20、 following convenient func- tions Disc setting mode (*1) Selection of presence of protection function during error (*2) Count function of aging cycle (*3) *1Disc setting mode: 5 discs are set before setting the aging mode. This mode makes the setting of these discs more easy. *2Self protection funct
21、ion during errors: Function which voluntarily corrects errors which occur during normal operations by retries. If this function is not provided, all operations will be stopped without retiring. It is suitable for checking errors with low reproducibility. If this function is provided, and errors can
22、be corrected by retries, aging will be continued without stopping. *3Aging cycle count function: Functions which displays the number of agings carried out on the Fluorescent indicator tube in numbers.
