Meter is designed as per IS:13779 & IEC 1 D3B
Static meter is based on world's latest ASIC.
Meter is fully based on Digital Technology to improve accuracy over a wide range and to obtain stable results in all climatic conditions.
Static Meters are of Class -1.0 accuracy over a dynamic range of 500
Over load capacity is 200% of Imax. with accuracy Class 1.0 Very low starting current enables meter to record very low load consumption,
Single point calibration is provided 400% easy calibration.
Sealed counter is used to protect it from tampering.
