FAQs:

Q1. What CT ratio can I configure in the AVF-19N meter?
A1. You can configure CT ratios up to 6000/5 A. For CT primary values above 975A, the display switches to kiloampere (kA) mode.

Q2. Can I use this meter for a single-phase application?
A2. Yes, it supports 1Ph-2W along with 3Ph-3W and 3Ph-4W systems, making it suitable for both single and three-phase monitoring.

Q3. How do I switch between Auto and Manual display mode?
A3. Press and hold the front key for 3 seconds, then release to toggle between Auto and Manual mode. In Auto mode, the scan time is 5 seconds.
