Resistance substituter

Model  Description 
RS CS LS  Resistance, Capacitance and inductance substituter
 Inductance Substituter.


A full line of standard substituters will satisfy
most requirements.

 - Laboratory standards
 - Transfer standards
- Programmable control
- RTD simulation
- High power
- Very high resistance
 Substituter Capacitance
Error proof
Since the impedance values are set and read
directly, 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 im ped - ance ranges.
Compact, convenient, and rugged Made of high
impact plastic, these sub sti tut ers are very portable
and reduce clutter on a busy lab bench.

* Accuracy after subtraction of the Residual Impedance; traceable to NIST.
LS-400 and LS-400A Test Conditions: 1 kHz; 1 Vrms; series model; 23°C.
** Higher power resistance substituters (1 W or higher) available; see optional models below or
HPRS data sheet.
† Residual Impedance may be reduced to 0.04 Ω or 5 pF for lowest decade with LR Option.
This makes for more effective usage at low impedances. Lowest decade is isolated from others
with a switch when desired.
