Manual measurement modes
Overview
Loop measurements
A loop test is performed by placing both loop couplers around a loop.
If the loop couplers have been coupled incorrectly, the ExLRT will
display either a DRIVE COUPLER OPEN or SENSE COUPLER OPEN.
Correct coupling will allow the ExLRT to commence measurement.
Valid Loop measurements are displayed as a 4-digit number with two
decimal places.
If the joint measurement is not valid, the ExLRT will null the 7-segment
display and show a description of the error on the dot matrix display.
Joint measurements
A joint measurement is performed by placing the joint probes onto
any two parts of the loop circuit. The ExLRT will only validate the joint
measurement if the joint probes are attached to the loop with good
integrity and the loop couplers are coupled correctly. Valid joint
measurement will be displayed as a 4–digit number with two decimal
places.
If the joint measurement is not valid, the ExLRT will null the 7-segment
display and show a description of the error.
