performing an LCD test. When in the Program Mode, HART communication is not functional. There I
also an automatic time out feature. If a key is not pressed within a one minute timeframe, the transmitter
automatically reverts back to the Run Mode.
Test Ports
Loop #1 Test -- Use a multimeter set for DC mA and attach across the terminals. This puts your meter “in the loop” and
allows you to measure loop current directly, without breaking the loop.
Loop #2 Test -- Same as Loop #1 Test

must be at least a 250Ω load in Loop #1.
