FR-D800 Analog Frequency Meter Connection and Calibration Instructions

This document explains how to connect and calibrate analog frequency meters from predecessor models (KY-452, YM-206NRI) to the FR-D800 inverter series via the new terminal AM, replacing the former terminal FM. It covers calibration procedures both with and without an 8.2 kΩ resistor, including parameter settings (Pr.55, Pr.158) and precautions for zero-point adjustment.
