The Sigma Series DS series measures DC current or voltage, suitable for all DC systems. Scales are linear and customized to customer needs and specifications. For special high accuracy meters to better than 1 %, scales are hand marked and critically calibrated to achieve the desired accuracy. High currents are measured with separate shunts and suitably scaled indicators. Suppressed, center and offset zero models are available. Meter movement is spring-loaded and suspended between sapphire jewels with hardened steel pivots. The movement is critically shielded and dampened with silicon oil for smooth deflection without pointer vibration.
Scales are easily interchangeable for maximum scaling flexibility. The scale display area allows for the use of large, easy to read numerals and divisions. The Sigma Series DS comply with DIN EN60051 (IEC51) requirements, with a standard accuracy of ±1.5% of full scale or better. The Sigma Series DS is available as 48, 72, 96 and 144 mm sizes and is manufactured from self-extinguishing polycarbonate.
