3. With one hand over the PCA, roll the top case over (face up) and lift it away from the
PCA.
Two red and one black plastic shields are used to isolate the user from the
input terminals. With the PCA removed, these shields are loose and can fall
away from the PCA.
4. Remove and set aside all three shields for use during reassembly
To avoid risk of electrical shock, make sure the plastic input
terminals are properly positioned on the PCA before attaching it
to the top case.
To install the PCA, proceed as follows:
1. With the PCA face-up, place all three plastic shields into position on the PCA.
2. Lower the top cover onto the PCA, and roll both parts over (PCA up).
3. Connect (snap) the chrome plated springs to the INSULATION terminals.
4. Install the screw that attaches the PCA to the top case.
With the PCA removed, the final step in disassembling the Meter is to remove the LCD
assembly from the PCA. Refer to Figure 5 and use the following procedure to remove the
LCD assembly:
1. Remove the two screws from the display end of the PCA.
2. Hold the PCA face down with the fuse-end of the PCA toward you. Locate the
screw-hole near the center of the assembly. This hole is the one used to attach (with a
screw) the PCA to the top case.
3. Now, locate the gray plastic tab just above and to the left of the hole. Using your
thumbnail press the tab down and toward the display end of the PCA. This will
release the LCD assembly from the PCA.
To avoid damaging the plastic guide pins on the LCD assembly,
keep the LCD assembly parallel to the PCA when separating the
two parts.
4. Without tilting the PCA, lift it straight up and away from the LCD assembly.
5. To keep loose parts from falling away from the LCD assembly, keep it face-down,
and set it in a safe place.
