If the point has more than one measurement, you can tap the Next and
Previous buttons to select the active measurement for which you want to view

to open the Help screen, and then tapping the Pt. Info. button.
Reviewing Signature Data
The Signature Data screen allows you to view the three types of signature
measurements: spectrum, time waveform, and magnitude and phase orders
measurements. To view signature data, tap the Sig button on the Review Data

Expand or compress the signature
You can expand and compress the Frequency/CPM axis by pressing the +/-
key. When the Enpac Ex first displays a signature, it displays the entire
frequency range or time length of the measurement. If the signature contains
detailed resolution (400 lines or more for spectra, 512 samples or more for
time waveforms), the Enpac Ex automatically compresses the data to show the
entire measurement.
IMPORTANT
The Sig button is present on the Review Data screen only
if signature data is available.
