HC SD series are a true digital setting meter relays with the dual 4 digits Hi & Lo setting. Eight decade setters are divided into 2 setting groups as the presets of input. The digital compactor performs a very accurate setting within 1 count error maximum & operates stable, independent of draft for all related factors in setting version.
