Resistance Box (Dial Type)
(EE - 502) |
Resistance Box Dial Type : The dial studs are machine cut
from phosphorous bronze and laminated bush contact are
made from hardened copper phosphot bronze leaves. The
laminated bushed are connected to the main central
contact. Individual resistors are mounted separately. The
values of resistors are machine engraved or Screen Painted.
Technical Details : Double covered Eureka wire is wounded
on Bakelite spools. Each resistor is processed for ageing
and heat treatment to avoid shifting of the values and
tested individually to accuracy after fixing Carbon
Resistance. Resistance are calibrated on imported testing
Bridge Accuracy +0.1%
