Current Measurement Parallel to a Test Diode, Connections

The impedance of MC5P’s milliampere input is low enough to enable current measure-
ment parallel to a test diode in a 20 mA circuit. Connections:

Plus Side Test Diode

Minus Side Test Diode

MC5P parallels the test diode of the transmitter and measures the
externally supplied output current of the transmitter. For more infor-
mation concerning test diode connections of HART instruments,
see Appendix 1, chapter

Connecting MC5P and a HART Instru-

ment

on page 138.

Note.

In higher temperatures: The leakage of the diode in the instrument
may affect the accuracy.
