3-2. Disassembly and Reassembly

TO AVOID ELECTRICAL SHOCK, REMOVE TEST LEADS AND
ANY INPUT SIGNALS BEFORE OPENING THE CASE.
To avoid contamination from the fingers, handle the pca by the
edges or wear gloves. PCA contamination can cause failures in
humid environments.
This meter contains components that can be damaged by static
discharge. To avoid damaging these components when
servicing the meter, take precautions indicated on the "Static
Awareness" at the beginning of Section 3.
Referring to Figure 3-1 as necessary, disassemble the meter as follows. A Phillips-head
screwdriver and small flat-blade screwdriver are required.
1. Remove the test leads and set the slide-switch to OFF.
2. Remove the Phillips-head screws (H1-4) from the case bottom (MP8).
3. Separate the case top (MP2) from the case bottom.
4. TO REPLACE THE BATTERY: Lift the battery from the case bottom and insert a
new 9V battery (NEDA 1604, 6F22, or 006P). Be sure the positive and negative
battery posts are oriented correctly.
5. TO REMOVE THE PCA (A1): Insert a small, flat-blade screwdriver between the
edge of the case top and the pca where shown in Figure Gently unsnap a side of the
case top from the pca. Repeat on the other side of the pca. Unsnap the case from the
top of the pca last.
6. LIFT THE PCA FROM THE CASE TOP BY ITS EDGES. If the elastomeric contact
strips (J3, J4) for the switch assembly (S2) and LCD (U3) are stuck to the pca,
remove them without touching the conductive edges.
TO REINSERT THE PCA: Important: First make sure that the slide-switch actuator
(MP5) and slide-switch (S1) are both in the OFF position. Place the pca over the
four screw posts in the case top, then press gently on the center of the pca while
using the small flat-edge screwdriver to shoehorn the pca under the snap on a side
of the case top. Repeat on the other side and the top.
7. TO REMOVE THE SWITCH SUPPORT (MP6): Hold the case top with the face of
meter in your palm and press on the slide-switch actuator (MP5) to dislodge the
switch support. Lift out the switch support.
