7. Preliminary Procedures

a. No preliminary procedures are required to prepare the unit under test for

calibration. However, procure the following parts to fabricate a cable necessary for

calibration:

Connector, MS 3106A-14S-5S

Clamp, AN 3057-6A

Wire, copper, insulated, stranded, No. 16 AWG (20 ft long)

Spaghetti 3/4 inch diameter (4 ft long)

b. Fabricate a cable for the BEARING INDICATOR in accordance with the details in

figure 1. This cable is required to connect the BEARING INDICATOR to power and to

provide test points.

NOTE

When the performance check (a below) is within tolerance, do

not perform the corresponding adjustment (b below). When the

performance check is not within tolerance, perform the

corresponding adjustment before continuing with the

calibration procedure. When the performance check is not

within tolerance and no adjustment is specified, the deficiency

must be corrected before continuing with the procedure.
