USER SETTINGS
The “User Settings” menu allows you to change your account details
including your name and password. It also allows you to adjust the
unit system and specify FFT options.
To change between English and Metric system units, use the function
buttons shown in Figure 60.
The FFT can be adjusted to either minimize data collection time or
maximize accuracy. For the shortest data collection time, choose Short
(20sec). To maximize amplitude accuracy for diagnostics and
troubleshooting, change this to Long (60sec). Note, resolution does
not change; it is fixed at 1 Hz and is not configurable.
The FFT display can also be adjusted to display in Hz, CPM (Cycles per
Minute) or Orders (multiples of shaft speed).
FFT Chart smart zoom: This feature minimizes white space on the FFT
chart. ITT Recommends leaving it enabled.
