A high current test set is designed with high current, low voltage outputs used for many purposes, including primary injection testing of direct acting low voltage circuit breakers, motor overload relays, current transformers and heat runs. It also can be used as a general purpose adjustable voltage or current source.

The front panel displays provide simple indication of output current, time, and system status. The keyboard provides easy control of output.

• 4 output ranges to accommodate various impedance loads
   
• Digital memory ammeter with special firmware for true-rms continuous and pulse current reading with high accuracy
   
• Automatic pulse (memory) mode provides fast and accurate evaluation of output current pulses as short as one half cycle
   
• Autoranging timer with LED readout provides four digits in seconds or cycles mode, with a resolution of 0.001 second or 0.1 cycle
