Cleaning
W Warning
To avoid 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.
Replacing the Battery
WWarning
To avoid false readings, which could lead
to possible electric shock or personal
injury, replace the battery as soon as the
low battery symbol ( M ) appears on the
Loop Calibrator’s display.
To replace the battery:
1. Lift and remove the battery cover to gain access
the battery compartment. See Figure 1.
2. Lift the battery from the case bottom and insert a
new 9 V battery.
3. Be sure the positive and negative battery posts
are oriented correctly, as noted in the bottom of
the battery compartment.

Disassembling and Reassembling the
Calibrator
W Warning
To avoid electric shock or personal injury:
• 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.
1. To remove the printed circuit assembly (pca):
Remove all test leads from the terminals of the
Loop Calibrator.
2. Set the rotary switch to
OFF.
3. Lift and remove the battery cover to gain access
to the battery compartment. Remove the battery.
4. Remove all Phillips-head screws from the case
bottom.
5. 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.
6. Referring 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.
7. Repeat step 6 for each of the remaining snaps that
secure the pca to the case top.
8. Lift the pca from the case top by its edges.
9. If the elastomeric strips for the keypad assembly
and LCD are stuck to the pca, remove them, but
do not touch the conductive edges.
Note
Before reinserting the pca, make sure that the
rotary knob is in the OFF position.
