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.

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.
