What is the formula for calculating the percentage of a process variable (%PV) in a system with a 0-10 V voltage loop?
A. %PV = (V/Vspan)100%
B. %PV = (V/Vspan)10%
C. %PV = (V/Vspan)5%
D. %PV = (V/Vspan)1%
Answer:A

A. %PV = (V/Vspan)100% B. %PV = (V/Vspan)10% C. %PV = (V/Vspan)5% D. %PV = (V/Vspan)1%
Explanation: The percentage of a process variable (%PV) in a system with a 0-10 V voltage loop can be calculated using the formula %PV = (V/Vspan)*100%, where V is the voltage, and Vspan is the span of the voltage loop in volts.
