REMARKS: 1. Resistance and resistance tolerance were tested in-house with micro resistance meter.
2. Coating refers to UL-certified data provided by supplier

Remark:

Max. Resistance Value:
Max. resistance value is given to calculate the minimum resistance value because resistance value is proportional to the length of resistive wire wound along the ceramic rod.

Rated Wattage: Power rating at Max. Resistance Value.

Resistance Tolerance: Precision range of Max. Resistance Value..

1. Power Rating of adjustable resistor is determined by the maximum resistance value.
2. Resistance and Power Rating should be decreased while you are moving the adjustable lug.
3. Adjustability is 10% to 90% of full value. Wattage is proportional to this adjusted resistance value.
