120V Radiant Heat Film Resistance Values
Tolerances for resistance measurements are -5% and +10%. To determine nominal resistance for 120V, divide
14,400 by the total wattage. This will equal Nominal Resistance for the 120V material. Next, multiply nominalre-
sistance by 1.1 to equal the high limit. Then, multiply the nominal resistance by .95 to equal the low limit.
