The Triaxial Borehole Geophone is designed to be lowered
into a borehole to measure vertical, transverse and longitudinal
ground vibrations.
Each Triaxial Borehole Geophone is coupled with a Micromate
Base Unit and calibrated to the same industry standard as the
Micromate Base Unit, namely:

INSTALLATION
Physical Installation
Installing the Triaxial Borehole Geophone requires a minimum borehole diameter of 76.2 mm (3 inches).
1. Thread a steel cable through the Triaxial Borehole Geophone’s mounting eyelet bolt and bind securely.
Note: DO NOT use the connecting cable to lower or raise the geophone as this may damage the cable.
2. Point the arrow located on the top of the geophone in the direction of the event.
3. Maintain this orientation while lowering into the borehole and ensure that the geophone is at a 90° angle.
4. Once positioned, connect the Triaxial Borehole Geophone cable and run a sensor check.
5. Maintaining the geophone’s 90° angle, carefully ll in the hole with cement, grout, or sand to secure its
orientation.
6. Repeat the sensor check to ensure the sensor has not moved and all channels still pass the test.

Example Installation
1. Prepare the borehole geophone
by wrapping the connections with
electrical tape to keep them clean.
2. Drill the borehole and slide the
borehole geophone into place.
3. Fill around the borehole geophone
and cable with gravel pack.
4. Fill the hole with cement. 5. Hole lled with connectors ready. 6. Borehole geophone location clearly
marked with monitoring unit placed
in a secure lock box.
Monitoring Unit Setup
Conguring a Micromate Base Unit (ISEE, DIN, SWB, SWP) with a Triaxial Borehole Geophone follows the
same procedure as the Standard Triaxial Geophone. For complete details, please refer to the Micromate
Monitoring Unit Operator Manual and THOR Software Operator Manual.

Warranty
Instantel products come with a limited one-year warranty against defects in materials or workmanship unless otherwise stated.
The warranty begins on the date of shipment from the Instantel factory to the customer and is subject to certain exclusions and
conditions as stated below. Monitoring units and sensors will have the warranty extended for a second year if they are returned to
the Instantel factory for service and calibration within 30 days of the ‘Next Calibration’ date printed on the calibration label located
on the product.
If, within a period of one year from the date of shipment to a customer, the instrument fails to perform in accordance with
Instantel’s published specications under normal use and operating conditions, it will be repaired or replaced at the sole discretion
of Instantel free of charge. Components subject to fair wear and tear in regular use, as solely determined by Instantel, are excluded
from this coverage. This warranty will not apply if the damage or malfunction occurs due to (i) adjustments, additions, alternations,
abuse, misuse or tampering of the instrument; (ii) instrument operation or use contrary to the operating instructions; (iii) power
fluctuations; or (iv) any other cause not within the cause or control of Instantel. If inspection by Instantel fails to disclose any defect
covered by this limited equipment warranty, the instrument will be repaired or replaced at customer’s expense and Instantel’s
regular service charges will apply. This warranty is non-transferable.
Any shipments returned directly to Instantel must have prior approval, and all packages must display the Return of Material
Authorization (RMA) number issued by Instantel. Shipping charges to Instantel’s factory will be paid by the customer and return
shipment to the customer will be paid by Instantel.

Registration Form, within ten days of purchase. Products will be assumed out of warranty if no warranty card is on le at Instantel.
Retain this warranty statement and the proof of purchase for your records.
Except for the foregoing limited equipment warranty, Instantel makes no other warranties and hereby disclaims and excludes all
other warranties, whether statutory, express or implied, whether arising under law or equity or custom or usage, including any
implied warranty of merchantability, tness for a particular purpose, non-infringement, satisfactory quality, or quiet enjoyment,
and any warranty that the product supplied may not be compromised, or that the product will in all cases provide the function for
