If measurement values are unstable due to noise influences, change the grounding for
the shield in the following order for stable measurement.
(1)
RTD
(Pt100)
(2)
RTD
(Pt100)
(3)
RTD
(Pt100)
Supplementary
To minimize the influences of the wire resistance, be sure the wire
length to be same of each cable from the terminal nA , nB or nC to
RTD.
