Please take care when meeting this symbol:

GENERAL INFORM A T I O N

The MicroSonde MPL7-33 is small battery operated transmitter that emits a 33 kHz
signal, which can be located by a receiver operating on the same frequency. The
Sonde is intended to be used in non-conductive ducts, cavities and structures. The
device is intended for professional use.

ITEMS SUPPLIED

1 MicroSonde Transmitter MPL7-33

2 Lithium Battery BR535

1 Case with Quick Reference Guide SB7

BATTERY INSTA LLA T I O N , T U R N I N G O N A N D OFF

Figure 1: Inserting battery

Insert a BR535 battery. Observe polarity (Figure 1). To turn the MPL7-33 on, tighten
the battery compartment. The LED at the tip of the MicroSonde will start flashing.
Take care to fully tighten to avoid water getting into the device. To turn the Sonde
off, unscrew battery compartment. Always remove the battery completely when
you are not using the Sonde.

When the battery has insufficient capacity left for carrying out measurements, the
LED will turn off. Replace the battery. Low temperatures reduce the operating time
of the battery.

High mechanical stress, high ambient temperatures or immersion into liquids
can cause leakage, fire or explosions of the batteries.

Precautions: Protect the batteries from mechanical influences and high ambient
temperatures. Do not drop or immerse batteries into liquids.

OPERATING THE DE V I C E

When the battery is inserted and the battery compartment attached, the
MicroSonde will start emitting a 33 kHz Signal. The location of the MPL7-33 can now
be detected with a receiver that operates at the same frequency, such as the
Vesala CL43. Before use, ensure the MicroSonde is fully functional by locating the
signal with a corresponding receiver. Refer to the user manual of the receiver on
pinpointing the location of the MicroSonde.

You can attach the MicroSonde to a duct rod, cable rodder, snake rod, push or
pull rod using the female M6 thread at the end of the battery compartment. An O­ring provides added grip when tightening.

When using the device for blowing with compressed air, always blow with battery
compartment end first. Refer to the user manual of the blowing unit and follow safe
work practices.

Use of compressed air can lead to the MicroSonde exiting the duct at great
speed.

Precaution: Always use a catcher at the end of the Duct. If changing the direction
of the blowing due to the device getting stuck, remember to move the catcher to
the other end of the duct. Do not blow the MicroSonde with pressure exceeding 6
bars. Always use safety goggles, when using the MPL7-33 with compressed air.

MAINTENANCE

CLEANING

Clean with clean soft cloth. Do not use abrasive agents or solvents for cleaning.
Take care to avoid dirt getting into the unit. Regularly inspect O-ring and replace if
damaged. If water gets into the battery compartment, allow it to dry at room
temperature.

STORAGE

Store inside storage box. Respect the temperature limits stated in the technical
data when storing the device. Always remove the batteries from the product
during storage to avoid leakage. After a long time of storage, check the function
of the device.
