Section 3: Meter maintenance

Maintenance and Troubleshooting Manual

January 2018

3-9000-772 Rev B

Use a 3/16 inch screwdriver and loosen the transducer cover screws enough to remove

the cover and gasket.

Figure 3-14 LT-07 Transducer assembly removed from transducer housing

Loosen the cord grip nut and if necessary, use a 7/16 inch wrench to hold the hex nut in

place while turning the cord grip nut.

Disconnect the transducer cable wires from the terminal block.

10.

Pull the cable wires out of the transducer.

11.

Set aside the nut and grommet you received with the replacement transducer

assembly.

12.

Insert the transducer cable into the replacement transducer.

13.

Apply a light coat of Loctite® anti-seize nickel grade lubricant (20g stick-37230) on the

transducer cover screw threads.

14.

Ensure the threads are properly aligned (avoid cross-threading the transducer cover).

A. Transducer cable

B. Transducer enclosure, terminal blocks and cable wires
C. Transducer assembly

D. White or red mark indicating white wire connection point
