1 Safety notes
To avoid possible harm, read and follow these instructions.
DANGER: Risk of electric shock, fire, or property damage
Drilling a structure may damage a dangerously live electric cable or a pressurised pipe. Before
drilling a structure, make sure the structure doesn’t contain dangerously live cables or
pressurised pipes. If their existence cannot be excluded, the whole installation containing the
structure should be de-energized and de-pressurised before drilling begins. In some cases, a
decrease in locating accuracy may move the intended drill point.
ATTENTION: Risk of locating error due to electromagnetic conditions
Large metallic objects, radio transmitters or industrial equipment may degrade locating
accuracy or may prevent locating completely. Before attempting to locate a drill hole, take care
that there are no large metallic objects at or near the intended drill hole. Large metallic objects
include radiators, sheet metal, foil, and wire mesh among other things. Shut down or move any
radio transmitters that actively transmit on the same frequency at least 10 m away from the
intended drill hole. This includes other drill point locators.
ATTENTION: Risk of locating error due to device misorientation
Locating drill points with misoriented devices may degrade locator performance. Instructions
for properly orienting the devices are provided in section 4: Operating receivers.

4 Operating receivers
4.1 Inspecting the work site for hazards
Carefully examine the structure to be drilled and surroundings for hazards before drilling.
DANGER: Risk of electric shock, fire, or property damage
Drilling a structure may damage a dangerously live electric cable or a pressurised pipe. Before
drilling a structure, make sure the structure doesn’t contain dangerously live cables or
pressurised pipes. If their existence cannot be excluded, the whole installation containing the
structure should be de-energized and de-pressurised before drilling begins. In some cases, a
decrease in locating accuracy may move the intended drill point.
4.2 Objects that may decrease locating accuracy
ATTENTION: Risk of locating error due to electromagnetic conditions
Large metallic objects, radio transmitters or industrial equipment may degrade locating
accuracy or may prevent locating completely. Before attempting to locate a drill hole, take care
that there are no large metallic objects at or near the intended drill hole. Large metallic objects
include radiators, sheet metal, foil, and wire mesh among other things. Shut down or move any
radio transmitters that actively transmit on the same frequency at least 10 m away from the
intended drill hole. This includes other drill point locators.

User Manual Vesala PK2 Receiver X2.0 ENG
14 (22)
Locating accuracy will be degraded if there are large metallic objects closer to the units than the
distance between the units is. Additionally, distance display may indicate longer distance than
actual. To avoid locating errors when large metallic objects are present, consider another drilling
location, perform offset measurement or multi-point measurement.
4.3 Locating accurately thru thick structures
ATTENTION: Risk of locating error due to device misorientation
Locating drill points with misoriented devices may degrade locator performance.
Alignment errors are highlighted when locating drill points thru thick structures. When using
Transmitter PKT2 with Receiver PKR2 for straight drilling, the device bottoms should face each
other on parallel planes both sides of the structure. When wedge pieces are used for angled
drilling, the angle of both transmitter and receiver should be the same and they should be at the
same angle to the horizontal. If necessary, use a spirit level to align the wedges.

15 (22)
User Manual Vesala PK2 Receiver X2.0 ENG
Respectively, when locating SmartPlug SP15 or Plug
Transmitter TX15, the receiver should be used perpendicular
to the transmitter. Notice this especially when the transmitter
has been installed in an angle to the structure.
4.4 Operating the receiver
Place the receiver against the structure with the user interface
towards the user. Move the receiver slowly to the direction
indicated by red arrows. Two arrows pointing to a direction
indicate a long distance, one stands the proximity of the
measured point. The audio signal pitch increases when the
receiver is moved towards the correct spot. Green squares
indicate when the receiver is aligned with the transmitter.
When only four green squares are displayed on the receiver,
the transmitter and receiver are aligned and the distance
between them can be read on the display. The spot can now be
marked through the receiver's centre hole.

4.5 Measurement at an angle
When a drill point needs to be located at an angle other
than 90° to the surface of a structure, start by attaching
the transmitter to the structure at the desired angle of the
drill hole. Locate the transmitter while holding the
receiver at an equal angle. A wedge made from a non-
metallic material may be used to hold the devices at the
desired angle. If the angles are not identical, the resulting
hole should be drilled from both sides of the structure so
that the holes meet inside the structure at different
angles.

User Manual Vesala PK2 Receiver X2.0 ENG
4.6 Offset measurement with PKR2 and PKT2
Place the transmitter on an area where no
metal is present. Measure the distance and
direction from the receiver to the intended
drilling point. Locate the corresponding
spot relative to the transmitter on the other
side of the structure and use reverse
measurement to define the drilling point.
4.7 Multipoint measurement with PKR2 and PKT2
Measure at least two, preferably four points at exactly same distance from the intended drilling
point. Make separate measurements and markings for each
reference point. The
correct drilling spot is at
the geometrical midpoint
of the reference points.
