Leak Alarm Delay The amount of time that passes between the time a leak is detected
and the annunciation of the leak alarm.
The leak trip point must be exceeded for the duration of this delay.
Default setting: 20 seconds
Contamination
Alarm Delay
The amount of time that passes between the time a contamination
is detected and the annunciation of the contamination alarm.
The contamination trip point must be exceeded for the duration of
this delay.
Default setting: 120 seconds
Resistance Per Foot The resistance per foot (or meter) of cable determines the
LD1500’s ability to accurately detect the cable length installed and
calculate distances to leaks. Adjust this value to fine-tune the
accuracy of a distance-read leak detection system.
RLE’s orange water sensing cable has a base resistance of 2.800
ohms per foot. Most other sensing cables, including RLE’s green
chemical-resistant sensing cable, have a base resistance of 4.000
ohms per foot. Consult the sensing cable’s datasheet for further
information.
The resistance value must be entered as a 4-digit number between
2.000 and 4.250, with one number in the tens place and three
numbers past the decimal point (x.xxx).
Default setting: 2.800 ohms per foot.
Measurement

Select either feet or meters to calibrate the LD1500 to the preferred
unit of measure. All distance calculations will adjust accordingly.
