Configuring the 4-20 mA
Analog Input
To configure the 4-20 mA analog input, access the setup menu as
described on page 5-4 and complete the following steps:
The Test Submenu
To test the analog input, program a test value into the XDP analog
output (see page 5-6) and connect the analog output signal to the
analog input terminals. Then, proceed as follows:
At the next prompt, the mA value of the test signal is shown.
The Trim Submenu
To trim the analog input, make sure the XDP analog output has been
calibrated (see page 5-5) and connect the XDP analog output signal to
the analog input terminals.
The XDP analog output is now driven to exactly 4 mA.
