Supplies for Installation

Included with the LDCE

Leader cable
Meter leads

Install the 9V Battery

If you are using the LDCE for the rst time, install the
9 volt battery (not included with the LDCE) as follows:

1. Screw in the two lock-down screws on the front
cover using a 1/16” (1.59mm) allen wrench.

2. Remove the two push button caps. Lift the cover
and insert the battery.

3. Loosen the lock-down screws of the LDCE until
they are ush with the bottom cover.

4. Replace the push-button caps for each screw you
just loosened.

Test the LDCE Battery Voltage

If you have used the LDCE before and have never replaced the 9-volt battery,
test the battery before testing the sensing cable. To test the battery:

1. Connect the LDCE meter leads to your multimeter, as follows:

• Connect the red lead to the Voltage (V) input.

• Connect the black lead to the Common (COM) input.

Important! - Do not connect the leads

to the wrong inputs, or you will blow the
multimeter’s internal fuse.

SeaHawk sensing cable

Available from Other Vendors

Multimeter with mA capability
9V battery to power the LDCE (battery is NOT included with LDCE)

Please Note:

The LDCE can only test for cable contamination or detected leaks. It cannot
test for a broken cable, and it cannot be used to verify that bulk cable has had
connectors properly installed.

2. Set the multimeter to VDC. If the
multimeter is not auto-ranging, set it
to the 20VDC scale.

3. Push the System Check button on
the LDCE and note the reading on
the multimeter. If it is less than
8VDC, change the LDCE’s battery.

To test the LDCE’s battery, connect it to the

multimeter as shown.

Test the SeaHawk Sensing Cable

The LDCE can test one cable or a string of cables, up to a total length of 5,000
feet (1,524m). To test the SeaHawk sensing cable for contamination:

1. Power down the SeaHawk controller. Disconnect the sensing cable to be
tested and separate the white leader cable from the sensing cable.

2. Connect the LDCE’s white leader cable to the sensing cable you wish to test.

3. Connect the LDCE meter leads to your multimeter.

• Connect the blue lead to the milliamp/microamp input (mA/mA).

• Connect the black lead to the Common (COM) input.

Connect the LDCE, the sensing cable, and the multimeter as shown.

Important! - Do not connect the leads to the wrong inputs, or you will blow the

multimeter’s internal fuse.

4. Set the multimeter to mA and to ADC. If the multimeter is not auto-ranging,
set it to the 200mA scale.

5. Push the Cable Test button and record the meter reading. A reading of less
than 25mA is acceptable. A reading greater than 25mA indicates the cable is
contaminated or has detected a leak. You may need to separate mated pairs
of cable into individual segments and test each section individually to isolate
the problem cable.

Note: The LDCE can only test for cable contamination or a leak detected. It

cannot test for a broken cable.

6. If your LDCE has been in service for some time, check the accuracy of the
test current coming from the LDCE by pressing the System Check button.
Ensure that your meter displays a reading of approximately 180mA. If the
reading is not close to 180mA, change the battery in the LDCE and retest.
