The protective socket plug is supplied with a ¼-20 x 1 inch bolt which can be used to bolt the
socket to the forms. See Figure 2.
2.2.2. Installing the Jointmeter.
1. After the forms have been stripped and socket exposed, the socket plug should be
removed using the socket plug bolt or, if necessary, one of the eyebolt supplied. The
bore of the socket is supplied covered with O’lube to facilitate the assembly. Make sure
that the inside of the socket is clean and greased before proceeding.
2. Before pushing the jointmeter into the socket,
make sure that the pins in the
connector engage the slots in the plastic housing. (See Figure 3). This is very
important.

3. Remove the seal screw from the cable end flange. See Figure 1. This allows air to enter
the inside of the jointmeter while it is being adjusted.
4. Push the gage into the socket until it stops. While applying an inward pressure, rotate
the gage in a clockwise direction, for approximately 4 revolutions until the connection is
snug in the socket thread. Note: If the stiff direct burial cable is being used, the cable
bundle or reel should also be rotated to avoid crimping the cable.
Again, it is very
important that the pins in the connector are inside the slots of the PVC housing. If
the pins are not in the slots and the jointmeter is twisted the jointmeter will be
broken
.

The next step is to secure the gage body and cable in position for placing concrete.
Readings should be taken on the gage (and thermistor) at this time (see Section 3).
