Descriptions

Model 7550 has five precision selectable Ultra stable Current Shunts which ranges from 0.001 to 10£[. The Shunt T/C is less than 10ppm, and the internal current meter will measures from 1mA to 250Amps.
The Five selector switches, Shunts, Binding Post and the internal 4 1/2 Digit AC / DC Current Meter displays the respective shunt current. Adding an external DVM (with 5 1/2 digit or Higher) will increase both resolution and current reading accuracy.
