Cleaning
W Warning
To prevent electrical shock, remove test
leads and input signals before cleaning.
To clean the case, wipe it with a cloth lightly
dampened with water and a mild detergent.
Do not use abrasives, solvents, or alcohol.

Do not allow water into the case.
Remove any input signals prior to
removing test leads and opening case.
When servicing the Loop Calibrator,
use only specified replacement parts.
To disassemble and reassemble the Loop Calibrator,
refer to Figures 2 and 3 as necessary and perform the
following procedure.
Note
Both a Phillips-head screwdriver and a flat-
blade screwdriver are required.
Removing the Printed Circuit Assembly (PCA)
1. Make sure the Loop Calibrator is off.
2. Remove all test leads from the terminals of the
Loop Calibrator.
3. Gently pry the rotary knob off with a small flat-
blade screwdriver.
4. Lift and remove the battery cover to gain access
to the battery compartment an se screws d 2 ca
inside. Remove the battery.
5. Remove all Phillips-head screws from the case
bottom.
6. Separate the case top from the case bottom.
Verify that the battery terminals are being guided
through the bottom case before completely
removing the case bottom.
7. R eferring to Figure 3, insert a small, flat-blade
screwdriver between the edge of the case top and
the PCA. Gently unsnap the case top from the
PCA.
8. Repeat step 7 for each of the remaining snaps that
secure the PCA to the case top.
9. Lift the PCA from the case top by its edges.
10. If the elastomeric strips for the keypad assembly
and LCD are stuck to the PCA, remove them, but
do not touch the conductive edges.
