3.7. Start Monitor Key
Press this key to enter the monitor mode. The MiniMate Plus is now waiting to record an event.
In manual record mode, the unit will display the following message when you press the Start
Monitor key: “Press ‘*’ to start, Cancel to abort.” Press the Enter key to begin monitoring.
You can view previously recorded events while the monitor is in the monitor mode. See the
section describing the Event key, page 3–7.
3.8. Setups Key
The setups configure the MiniMate Plus to record events. The functions accessed by this may
change from one monitoring session to another. You can change the MiniMate Plus setups using
the keyboard or using a personal computer running the BlastWare III software. This section
outlines the procedures to change the setups using the MiniMate Plus keyboard. For information
on how to change the setups using a personal computer, refer to the BlastWare III operator
manual.
3.8.1. Record Mode
A record mode determines how the MiniMate Plus records events. The MiniMate Plus offers the
following recording modes:
a. Single Shot Record Mode
Use single shot record mode to record one event automatically. The MiniMate Plus records the
event, displays the results, and stops. No further recording occurs. Recording begins automatically
when an event’s ground vibrations or air pressure exceeds the trigger level. See below for
information on the trigger level.
b. Continuous Record Mode
Use continuous record mode to record multiple events automatically. The MiniMate Plus records
an event, displays the results, and continues to monitor, ready to record following events. The
MiniMate Plus records all events whose activity exceeds a preset trigger level. See below for
information on the trigger level.
c. Manual Record Mode
Use 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.
d. Histogram (Strip chart) Record Mode
Use the histogram record mode for long–term recording periods such as monitoring pile driving
operations. Histogram record mode operates with both four and eight channel monitors. Four
