EQUIPMENT Model #DB62 - S/N 21201900062A

Dekabox DB62 Decade Resistor

Contact NAPT staff to purchase this Decade Resistor $750.00

These Decade Resistors are primarily intended for precision measurement applications where their excellent accuracy of ±0.01%, stability, and low zero resistance are important. The esi DB62 Dekabox In-Line Decade Resistor provides dependable long-term service in precision DC through audio frequency applications. Six decades of non-inductive, precision, wire-wound fixed resistors are mounted in a low noise shielded aluminum housing.

The esi DB62 decade resistor is easy to use. The input terminals and a case connected ground terminal are conveniently located on the front panel. The dials rotate independently through 360 degrees to simplify and speed settings. This allows for a coarse approximation and then precise finer steps to provide an exact resistance value.
