Instruction Sheet

Physical Installation

(for a detailed description see page 3.)

1. If required, assemble the 3-piece microphone stand (see Figure 1. on page 3).

2. Point the microphone in the direction of the pressure source.

- If required, place the windscreen on the end of the microphone.

3. Connect the microphone to the Micromate by aligning the red end of the connector with the indicated

red microphone port.

4. Make sure the Micromate has the proper Setup File (see THOR Software Setup below) and then perform a

sensor check by pressing the Sensor Check key on the keypad.

The Micromate’s Linear Microphone automates the monitoring

of air overpressure and vibration monitoring in the same

unit, making it a cost effective and flexible device for these

applications.

The Linear Microphone is calibrated to the ISEE-2017 standard

with a frequency measuring range from 2 to 250 Hertz and an

amplitude range up to 500 Pascals (0.0725 psi, or 148 dB).

Calibration

Note

: The Linear Microphone must be sent to a manufacturer certied calibration facility, or Instantel headquarters

for calibration. Please visit our calibration facility locator at www.instantel.com. Instantel recommends calibrating

all air overpressure microphones once a year and provides the Next Calibration date on the unit and sensors. The

calibration process is the only method to ensure the instrument is performing as it was designed and accurately

measuring the air overpressure it receives.

Using a manufacturer certied facility ensures the proper procedures are followed when calibrating your

microphone. This removes any uncertainty associated with the reliability and measurement accuracy of your

microphone. It also helps ensure the integrity of the measured recorded events if they are ever called upon as

evidence in a court of law. Using unauthorized facilities may have negative legal consequences if the reference

equipment is not traceable, the proper procedures are not followed or if the certication documents are

incomplete. Please visit our calibration facility locator at instantel.com.

Installing the Linear Microphone

(Taken from Section 14.4. of the Micromate Operator Manual)

The microphone installation procedures are based on ISEE eld practice guidelines for blasting seismographs.

This section illustrates the installation procedures recommended by Instantel. Your particular monitoring

activities may employ one, or a combination of all, of the following procedures.

The Linear Microphone is supplied with a 3-piece microphone stand. The top section has a clip to hold the

microphone, the extension section is threaded at both ends and the bottom section is pointed to assist in the

installation. When the three pieces are assembled the microphone stand is approximately 0.8 m (33 in) tall. If

the air overpressure is to be monitored at a height greater than 0.8 m (33 in), additional extension sections can

be purchased. (Microphone Stand Extension Rod, P/N: 400-720020-000)

Installation Steps:

1. Assemble the microphone stand at the desired location (see Figure 1.). Section 1 has a pointed tip to drive the

stand into the ground. Section 2 has a male and female thread. Screw in the female threaded end of section 2

into the male threaded end of section 1. Section 3 contains the microphone clip. Screw in the female threaded end

of section 3 into the male threaded end of section 2.

2. Push the pointed end of the microphone stand into the ground. If the ground is too hard, use a rubble mallet

to install the microphone stand.

Note

: Do not use a metal hammer or other hard object as it may damage the top of the microphone stand.

3. Attach the windscreen to reduce false triggering caused by wind. The windscreen attenuates the microphone

reading by approximately 0.2 dB.

4. Install the Linear Microphone in the clip at the top of the microphone stand and point the microphone in the

direction of the noise source.

5. Ensure that the microphone cable is securely attached to the Micromate.

6. Press the Sensor Check key on the Micromate ensuring the microphone is properly attached and has

passed the Sensor Check.
