JJG 495-2006Verification Regulation of DC Magnetoelectric Galvanometers (English PDF)

What this standard covers

This standard applies to the DC magnetic lines galvanometer verification procedures for DC magnetic lines of the galvanometer (hereinafter referred to as the galvanometer) of the initial verification, testing and use of follow-up inspection. This procedure does not apply to: a) the measurement process does not directly by the position of the movable part of galvanometer readings, such as optical zoom galvanometer, electronic amplification galvanometer and optical recorder galvanometer, b) attached measuring device dedicated galvanometer, c) energy constant is less than 1 �� 10 ^ (-16) Ws/mm galvanometer, d) oscillation periods less than 0. 5s galvanometer.
