The PowerMaster 4 Series Automated ANSI Meter Tester boasts many features that make it the most functional, versatile, and user-friendly meter tester on the market today.

It is a closed-link meter testing solution that sources current up to 30A or 50A (depending on model) and operates on all voltages up to 530V with no switch changes required. It also facilitates testing of most ANSI socket based meters using our newly-engineered universal zero insertion force meter socket.

All this functionality comes in a field-rugged case yet is still the lightest product in its class by a wide margin. With models featuring internal reference standards of 0.04% accuracy, there is a 4 Series Automated Meter Tester available to fit virtually any need, all with a 2-year warranty.
