Test Point Terminals (TP2, TP3)
– Test meter terminals are
provided within the transmitter housing on the lower portion
of the printed circuit board (see diagram) for measuring
the output signal without disturbing the signal loop. Do
not connect any device or meter whose internal resistance
exceeds 20 ohms across these test points. Also refer to “In-
Process Zero/Span Adjustment” in the following section.
Test Meter Posts are visible just below zero and span
potentiometers (see illustration).
