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.

❺Unit (°C, °F, °K)
To accurately measure the temperature of a reflective surface, the target material emissivity which
corresponds to the measure radiant temperature must be known. The true material emissivity value
is continual changing property, and some typical values can be found on the WEB. Defining the correct
emissivity value is not an important factor for industrial application and most material surface have
emissivity values close to 0.95. SDT defines a default value between [0.95-1], customizable, that is
close to the most common materials encountered in the industrial field. In any event, since most of
the time, user is just interested in following thermal deviation or relative change, working with a
fixed/predefined value leads to an estimate of the surface temperature but there is a difference
between the real surface temperature and the measure value that is independent of the instrument
accuracy or its factory calibration. The emissivity coefficient ε refers to the radiation of heat from a
‘grey body’ according to the Stefan-Boltzmann law.

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).
Figure 16-1: example of tree structure
The SDT340 features an intuitive and quick way to navigate, going up and going down, by hierarchical
levels of the tree structure.
The list of the nodes of the selected level is placed in the upper section. Use the Right key to go up the
higher level, the parent (if exists). Its name is indicated with its path in the top section. Select the
desired node of the upper section with the Up and Down keys. Then using the right key, go down the
lower level, the children. The corresponding nodes are shown in the lower section.

❷Upper section
❸Lower section
Figure 16-2: Top, upper and lower sections
This method, common to the Free Mode, the Tree Mode and the Survey Mode, makes it easy to
navigate in between measurement types in large tree structure.
The way of proceeding is detailed with an example based on the following tree structure.

After freezing the measurement and pressing Enter, My Factory is
selected in the upper section ❶. The lower section ❷contains the
lower-level nodes of My Factory, Unit 1, Unit 2 and Unit 3.
Pressing the Right key ❸, now the upper section contains Unit 1,
Unit 2 and Unit 3. The top section ❹contains the higher-level node
of Unit 1, Unit 2 and Unit 3. The lower section contains the lower-
level nodes of Unit 1, Fan group 1 and Pump group 1.
Pressing the Down key ❺, Unit 2 is now selected. The lower section
contains its lower-level nodes: Fan group 2 and Pump group 2.
Pressing the Right key, Fan group 2 is selected. The lower section
contains Belt Drive 10, Belt Drive 11 and Belt Drive 12.
Pressing the Right key, Belt Drive fan 10 is selected in the upper
section. The lower section contains Fan and Electrical motor.
When reaching a measurement location node, press Enter.

You don’t need to go down to the measurement type level. You can directly store data from the
measurement location level by pressing Enter. In Free Mode, if the measurement type doesn’t exist, it
will be created automatically.
Naturally, you could also navigate from lower level to higher-level nodes, as demonstrate in the
following example.
Figure 16-4: Tree structure navigation (2)
Non-Drive end is selected. Pressing Left, the upper section contains the nodes having an upper level
than Non-Drive end: Fan and Electrical motor. Another Left press, the upper section is refreshed
showing Belt Drive fan 10, Belt drive fan 11, and Belt drive fan 12. After the next Left press, Fan 2 and
Pump group 2 appear in the upper section. Pressing the Down key will select Pump group 2.
