For a better understanding of the appropriate connection when using the instrument
to simulate current into industrial 2-wire loop please, note the meaning of the terminal
used.
Passive loop
This type of connection is to be used when the external loop is not equipped with the
loop power supplied. The calibrator can be, as an example, connected directly to a
recorder, controller, etc. with input circuits configured for current measurements.
Active loop
This type of connection must be used when the external loop is equipped with its
loop power supplied. The power supply is not required to be disconnected. The loop
circuit must be opened and the calibrator connections are placed in series on the
loop.
