1. Safety

Carefully read the manual before using the instrument. To prevent death or injury risks and 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. SDT340 is designed to meet the safety regulations. However, safety can be at risk if the

equipment is used by unqualified staff, used improperly, or not inspected and maintained.

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

•Do not used the SDT340 in hazardous environments (ATEX environment). Please refer to the

SDT270A (Ex proof version) and its marking before considering these restricted areas in the

field.

•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 is designed to operate at ambient temperature between 0 °C to 60 °C (32 °F to +140

°F) up to 90% relative humidity, no condensation. Its storage temperature is between -20 °C to +85 °C

(-4 °F to +185 °F). 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 (5 °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, using only the provided charger pack. It is recommended not to store an

uncharged/unused battery for more than a few weeks.

The SDT 340 is equipped with a class 2 laser: risk of eye injury

•Never look directly to the laser beam

•Never point the laser beam at a person’ eye

•Do not aim the laser at specular reflective surfaces

•Never view the laser using an optical instrument

Ultrasound inspectors using SDT instruments with audio outputs are exposed to sounds levels having

noise exposure characteristics daily, which, if not managed by the manufacturer, can increase your risk

of hearing loss. Legislation in Europe has fixed a threshold at 80 dB(A) for a maximum exposure of 8

hours per day.

The audio output paired with the Peltor headsets supplied by SDT, having the references FUHDPH-1

and FUHDPH-2 delivers a maximum sound pressure level of 79 dB. SDT makes an additional safety

guarantee to our users. When connecting a sensor, or selecting/changing sensors, SDT instruments

self-adjust the volume to a default, maximum sound pressure level of 58 dB typical. This applies to all

compatible, SDT manufactured sensors and is done so, willingly for the protection and safety of anyone

who uses our products.

9. Data Collection Modes

Before recording data, you must first install the driver, create a tree structure from UAS 3 or UAS Lite

and upload it from your PC to the instrument.

The SDT340 features 3 modes of data collection:

The Free mode –the user selects a sensor; the measurement settings and choose the recording

location freely inside the tree structure. If the measurement type doesn’t exist, the SDT340

dynamically creates it.

The Tree Mode (for UAS3, UAS Lite users only) –the user first selects at his own discretion a

measurement location and then select an existing measurement type. The user is not allowed to

change the measurement settings or create a new measurement type inside the tree structure.

The Survey Mode (for UAS3, UAS Lite users only) –the device proposes a filtered list of measurements

to collect in a predetermined order. The user is not allowed to change the measurement settings or

create a new measurement type inside the tree structure.

Refer to the paragraph “Tree navigation and data storage in Free Mode” to see the definition of a

measurement type.

Caution:

Measurements can only be stored at the Node level/Measurement point
