5.2 Connecting the measuring unit
5.2.1 Supply voltage
Taking 4 to 20 mA test signal
A 4 to 20 mA test signal may be measured via the test terminals without interrupting the
measurement. To keep the corresponding measured error below 0.1%, the current measuring
device should exhibit an internal resistance of < 0.7 .
5.2.2 Terminals
• Supply voltage and internal ground terminal: 0.5 to 2.5 mm
2
(20 to 14 AWG)
• External ground terminal: 0.5 to 4 mm
2
(20 to 12 AWG)
5.2.3 Cable specification
• Endress+Hauser recommends using twisted, shielded two-wire cables.
