Answer / nikhil patil

While transmitting the signal the concept of active and
live zero is used.Generally 1V to 5V is standerd signal
range.voltmeter will read 1v when input to the system is
minimum (active zero)and voltmeter will read 0V when wire
is disconnected.Hence troubleshouting becomes easy.

Answer / ravi gandhi

As per my thought ,

1 > Sensor is there in feild , that will give Temp reading
in Volt / Resistance that will fetch by TT (Temp
Transmitter)when the wire is disconnected & Volt meter is
showing 0 Volts that means two leads of wire may be
shorted .Even o\p of TT is 4-20 mA Voltmeter reading will O
Volts inplace of 1-5 Volts .

TS --- >> TT ----- > Voltmeter(Connected perellel)
