Local evaluation unit OPS

is the microcomputer unit for error evaluation of the tested electricity meter.

•  Sensor works with coded signal making it resistant against
   the external light influence;
•  Calibration capability of the unit optical part enables adjustment
   of the sensors for various disc types and LED automatically;
•  Variable pre-divider enables direct measurements of standard
   meters with impulse outputs up to 500 kHz and evaluation
   of high constant meters, with light impulses up to 1 kHz;
•  The built-in manual switch enables effective local individual units
   control and data inputs for tests with operator interactions.
