Local Evaluation Unit OPS

Microcomputer unit for evaluation of error of the tested electricity meter

Local Evaluation Unit OPS is the local microcomputer designed for comparison of reference impulses coming from the standard meter with optical impulses or reflexes from the black mark on the disk of the meter. Value of the measured error is displayed by the unit. The unit permits measurement of electromechanical as well as electronic meters. The built-in configuration possibilities enable to match variety of meter types and measurement requirements. Auto-calibration facility of the optical part of unit increases the work productivity eliminating necessity of manual sensitivity adjustment.

• Remotely configurable either for reflexive mark or SO output of electromechanical or LED of electronic meters
• Supplied with enhanced optical scanner working with coded signal which suppresses false light signals
• Auto-calibration capability significantly increases the work comfort and productivity of the test system
• Remotely controlled internal dividers enable evaluation of high constant meters with light impulses up to 1 kHz
• Variable pre-divider enables direct measurement of standard meters with impulse output up to 500 kHz
• Built-in menu system controlled manually via buttons enables effective local control of individual unit and data input for tests with operator interactions
