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.
