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.
