1 Safety notes
To avoid possible harm, read and follow these instructions.
DANGER: Risk of death, personal injury, or property damage
Attaching the device to an elevated position may be dangerous if the attachment fails. Notice
that moisture, dirt, surface properties, ambient temperature or aging may reduce the reliability
of the supplied adhesive putty or affect the amount of adhesive putty required to reliably attach
the device to a surface. If possible, restrict access to the hazard zone under the device when the
device is attached to an elevated position. Always secure the device with additional supports if
the device is attached to an elevated position, and it is possible that persons or animals may
enter the hazard zone under the device. When the device cannot be reliably secured and the
hazard zone under the device cannot be completely restricted, it is required that anyone
entering the hazard zone under the device wears adequate personal protection equipment.
Always remove the device 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.

WARNING: Risk of electric shock, fire, or property damage
When scanning a structure for live cables with the device, notice that the effective range of the
voltage detector is limited, and scanning should be done from both sides of the drilled structure
before drilling begins. Certain materials or structures may block the electric field of a
dangerously live cable and render the voltage detector ineffective. Only cables that are live at
the time of scanning may be detected with the voltage detector.
ATTENTION: Risk of property damage
When scanning a structure for pipes with the device, notice that the effective range of the metal
detector is limited, and scanning should be done from both sides of the drilled structure before
drilling begins. Only metallic pipes may be detected with the metal detector.
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.

4 Operating Transmitter PKT2
4.1 Inspecting the work site for hazards
Carefully examine the drilled structure 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 Locating hazards with Transmitter PKT2
Transmitter PKT2 includes both metal and voltage detectors. Place the transmitter against the
surface of the structure and move it slowly around the intended drill spot. Do this on both sides
of the structure. When the metal detector or voltage detector LEDs turn on, it may be an
indication of metal or a dangerously live object nearby. The more LEDs are illuminated and the
higher the pitch of the sound indication, the closer or larger the object is.
WARNING: Risk of electric shock, fire, or property damage
When scanning a structure for live cables with the device, notice that the effective range of the
voltage detector is limited, and scanning should be done from both sides of the drilled structure

User Manual Vesala Transmitter PKT2 X2.0 ENG
before drilling begins. Certain materials or structures may block the electric field of a
dangerously live cable and render the voltage detector ineffective. Only cables that are live at
the time of scanning may be detected with the voltage detector.
It is recommended to test the voltage detector on a known cable before scanning structures to
familiarize oneself to the response and performance of the voltage detector. Construction
materials often reduce the effective range of the voltage detector compared to the range in air.
ATTENTION: Risk of property damage
When scanning a structure for pipes with the device, notice that the effective range of the metal
detector is limited, and scanning should be done from both sides of the drilled structure before
drilling begins. Only metallic pipes may be detected with the metal detector.
It is recommended to test the metal detector on a known, exposed structure before scanning
hidden structures to familiarize oneself to the response and performance of the metal detector.
4.3 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

User Manual Vesala Transmitter PKT2 X2.0 ENG
14 (20)
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.
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.
4.4 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.
4.5 Attaching Transmitter PKT2 to structures
DANGER: Risk of death, personal injury, or property damage
Attaching the device to an elevated position may be dangerous if the attachment fails. Notice
that moisture, dirt, surface properties, ambient temperature or aging may reduce the reliability

User Manual Vesala Transmitter PKT2 X2.0 ENG
of the supplied adhesive putty or affect the amount of adhesive putty required to reliably attach
the device to a surface. If possible, restrict access to the hazard zone under the device when the
device is attached to an elevated position. Always secure the device with additional supports if
the device is attached to an elevated position, and it is possible that persons or animals may
enter the hazard zone under the device. When the device cannot be reliably secured and the
hazard zone under the device cannot be completely restricted, it is required that anyone
entering the hazard zone under the device wears adequate personal protection equipment.
Always remove the device before drilling.
The supplied adhesive putty may be used to attach the Transmitter PKT2 to a dry, clean and
solid surface. The putty has working temperature range of +15…+30 °C Use other attachment
methods outside this temperature range or when the surface is wet or dirty.
When using other attaching methods, do not hang Transmitter PKT2 directly from a nail or a
screw. Metal objects inside on near the centre hole degrade locating accuracy. Instead, attach
Transmitter PKT2 to a piece of string and hang the string from a nail or a screw.
Place the device against the structure with the user interface towards the user. Place the centre
hole of the transmitter on the reference point to be transferred.
Do not leave the transmitter attached for extended times because the attachment may fail.
Before drilling, remove the transmitter from the structure to avoid damage or falling.
