(2) Recording Mode
The record mode sets how the monitor records Events. To choose a recording mode, click on the
Recording Mode drop-down menu and select a record mode. Refer to the Minimate Pro
Operator Manual for more information on the data displayed on the monitor during recording.
Choose one of the following recording modes.
i Waveform
Use Waveform record mode to record multiple Events automatically with no dead time between
Events. The monitor records an Event, displays the results, and continues to monitor, ready to
record following Events. The monitor records all Events whose activity exceeds the preset trigger
level.
ii Waveform Manual
Use Waveform Manual record mode if automatic triggering is unreliable, due to excessive wind
or nearby vehicle activity, or to record the background noise level in the vicinity of a site.
Recording can be initiated from the Unit Monitor Status dialog.
iii Histogram (Strip chart)
Use the Histogram record mode for long-term recording periods such as monitoring of pile
driving operations. Histogram record mode operates with both four and six channel monitors.
In Histogram record mode, the monitor stores summary information in intervals. The monitor
continues to sample data continuously at the chosen sample rate but only stores the relevant peaks
for the interval. This reduces the data recorded and greatly increases the monitor storage capacity.
For each interval, the monitor calculates the maximum peaks, the frequency of the largest peak,
and the peak vector sum. For each channel, the maximum peak and its frequency are calculated.
Also the largest peak vector sum is calculated over the entire Event. Histogram record mode
displays the peak of each interval in a bar chart, while tabular format represents the peaks as
numbers. You are able to capture up to 800,000 intervals. Examples: 18.5 days at 2 second
intervals, or 555 days at 1 minute
iv Histogram Combo
Histogram Combo record mode creates a waveform during Histogram recording if the signal
exceeds the waveform trigger level. The waveform Event is saved as a separate file while the
Histogram Event file remains continuous. Depending on the amount of data collected and the
sample rate, you are able to capture thousands of full waveform records while simultaneously
recording in histogram mode. Example: 30 days of Histogram recording at 1 minute intervals, and
over 7500 1 second waveform events.
