blocks from the Acquisition Module.
Remove the three Acquisition Module flat head screws and split lock washers, then
remove the Acquisition Module from the Base Enclosure.
Insert the new Acquisition Module into the Base Enclosure and secure with the three
split lock washers and flathead screws.
Reattach the terminal blocks onto the Acquisition Module 1/8 inch (3 mm) flat head
screw driver for the corresponding transducer (A1, B1, A2, or B2 etc...). Make sure the
transducer wires have good contact with the terminal block and the terminal block
screws are tight. Make sure the acquisition wires and ferrules are secure and the wires
do not touch each other.
Reattach the Synchronization cable and the Acquisition cable terminal blocks.
When you have completed attaching the terminal blocks to the Acquisition Module,
check the Base Enclosure O-ring seal and reinstall if necessary.
