Fig. 7.C INPUTS WIRING FOR 4-WIRE TRANSMITTER
NOTES NOTES NOTES NOTES NOTES:
1) Don’t run input wires together with power cables.
2) Pay attention to the line resistance; a high line resistance may
cause measurement errors.
3) When shielded cable is used, it should be grounded at one
side only to avoid ground loop currents.
4) The input impedance is lower than 5 Ω (20 mA input)
