3.9.6. Microphone Type (Compliance Module Only)
Two types of microphones may be connected to the MiniMate Plus: Linear “L” and “A” Weight.
The MiniMate Plus must be configured to the microphone type being used to ensure the proper
measurement units and data analysis techniques are used during recording. This setting tells the
MiniMate Plus which microphone you are using. To check the type of your microphone, read the
label on the side of the microphone. All Instantel microphones have a model number.
Lin Mic
identifies a linear microphone. A Mic identifies an “A” Weight microphone.
To select a microphone type, press the Right Arrow key and the Setups key together. Press the
Enter key to scroll the windows until the Microphone Type Window appears. Press Right
Arrow key to display the two microphone types, Linear or “A” Weight. To choose a setting,
display it on the MiniMate Plus display and press the Enter key. On eight channel monitors, set
the microphone type for the second microphone, Mic2.
3.9.7. Microphone Units (Compliance Module Only)
The measurement units used on the microphone channel depend on the microphone type and
measurement system being used. For Linear “L” microphones, you have the choice between psi
(L), dB (L), or pa. (L). For “A” weight microphones, units are dB (A) only. For this reason, when
you chose the “A” Weight microphone type, this window does not appear on the MiniMate Plus
display.
To choose the microphone measurement units, press the Right Arrow key and the Setups key
together. Press the Enter key to scroll the windows until the Microphone Units Window appears.
Press Right Arrow key repeatedly to display the three choices. Press the Enter key to select a
measurement unit when it appears on the display.
3.9.8. Geophone Type (Compliance Module Only)
Two types of geophone may be connected to the MiniMate Plus: a Standard Geophone or a 4.5 Hz
Geophone.
To select a geophone type, press the Right Arrow key and the Setups key together. Press the
Enter key to scroll the windows until the Geophone Type Window appears. Press the Right
Arrow key to display the two microphone types, Standard or 4.5 Hz. To choose a setting, display
it on the MiniMate Plus display and press the Enter key.
Note that for the 4.5 Hz Geophone, the unit will perform a continuity test when Sensorcheck is
run instead of the standard Sensorcheck test.
3.9.9. Geo Alarm Level (Compliance Module Only)
The Geo Alarm Level controls the triggering of an optional remote alarm (711A1401). On eight
channel monitors, the geophone alarm level operates on channels one to four only.
The remote alarm sounds two alarms: warning and alarm. The warning alarm sounds when event
activity exceeds the geophone trigger level. The Geo Alarm Level can be set to a higher level than
the geophone trigger level. This allows for the triggering of a second alarm at the higher level.
For example, in pile driving operations the remote alarm triggers a warning when activity exceeds
the trigger level for the geophone, notifying the operator that the pile driving activity has
exceeded that set level. The second alarm triggers when activity exceeds the Geo Alarm Level, set
to a higher level, notifying the operator that operations should cease immediately.
