Instrument Description

Each key is labelled according to its primary function. The area immediately above
certain keys contains a secondary key function that can be activated by first pressing
[2
nd
F]. Throughout this document, references to a secondary function are written as
follows: [2
nd
F], [Primary] (Secondary). For example, the instruction to activate the
gain adjust function is written as follows:
Press [2
nd
F], [] (Gain).
The [], [], [], and [] keys, along with the [ENTER] key, are used to select menu
items or display parameters, and to change parameter values. Use the [MEAS] key at
any time to return to the measurement screen. The yellow keys are related to
calibration.
