Operating Restrictions during Integration

• If there is a power failure while integration is in progress, the integrated value and
integration elapsed time will be backed up. When the power is restored, the display
will show the integrated results up to the time the power failure occurred.
• To start integration after the power is restored, it is necessary to reset integration first.
Certain key operations are restricted during integration, and are shown below.
