5.2 Parameter Setting
[Aborting the Setting Operation]
Press the [MODE] key. Normally, the [MODE] key is used to move from the measurement
(<MEASURE>) mode to a mode at the operation level. It is also used to return to the measure-
ment mode from other modes.
5.2.1 Parameter Setting at Operation Level
To move to the operation level, press the [MODE] key and then enter the password (XXX). Pass-
word is not selected in first condition. When password is necessary, refer to Section 4.2 “Setting
Lists” and selected password what you need.
