SECTION 8
CALIBRATION
8.1 Calibration Required
The calibration is performed as the preventive maintenance to prevent the MG3641A/MG3642A performance from
reducing.
The calibration is required when the inside of this device need periodically be adjusted to maintain the MG3641A/
MG3642A performance even if the MG3641A/MG3642A itself operates normally.
If an item that does not satisfy the calibration standard is detected, contact out service division.
