Capturing Peak Values

Pressing the softkey labeled Stop ends the peak recording
session. The summary information in the display freezes and the
softkeys change function to allow saving the collected data.
Pressing the softkey labeled Close exits the peak recording
session without saving the collected data.
Note
Turning the rotary switch before saving the peak
recording data will cause all the accumulated data to
be lost.
To save peak screen data, the peak capture session must be
ended by pressing the softkey labeled Stop. Next press the
softkey labeled Save. A dialog box opens where the default
saved name can be selected or another name assigned. Press
the softkey labeled Save to store the Peak screen data. Peak
capture can not be continued at this point. Press the softkey
labeled Close to exit the Peak capture mode.
Pressing the softkey labeled Restart while the peak recording
session is running stops the session, discards all peak recorded
data, and immediately starts a new peak record session.
When viewing saved records, snapshot peak records look the
same as a stopped peak records. Therefore, use the elapsed
time (average value time stamp) to identify one record from
another.
To extend battery life during peak record, the Meter enters a
battery-saver mode after a period of time set for the Auto Off
feature. See the “Setting Backlight and Auto Off Timeouts”
section for more information on the battery saver mode.
