coil resistance tests at the sensor junction box to eliminate the possibility of faulty cable. The readings
for each coil pair should match at both ends.
4. Test the terminals in the sensor junction box for shorts to case.
a) Leave the terminal blocks disconnected.
b) Remove the lid of the junction box.
c) Testing one terminal at a time, place a DMM lead on the terminal and the other lead on the
sensor case.
With the DMM set to its highest range, there should be infinite resistance on each lead. If there is
any resistance at all, there is a short to case.
5. Test the resistance of junction box terminal pairs.
a) Test the brown terminal against all other terminals except the red one.
b) Test the red terminal against all other terminals except the brown one.
c) Test the green terminal against all other terminals except the white one.
d) Test the white terminal against all other terminals except the green one.
e) Test the blue terminal against all other terminals except the gray one.
f) Test the gray terminal against all other terminals except the blue one.
g) Test the orange terminal against all other terminals except the yellow and violet ones.
h) Test the yellow terminal against all other terminals except the orange and violet ones.
i) Test the violet terminal against all other terminals except the yellow and orange ones.
There should be infinite resistance for each pair. If there is any resistance at all, there is a short between
terminals.
Postrequisites
To return to normal operation:
1. Plug the terminal blocks into the terminal board.
2. Replace the lid on the sensor junction box.
Important
When reassembling the meter components, be sure to grease all O-rings.

15.33 Locate a device using the HART 7 Squawk feature

The Squawk feature causes the device to show a specific pattern on its display. You can use this to locate or
identify a device.
Restriction
The Squawk feature is available only with HART 7 connections from the Field Communicator. It is not available
with ProLink III.
