R-"DECADES"   and  an   -"OCTADE"
and   R/C "SUBSTITUTION BOXES"

[ A ]   "DECADE"  of  SWITCHABLE  RESISTORS
» MONACOR «

( BODY   =   6_1/4" x 4_1/8" x 1_3/8"   ;   16 cm x 10.5 cm x 3.5 cm )



RESISTORS:   1%   /   1 Watt
RANGE:   1 Ohm   ...   > 11.11 MOhm  in  1-Ohm-Steps
When ALL SWITCHES DOWN, Resistance on OUTPUT = ZERO
Example shown:   ( 20 + 30 + 200 + 300 + 2K )  ==>>  2.55 KOhm


[ B ]   My  MINI-R-DECADES  ( published 1981 ) ...

(left)  UNIT-1  =  Low Range   =   x0.1 ... x100  KOhm ...                                     



                                     ... (right)  UNIT-2  =  High Range   =   x0.1 ... x100  MOhm

RESISTORS:   5%   /   0.5 ... 1 Watt


[ C ]   My  MINI-POWER-R-"OCTADE"  ( published 1983 ) ...



RESISTORS:   10% / 10 Watt
1  /  2  /  4  /  8  Ohm   +   10  /  20  /  40  /  80  Ohm

RANGE:   1 Ohm   ...   165 Ohm  in  1-Ohm-Steps
( with  CABLES  and  SHORT-CUTs )


[ D ]   R- & C- SUBSTITUTION  BOXES ...



RESISTORS:   1 Watt
Ranges = 100 ...680 Ohm   /   1 ... 680 KOhm

CAPACITORS:   400 VDC ... 1 KVDC  /  160 VAC ... 400 VAC
Ranges = 100 ... 680 pF   /   1 ... 6.8 nF   /   10 ... 68 nF   /   0.1 ... 0.68 μF

====================================================================
"Substitution-Boxes" are useful in Electronic Labs ... EXAMPLES:

 (1) ReCALIBRATION of a repaired Multimeter's OHM-RANGE
 (2) Repairing old VacuumTube-Radios: Finding the "RIGHT UNIT" ...
     ... or to REPLACE a burned/unidentifyable RESISTOR
 (3) Physics LECTURES in schools, e.g. "RC-Timing" Experiments -
     or a RELAY-TIMER as an Experiment on "Electro-Magnetism"
 ...
