10 Pressurized Line Leak Detection Pressure Offset
10-10
DETERMINING A PRESSURE OFFSET VALUE FOR EACH TRANSDUCER
Press MODE to display DIAGNOSTIC MODE, then FUNCTION until you see the message:
From the PLLD Diag message, press STEP until you see the display below
Press ENTER and the results of the last test displays (‘No Test Data Available’ message appears if this is the first
test):
Press STEP:
To start the test, press ENTER. During the test this message appears:
The Pressure Offset test results message appears when the test ends:
You can print out the test result if you have an optional printer. If you do not have a printer, record the offset value
for the transducer. Press TANK/SENSOR and repeat the above procedure for all installed transducers.
The maximum offset pressure range is ±5 psi (±34.5 kPa). If a Pressure Offset is greater than ±5 psi (±34.5 kPa),
repeat the test. If the Pressure Offset is again out of range, either the line pressure is not completely vented or
there is a hardware problem. Refer to PLLD troubleshooting procedures for further instructions.

Press STEP until you see the message:
Press CHANGE and enter the Pressure Offset value for transducer Q1. If necessary, press the left arrow key to
change the sign (+ or -). Note: enter the Offset value exactly as displayed in the Offset test result message
(including + or - sign). Press TANK/SENSOR, to display another transducer. Press CHANGE to enter its Pressure
