can ow into or out of HA.
2 WA Resistor A Wiper Terminal
3 LA
Resistor A Low Terminal. The voltage at LA can be higher or lower than the voltage at HA. Current
can ow into or out of LA.
4 HB
Resistor B High Terminal. The voltage at HB can be higher or lower than the voltage at LB. Current
can ow into or out of HB.
5 WB Resistor B Wiper Terminal
6 LB
Resistor B Low Terminal. The voltage at LB can be higher or lower than the voltage at HB. Current
can ow into or out of LB.
