You are checking the supply chilled water temperature thermistor probe on a high-pressure hermetic centrifugal chiller. Using the illustrated chart, what statement is true if the supply water temperature is verified 45 ° F with a digital thermometer. |
A) When checked with control power on and the thermistor probe connected into the circuit, the thermistor probe voltage drop should be 11.416 volts. |
B) When checked with control power on and the thermistor probe isolated, the thermistor probe voltage drop should be 3.805 volts. |
C) When checked with control power on and the thermistor probe connected into the circuit, the thermistor probe voltage drop should be 3.805 volts. |
D) When checked with control power off and the thermistor probe isolated, the thermistor probe voltage drop should be 3.805 volts. |
