PROGRAMMING THE SDT43
7.1
PROGRAMMING WITH HAND HELD TERMINAL
When using HART® or a Hand Held Terminal (HHT), a minimum resistance of
250 Ω
must
be
present in the loop of the 2-wire system. This is necessary for proper communication (see
drawing below). A power supply of at least
17 Vdc
must be used.
The SDT43 can easily be programmed with the Hand Held Terminal (HHT) from the HART®
Foundation (type 275 or 375 HART® Communicator).
Option 1
: HART® Handheld terminal connected across the transmitter.
Option 2
: HART® Handheld terminal connected across the loop resistor.
