auto WEB.

Q: As for the auxiliary power supply of APM5xx?

A: AC/DC 85~265V or 115~415V is both optional. Also, 380V line voltage can also serve as power supply.
