he compact light weight design of the RD-20 makes it an ideal reference standard for field testing applications. The RD-20 may be used with a controlled current source to accurately test revenue meters. In field applications the RD-20 can perform a single-phase meter accuracy test using existing service loads. Pickups to sense meter disk rotation or calibration pulses of infrared, visible light, or KYZ signals plug directly into the RD-20. It can be utilized to test reference standards of lesser accuracy and is also an ideal standard to be intergraded within a meter test bench where lower accuracy is acceptable.
