Single-Decade HARS-X Unit

SINGLE DECADE UNITS

ORDERING INFORMATION

Single-decade units are available with resis-

tance from as low as 1 mΩ per step to as high

as 10 MΩ per step. These units satisfy many

system applications requiring only a single de-

cade while maintaining all the quality features

of the HARS series.

Each decade is enclosed in an aluminum case

which can serve as a shield.

It may be panel-mounted and combined with

additional units to form potentiometer circuits

or other configurations.

Each unit consists of low-inductance resistors

in series, with a high performance solid silver

alloy contact switch.

* Use "X2" for higher power model

Options:

-RM: Rack mountable front panel for standard 19" rack

-K: Kelvin-type 4-terminal binding posts + GND

(for reduced zero resistance)

not available for 1 decade housing

-RO: Rear output
