1. Safety
Read carefully the manual before using the SDT340. To prevent death or injury risks and a severe
damage to the unit and its accessories, use only as specified in this manual. Otherwise, the protection
provided by the instrument might be impaired. Make sure that all instructions are fully understood
and observed.
To avoid personal injury:
•Do not use if damaged.
•Use caution around rotating equipment and keep cords and straps contained.
•Select a safe location for the sensor and proceed with utmost care during its mounting when
taking readings on exposed rotating parts.
•Do not operate around explosive gas, vapor, and dust or in damp or wet environments.
•Use proper protective equipment, as required by local or national authorities, when working
in hazardous areas.
•Comply with local and national safety requirements when working in hazardous locations.
•See emissivity information for actual temperatures. Reflective objects have lower emissivity
and might pose a burn hazard.
•Never look directly to the laser beam. Never point the laser beam at a person's eye. Do not
aim the laser at specular reflection surfaces. Never look the laser using an optical instrument.
The power supply should be only operated at an ambient temperature between 0°C to 45°C up to 95%
relative humidity, no condensation. Its storage temperature is between -40°C to +70°C (-40°F to
+158°F) 10 to 95% relative humidity. The power supply should never be operated or even stored at
places listed below, because this could lead to operating failures:
•Places heavily exposed to moisture or where water condensing may occur.
•Places subject to constant vibrations or to high temperature fluctuations.
•Outdoors.
2. Caution
Do not disassemble the instrument, the sensors, the battery, the battery docking station and the
battery power supply. Do not attempt internal alterations. Do not attempt any repairs. Potential
damages will not be covered by the Lifetime Warranty. Contact SDT Ultrasound Solutions or an SDT
Authorized Service Provider.
The permissible ambient temperature range for the operation of the SDT340 is -15 °C to +60 °C (14 °F
to 140 °F). Relative humidity must be less than 90%, non-condensing.
Due to the typical self-discharge rate of NiMH batteries it is recommended to charge the battery at
least every 3 months, even if it is not used. It is recommended not to store an uncharged battery for
more than a few weeks. This would significantly reduce its life span.

16. Tree navigation and data storage in Free Mode
The example hereafter uses the following UAS tree structure:
Unit 1 ❺, Unit 2 ❻and Unit 3 ❼are the children of My
Factory ❽. They have the same level in the tree structure. In the
same way, Centrifugal pump 1, 2 and 3 are children of Pump
group and have the same level. Fan group is the parent of Belt
Drive fan 1, 2 and 3…
Belt Drive fan ❶should be considered as machinery. Fan ❷
and Electrical motor are the components of one machinery.
Drive end ❸and Non-Drive end are the measurement locations.
A measurement location is namely the contact sensor place or
the target for non-contact probes. For instance, the bearing
housing or pillow block is measurement locations when using the
accelerometer or the RS2T.
Acc100 [10-1k] ❹as a measurement type.
A measurement type is the combination of a technology (Acc
means vibration accelerometer), a sensor sensitivity (100 means
100 mV/g) and a specific setting ([10-1k] means a measurement
bandwidth between 10 Hz and 1 kHz).
