6.1.2 HART™ resistance configuration
Due to internal 250 Ω resistance of the CEP1000 it is possible to use Rosemount 275
Communicator during calibration or installation of a HART™ transmitter. The internal
resistance replaces the resistance of 250 Ω required normally for the communicator
model 275. To activate this function if necessary, the internal jumper must be removed.
The instrument is supplied with an inserted jumper (see figure 2). To activate the resist-
ance, remove the jumper. The jumper can be either stored outside of the instrument or
just plugged onto a contact pin in the instrument, thus, the circuit is interrupted.
-J8 (HART™ JUMPER)
Remove the jumper to activate the HART™
resistance (250 Ω).
Figure 2
If the 250 Ω resistance is activated, it is possible to energise a
maximum load of 950 Ω instead of 1200 Ω . In most cases this would not
cause any problems for the calibration of products incompatible with
HART™.
