4-20 mA Output Connections
Connections for the 4-20 mA transmitter output are made to the
connector terminals labeled MA OUT. The 4-20 mA output may be
powered internally or from an external power supply.

Analog Output Power Supply
If the analog output is not using the 24 VDC supply to power the output
loop, it can be used for other things. The I+ Terminal is the +24 V and
the R terminal is the return.
F4 Digital Input Connections
A digital input, F4, is standard on the meter. This digital input is
connected with a normally open contact across F4 and COM, or with an
active low signal applied to the F4.
The functionality of the F4 input is set up in the Advanced Features,
User
menu.
