I I - PRESENTATION OF THE EQUIPEMENT
The TEPEX 2S is designed to control the position of mine holes before charging the explosive
; it allows a direct measure of the bench thickness : distance separating the bore hole from the
frontal face.
The kit is made up (see fig. 1) of a transmitter probe introduced into the bore hole and a
reading box held, at distance, in front of the frontal face.
The reading box integrates a distancemeter to measurement traversing.
A laser telemeter comes in addition.
Fig. 1 - Reading box held vertically, operator elbows to body
The reading box, associated with the emitting probe, is used to measure the total distance
- t.d (distance separating the probe from the reading box) ;
The laser telemeter measure the distance - l.d- separating the rock massif from the box.
The measurement - d- from the bench results in the difference between the two measures.
The TEPEX 2S is appropriate for quarries and civil engineering.
The measurement range stretches from 2,5 m to 15 m.
This measurement is expressed in meters (m) and by centimeters (cm) up to 6 m, by 2 cm
from 6 to 8 m, by 5 cm from 8 to 10 m and by 10 cm over and above 10 m.
The centimeters display doesn’t represent the precision of the measurement, but makes the
search easier for the minimum thickness by indicating the direction of the variation.
The accuracy of the measurement stays inferior to 5% of the scale total.
NOTE: TEPEX 2S is not affected by a certification and a labeling under the legal metrology : it enter not into
categories of instruments regulated by decree n° 2001-387 of 3 May 2001 or in the category of material
measures or dimensional measuring instruments mentioned in annexes to directive 2004/22/EC of
31/03/2004 on measuring instruments.
The TEPEX 2S is made up of the following elements :
a transport case,
a measuring box,
a probe,
a laser telemeter to measure the distance separating the rock massif from the operator,
a graduated rope.
a sound device to control the good working of the probe

I II - TECHNICAL SPECIFICATIONS
THE PROBE :
Diametre: 50 mm - Length : 450 mm - Weight : 1,2 kg
Body made of polymer. Equipped with a ring allowing for it to be attached.
Around 20 hours of autonomy in real live situation.
Transmission of information “low battery” to the reading box
Waterproof under 20 m of water.
Use of accus forbidden
Verify the right shutting of the stainless cap before use.
Not forget to take off the battery after use.
THE READING BOX :
Dimensions : 210 x 105 x 55 mm –Weight : 0,6 kg.
Box made of 3mm thick polycarbonate, protected against dust and water projections in all
directions.
Inclined screen adapted to the vertical hold of the box.
Automatic stopping.
USB liaison for transmission of measures to PC.
THE ELECTRIC POWER SUPPLY :
The probe and the reading box are both supplied by a 9V alkaline battery, 6LR61.
Use of accus forbidden.
THE LIMITS OF USE :
The TEPEX 2S use an electromagnetic signal which can be disrupted by the material
being gone through or the type of environment.
The disruption remains negligible as long as the rock contains little or no metallic mineral
elements and the level of interference remains that of a quarry blasting zone.
WARNING
The TEPEX 2S is built to function from -15°C to +35°C. Use in extreme
temperatures provokes a surcharge of consumption above normal.
The TEPEX 2S is an instrument of measure which must be conserved and used
as such. In particular, excessive force applied to the probe, dropped too quickly
in the hole, or a fall, can provoke the break up of the aerial.
In case of doubt of normal usage, check the accuracy of the measurements with
the help of a graduated ribbon held between the probe and the box, held
vertically at about 1,5 m from the ground. A difference of measurement superior
5% indicates a disfunctionment of the TEPEX 2S.
Choose a testing ground outside of the concrete flag stone and away from possible
parasites, for example, computers and their screens.
The TEPEX 2S is designed to control the drilling which takes place before the
introduction of the explosive charge.
Under no circumstances can the TEPEX 2S be used as an instrument associated
with the handling of explosives.

I I III - THE EMITTER PROBE
The probe is realized in polymer and is equipped with a ring that allows the attachment.
A screw cap provides access to the housing of the 9 volt battery.
To ensure a maximum sealing of the battery housing, take care that the seal
surface stays clean and in the right position.
The cap must be tightened correctly.
The probe’s power supply cuts automatically when the probe is in horizontal
position or when the voltage is insufficient.
The information « low battery » is transmitted to the reading box.
The rope provided is graduated every meter from the bottom of the probe. It
measures the depth of the borehole.
Advice of use :
The user can introduce the bore in a sheath to allow its extraction in case of jamming in a
borehole. So, as the bore is jamed the user can take it out of the sheath by pulling the
fixing rope.
The tube can be composed of a standard Post sheath diameter 60 mm joined to the bore.
The 3 grooves allow to tighten differently according to the real diameter of the sheath.

I IV - THE READING BOX
It is equipped with an LCD display (2 lines with 16 characters) and three keys (see diagram
below).
I V - THE LASER TELEMETER
The laser telemeter measures the distance between the rock massif and the reading box. A
function subtracts a fixed distance for 5m to the measured distance between the reading box
and the probe.
The use of a laser telemeter allows a safe distance between the operator and the coalface.
A visible laser beam identifies the target point. The scope is 30 m with an accuracy of 2 mm.
For all information, see the instructions in the description of the laser telemeter.
Don’t throw the used batteries. Keep them and return them in the collection sites.
The trap door of the battery chamber is
situated at the back of measuring box.
To open, unscrew the two screws with
the help of a flat screwdriver.
The electric power supply of the reading
box is guaranteed by a 9 volts battery.
The reading box contains an autonomy
of around 4 hours on continual use.
A screwdriver is supplied with the unit.

9 volts battery
