
The display format for the lower/upper limit values and reference values, and unit
The lower limit value, upper limit value and reference values are construed according to the
type of display parameter or the display format.
For example, “F” is used as the unit of lower/upper limit value when displaying/sorting the
capacitance by the absolute value or deviation, meanwhile “%” is used as the unit when
displaying/sorting the capacitance by the deviation%
The following table shows the case when the lower limit value=1, upper limit value=2 and
reference value=3 are set during sorting the inductance (L).

Initializing the setting of comparator
To newly set the upper/lower limit value of comparator, it will be convenient to initialize the
setting at first.
To initialize the upper/lower limit value, select the CLEAR in the comparator setting
menu, and the following comparator initializing menu is displayed.

Completion message
Perform the EXIT operation to return to one-previous menu.
Press the
_ 1 _
key to excute the initialization, and the completion message will be displayed
for a short time, and then one-previous menu will come back.
