22 ER3000 User Manual
In order to avoid producing ground loops, it may be necessary in some systems
to monitor the voltage produced across the ER3000’s internal 250 Ω resistor
rather than breaking into the 4-20 mAmp loop.

NOTE: Wire power as shown in figures 2 & 3

NOTE: Wire power as shown in figures 2 & 3
The wiring from the transducer is dependant on whether it is a 3-wire or 4-wire
transducer. Refer to Figure 4 and Figure 5 for 3-wire and 4-wire transducer
wiring schemes.
