difference measurement. Press the [ABS./DIF.] switch.
The display of the panel switches is changed to "DIF."
The display is changed as follows and the standard
sample input/selection menu appears.
Ｍ２０＊Ｓｔｄ Ｓａｍｐｌｅ＊ ２．０
＊＊ Ｎｏ Ｄａｔａ ＊＊
(When the standard sample data is not stored)
2 Press the [MEAS./HOLD] switch. Measurement will begin for the standard sample. When done,
the measurement data will be stored as a standard sample data.
Ｍ０１＊Ｓｔｄ Ｓａｍｐｌｅ＊ ２．０
ｘ ＝ ０．４４７６ ２．０
ｙ ＝ ０．４０７４
Ｌｖ＝８．９４０Ｅ＋０１ ｃｄ／ｍ＾２
Every time a measurement is done, the standard sample number is increased and registered
("M01 →M02 → M03 … M20"). When the number has reached 20, it returns to 01.
