Resistance Taper

More Info
									   Resistance Taper


 Resistance Taper
With the shaft (lever) placed in the specified position, resistance taper shall be determined by measuring the voltage
between the specified terminals (between terminals 1 and 2 or between terminals 2 and 3)and calculating the
percentage in reference to the voltage between terminals 1 and 3.
Reference: Standard resistance tapers in reference to rotational angles (travels) are as shown below.
