Portable Reference Standard

Real Companion of Meter Tester

Application

The RS 350 is a Portable Reference Standard based on latest technology in power & energy measurement. Various measuring features combined with its easy operation provide the greatest flexibility for a comprehensive on-site testing of meter installation. The equipment is offering functionality combined with an excellent menu guided operation through a 8” detachable PAD. The RS 350 is focus on the safety and various needs of metering engineers for on-site testing along with high accuracy; and meeting the latest metering standard IEC 62052 & 53 Series. The RS 350 is suitable for testing different types of energy meters (single & three phase, direct & CTVT connected), demand meters, CT Testing.
