Substituters
Resistance • Capacitance • Inductance
RS • CS • LS • Series p. 1 of 2
Economical, indispensable tools for a variety
of uses in engineering, design, troubleshooting,
or service.
R-box
Best Substituter Value Available RS Series
Direct reading — No fumbling with multiple slide or Digital
rotary switches Resistance
The IET family of digital substituters uses convenient side
Substituter
by side thumbwheel switches. Simply dial in the desired
values and use.
Accurate Available from 0.01 Ω to 299,999,999.9 Ω
In addition to standard 1% economical units, tolerances of (RS-201 shown)
0.1% and 0.05% and are available.
Broad choice of standard and optional models with
many powerful features
A full line of standard substituters will satisfy most require-
ments. Other IET families of precision products include:
- Laboratory standards
C-box
- Transfer standards CS Series
- Programmable control Digital
- RTD simulation Capacitance
- High power
Substituter
- Very high resistance
Error proof Available from 1 pF to 999.9999 μF
Since the impedance values are set and read directly, (CS-300 shown)
no mistakes can be made as with rotary or slide switch
decade boxes. No need to examine and sum groups of
switches — simply read one number.
Color coded
Different colored switches separate the various imped-
ance ranges.
Compact, convenient, and rugged
Made of high impact plastic, these substituters are very L-box
portable and reduce clutter on a busy lab bench. LS Series

Programmable control (See PRS, PLS, PCS)
The RC-box, shown on the right, combines the
features and specifications of both the R-box
and the C-box in one conven ient package.
