Raising the Standard in Electric Meter Test Equipment

In addition, this accessory will give the user the ability to perform a CT burden added test along with the 3 Series exclusive burden measurement test. Its compact size allows the 335, the 3 Series, and all standard accessories to be stored in the same carrying case. With the added functionality of the 335, the lightweight 3 Series is truly a step above.
