The Presentor Fast Response range of analogue moving coil panel meters complements the proven and popular Industrial and Audio Level series. The range is available in three sizes each in four styles and offers a performance close to that of full specification PPM meters to meet today’s broadcast market requirement for quality at affordable prices.","Available in four sizes each in four styles, its modern flexible styling and high quality modular construction meets today’s stringent design and economic requirements.","A dc millammeter offering a performance close to that of full specification PPM meters to IEC 268-10. The general meter build conforms to relevant parts of BS89, EN 60 051 and IEC 51.","Comparison of full specification PPM meters and Fast Response Presentor range.","The response curves below give a comparison of the full specification PPM meters with that of a Fast Response Presentor 19, 29 and 39. A variation in over swing will occur from the nominal Presentor responses shown, as unlike the full specification PPM indicator where each meter is individually adjusted for ballistics, these fall within normal process parameters. In each case the FSD is 1mA. For the Presentor range the terminal resistance is 465O ±15% whereas for the PPM meter it is 600Ω ±5%.
