7–4 Minimate Pro Operator Manual
The unit is capable of continuously monitoring full waveform data for 24 hours; the daytime VDV
monitoring is performed on the vertical channel (7:00 AM to 11:00 PM) while the nighttime VDV
monitoring is performed on the horizontal channels (11:00 PM to 7:00 AM). The Monitor
Scheduler feature can be used to specify the different settings required for daytime and nighttime
monitoring setup files.
NOTE: Due to the processing power and decimal accuracy of a PC, performing VDV calculations
using the Blastware Human Exposure tool on a computer will typically produce a higher accuracy
result when compared to the VDV recorded in the field by the Minimate Pro unit. These results
will typically be within 5% of each other.
Tools and Materials Required:
1. Series IV Unit
2. Blastware Advanced Module
3. Instantel 1-80Hz DIN Geophone (Part No. 720A2003)
7.5. GPS [Optional]
Use the GPS (Global Positioning System) Location feature to enter location information of the
sensor and unit, relative to the blast and have them displayed on your Event Reports. GPS
devices locate your exact longitude and latitude from orbiting satellites.
Tools and Materials Required:
1. Series IV Unit
2. GPS unit must be NMEA 4800 compliant (Instantel supports the Garmin®
eTrex® handheld GPS unit).
7.6. Series IV Sound Level Microphone [Optional]
The Series IV Sound Level Microphone can perform unattended monitoring of noise, such as
building activities, construction, traffic, and mining operations. It is now possible to combine
noise and vibration monitoring on the same unit, making the Minimate Pro4™ or Minimate
Pro6™ a cost effective and flexible monitor for these applications. The microphone ships with a
microphone stand and windscreen.
The Sound Level Microphone was designed to meet the requirements for IEC Class 1, which
includes A and C weighted specifications. It has a measuring range from 30 to 140 dB with a fast
or slow response. It is also capable of recording the unfiltered response in one of two ranges, +/-
25 Pa or +/- 100 Pa. The record mode can be set to Manual trigger, Waveform (records up to 9000
seconds once a preset trigger level has been exceeded), Histogram (with intervals from 2 seconds
to 1 hour) or Histogram-Combo (Compliance mode only, this combines histogram and waveform
monitoring at the same time).
In the Blastware® Advanced Mode setup, it can also trigger and record unfiltered sound clips up
to 90 seconds long. The resulting data file can then be played back in the Blastware Advanced
Mode to help determine the source or it can be further processed, including third octave frequency
analysis.
The microphone connects directly to the overpressure channel of the Minimate Pro4 or Minimate
Pro6. For additional flexibility, the Minimate Pro6 is capable of monitoring two Sound Level
Microphones at the same time using the Blastware Advanced mode. These microphones can be
connected directly to the unit or using an extension cable up to 75 meters (250 feet) long.
