12. Test procedures 12.1 Examination of product—mechanical The gyro shall be inspected visually and dimensionally for proper identification, surface finish, and for defects in workmanship to determine that it conforms to the requirements of subclause __________. 12.2 Examination of product—electrical Inspect the gyro electrically according to the following subclauses to measure insulation resistances, impedances, and dielectric strength. For gyros where preamplifiers or other sensitive devices are included within the gyro case, care should be taken to avoid the application of voltages that could damage those devices. 12.2.1 Insulation resistance 12.2.1.1 Purpose of insulation resistance test The purpose of this test is to measure the insulation resistance between the isolated circuits and between the gyro case and the circuits isolated from the gyro case. 12.2.1.2 Insulation resistance test—equipment In addition to the standard operating equipment from 11.2.2, the following test equipment from 11.2.3 is required for this test and should be listed in this clause:a) Megohmmeter 12.2.1.3 Insulation resistance test—setup and procedure Apply __________ V dc ± __________ V dc for a period of __________ s ± __________ s between the indicated circuits and between the circuits and the gyro case. Record the resistance reading.
