FAQs
Can this meter be used for single-phase applications?
Yes, the Finder 7M.38.8.400.0312 can be used in single-phase applications with a current rating up to 80A, although it is designed with 3-phase systems in mind.
What does MID certification mean for this meter?
MID (Measuring Instruments Directive) certification means the meter has been tested and approved according to European standards for accuracy and reliability, making it suitable for use in applications where energy consumption needs to be billed accurately.
How do I reset the partial consumption reading?
The partial consumption (resettable kWh, kVAh, kvar) can be reset using a specific button or sequence as indicated in the meter's user manual. Consult the detailed manual for the exact procedure.
What is the pulse rate for the SO interface?
The SO interface outputs 500 pulses per kWh.
What is the maximum conductor size supported?
For the main circuit, the meter supports single-wire conductors from 1.5 to 16 mm² and multi-wire conductors from 1.5 to 25 mm².
Does the LCD display have a backlight?
Yes, the Dot Matrix LCD display is backlit for improved visibility in various lighting conditions.
What is the warranty period for this energy meter?
Please refer to the official Finder warranty documentation for specific details regarding the warranty period applicable to this product model.
Troubleshooting
Display is blank / Meter not powering on
Verify that the main circuit is energized and that the voltage is within the nominal range (230/400V AC). Check all wiring connections to ensure they are secure and correctly installed according to the diagram.
Inaccurate readings
Ensure the meter is correctly wired for the system type (3-phase/single-phase) and that current direction is properly accounted for if applicable. Check that the ambient temperature is within the operating range. If issues persist, contact technical support.
M-Bus or SO communication not working
Confirm that the communication cables are correctly connected to both the meter and the receiving device. Verify that the correct communication parameters (e.g., baud rate for M-Bus) are set on both ends. Check the documentation for the connected system.
Error message on LCD display
Refer to the meter's specific technical manual for a list of error codes and their meanings. Common solutions may involve power cycling the device or checking for specific environmental conditions.
