I want to check the correctness of 4-20mA signal in my measurement loop. When I connect the multimeter (in series) in the negative line it shows 16 mA. Whereas on connecting the multimeter (in series) in the positive line it shows 0 mA. The transmitter reading varies as per the process requirement.
Please help me as I am confused.
