6. INTRODUCTION
DYNAMIC STAR is an professional indicator, ergonomic, extremely versatile and simple to use for measures FORCE, WEIGHT,
PRESSURE, TORQUE, DISPLACEMENT, SPEED and POWER. It is equipped with an input for strain gauge transducers and an input for
incremental encoder (optional). DYNAMIC STAR is particularly suitable for applications where it is requested high capture rate (up
to 19,2kHz) that a high resolution (± 200,000 divisions to 2mV/V for static measurement). DYNAMIC STAR can be connected with up
to 7 different strain gauge transducers. After being configured the instrument automatically recognizes the strain gauge sensor
connected and self-configures the dedicated parameters (Unit, filter, resolution).
Internally, the microcontroller processes the signal from the strain gauge sensor through an 32bit analog to digital converter at a
conversion frequency variable from 2.5Hz to 19,200kHz making DYNAMIC STAR adaptable to any application that may require both
high resolution (in static applications) that high sampling rate (dynamic applications).
The incremental encoder input can manage quadrature signal type line driver RS422 (A +, A-, B +, B-), open collector or 5V TTL (A,
B). DYNAMIC STAR allows to manage both rotary and linear incremental encoders, determining position and speed informations in
different units.
In combination, the informations of force and speed, allow you to determine the Power Mechanics (Force*Speed for linear and
Torque*Revolutions per second for rotary systems) that can be displayed in different units.
The display is via a large LCD graphic display with backlight.
DYNAMIC STAR can detect PEAKS, lock the display with HOLD function and via the internal data logger can record up to 266,000
measurements at programmed intervals or manually by the REC.
DYNAMIC STAR can store acquisition points at maximum speed 19,200kHz for a time of about 13s. The storage can be affected by a
trigger HW or SW to better define the time interval of the test. The measurements are stored in non-volatile memory, which retains
data even when the power down.
Measurements can then be downloaded via the powerful software Winstar for creating graphs, export to Excel, report printing etc.
The USB output allows the real-time communication of data acquired through a simple communication protocol. DYNAMIC STAR is
seen by a PC as a virtual COM port.
To reduce battery consumption, DYNAMIC STAR can be programmed to turn off after a set time (from 1 to 99 minutes).
The backlight of the LCD display has three levels of intensity to adapt to all lighting conditions outside.
Moreover DYNAMIC STAR can be configured to display the LCD normally or upside down.
The instrument is powered by a rechargeable Li-Ion battery of high reliability that is recharged directly from the USB port.
The main features are:
•HIGH RESOLUTION DISPLAY graphic LCD with 3 levels of backlight and display upside down
•AUTOMATIC SELECTION OF UP TO 7 EXTERNAL strain gauge transducers of force, pressure, torque, displacement.
•Incremental Encoder input for measuring position and speed (option)
•CALCULATION OF MECHANICAL POWER
•HIGH FREQUENCY ACQUISITION up to 19,200kHz
•UP to +/- 200,000 divisions for static measurements (at 2 mV/V)

DYNAMIC STAR USER GUIDE MO.DYNAMIC STAR.R3.EN
Pag. 9
REC KEY
Pressed for about 4 seconds run the start / stop a cycle of data logger.
The proper acceptance of the button may be controlled through the appearance of the icon on the display.
If the manual acquisition mode has been selected, each short press of the key stores a measurement point.
BACKLIGHT and REVERSE KEY
This key has a double functionality.
Pressed for less than 1 second toggles the backlight intensity on 3 levels.
Pressed for about 4 seconds switches the display type of the display from normal to reverse.
In reverse mode, the display of the main page will appear as shown below.
17. POWER MEASUREMENT
DYNAMIC STAR can measure at the same time the force and the speed through an incremental encoder. So it is suitable for the
measurement of mechanical power for both linear and rotary systems.
In the case of linear systems, the power in watts is defined as force*speed where the force is expressed in Newtons and the the
speed in m/s.
For rotary systems the power in Watt is defined as 2π*Torque*speed where torque is presented in Newton*m and the speed in Hz.
DYNAMIC STAR displays the mechanical power as an alternative to the measurement of force or torque.
The units are: Watt, kWatt and lb*ft/s.
In order that DYNAMIC STAR can properly measure the mechanical power it is necessary to follow the following recommendations:
For the power measurement it is necessary that the option incremental encoder input is present and that this is
enabled in the Main Menu -> Setup STAR.
In the Setup Page of the current channel (see chapter dedicated to calibration of a channel strain gauge) Power should
be selected as channel type (as an alternative to the options: Force-Pressure-Torque-Displacement).
The calibration of the force transducer or torque (respectively for linear or rotary) must be performed (see chapter on
the calibration of one channel strain gauge):
•In Newton for transducers Force
•In Newton*m for torque transducers
Speed measurement (relative to the incremental encoder) must be set in m/s for linear encoders and Hz for rotary
encoders Main Menu -> Unit.
DYNAMIC STAR then performs the necessary calculations to calculate the mechanical power and to perform the necessary
conversions units of the Power.
18. MAIN PAGE

DYNAMIC STAR USER GUIDE MO.DYNAMIC STAR.R3.EN
Pag. 10
The main page shows the value of the measure according to
the settings made in the calibration pages of the transducer.
In the event that it is enabled only the strain gauge channel the
main page page it looks like in the figure. The writing CH: X (X
ranges from 1 to 7) indicates which transducer is currently
connected and recognized.
In case DYNAMIC STAR was equipped with the option of a
encoder channel and this is enabled the main page looks like in
the figure on the right.
It displays also the value of the encoder channel in the selected
unit.
The values are displayed on a field of up to 8 digits including the sign and decimal point.
If the number to be displayed in some situations is greater than 8 digits (including the sign and decimal point), the value is
automatically scaled to one decimal place.
Examples :
Value Display
1. +100.0000 100.0000
2. - 100.0000 -100.000
3. [phone] HHHHHHHH
Example 1. The value to be displayed is +100.0000.
Because the + sign is not displayed the value is within the allowable digits.
Example 2. The value to be displayed is -100.0000. The value consists of 9 digits counting the point and the sign.
It is scaled by a a decimal point position to be represented number
Example 3. The value to be displayed consists of 9 digits. The value cannot be displayed.
It is given the error message HHHHHHHH.
Depending on the configuration on the main page DYNAMIC STAR may appear several icons that describe the functional status of
the instrument.

If this message appear please recharge the battery immediately.
If this condition persist for more than 2 minutes DYNAMIC STAR will be automatically turned off.
19. ZERO FUNCTION
The ZERO funcion is activated by the dedicated key ZERO and it is used to clear the indication of the strain gauge and
the encoder channels.
The function acts on all the measuring range (100%).
The ZERO is stored and will conserved also upon a new power on of the instrument.
When the function is active the icon ZERO is displayed.
Each time the ZERO key is pressed a new ZERO is performed.
To remove the actual ZERO, keep pressed for 4-5 seconds the ZERO key. The icon ZERO will be cleared.
In PEAK mode (when the AUTORESET function is disabled) the ZERO key clears the peak value and allow to start a new PEAK test.

DYNAMIC STAR USER GUIDE MO.DYNAMIC STAR.R3.EN
Pag. 12
20. PEAK FUNCTION
The PEAK function is used to display the maximum (PEAK +) or
minimum (PEAK-) of a dynamic measurement.
DYNAMIC STAR allows to select the function PEAK+ o PEAK-.
The icon PEAK+ or PEAK- on the display shows which PEAK is
active.
See the picture aside to verify how the PEAK+ (POSITIVE) and
PEAK+- (NEGATIVE) works.
The PEAK function is activated with the dedicated
button.
Entering the main menu or turning the power off function is
automatically disabled.
PEAK values can be reset manually using the ZERO key or
alternatively automatically, activating in the Menu
Parameters page the function AUTO RESET. When the
function AUTO RESET is active the display shows the message
RESET.
The automatic RESET of the PEAK is activated when, after detecting a peak, the measure returns to its initial value.
The icon RESET will start to flash and once the time is elapsed, set in the Menu Parameters, the peak value will be reset allowing
the beginning of a new test.
Always in the Menu Parameters you can enable the detection of the First Peak.
In this mode, it is identified as valid only the first peak detected (maximum value followed by a fall of the load). A PEAK THRESHOLD
parameter (expressed as a percentage of the full scale currently-used) allows to discriminate a falling load valid by other (lower
value) that may be due to noise or other.
The figure below allows you to better appreciate how the peak detections work with the First Peak activated.
First Peak Detection
When the detection of the first peak is disabled the PEAK value is the highest value measured during the test.

21. DATA LOGGER FUNCTION
For the setting of the datalog parameters see the dedicated chapter Main Menu -> Data Logger.
Pressing REC for 4-5 seconds the a datalog cycle start and the icon will appear.
Each time a acquisition point is stored the icon ◼appear for 1 second.
The start of a cycle can be conditioned by a HW trigger (through a line of the input external connector) or by a software Trigger. The
trigger software allows you to start actually recording when the measurement on the strain gauge channel exceeds a certain value
setting in Main Menu -> Data Logger page . The value is considered as an absolute value.
The trigger type is selected in the active page Main Menu -> Data Logger.
In case of trigger disable the storage start as soon as you activate the function.
The storage can be MANUAL or at precise time intervals (automatic).
In the case of automatic, a measurement point it is stored to the frequency MAX, set by the parameter acquisition frequency of the
strain gauge channel ranging from 2.5 points per second to 19200 points per second, or at a timed rate that can vary from one point
each 0.1s to 1 point every 30 minutes.
The internal memory of DYNAMIC STAR allows you to store up to 266,000 measurement points if you only use the channel strain
gauge or up to 133,000 measurement points if you also use the encoder channel.
This memory allows, at the maximum storage rate of 19,200 points per second, to store data for up to 13.8 seconds. Using lower
acquisition frequency allows you to increase this time.
Using the trigger (hardware or software) the time interval of interest can be centered optimally.
The table below summarizes better the maximum duration of a cycle of data logger at various frequencies acquisition channel strain
gauge when it is selected as a MAX storage rate.

In case you have not selected MAX but a recording interval from 0.1s to 30 minutes, due to the large internal memory dedicated to
data log, you can create cycles of very long duration.
In this case, particular attention must be paid to supply the instrument that has limited autonomy in about 8 hours.
For very long DATALOG cycles you need to keep powered the instrument through the USB cable connected to a PC or an external
power supply.

DYNAMIC STAR USER GUIDE MO.DYNAMIC STAR.R3.EN
Pag. 14
As an alternative to storage at precise time intervals there is the MANUAL storage.
In the case of MANUAL storage a point is stored with each press of the button.
In this mode and if the PEAK mode is active, it is stored the PEAK value detected instead of the current real time measure.
In this way it is possible to archive all the measurements obtained as a result of a PEAK test.
If you did not select MANUAL mode, in PEAK mode you can not run a cycle DATALOG to prevent from starting a cycle with no
significant recordings.
During a cycle of DATALOG you can not access the Main Menu or turn off the instrument.
If necessary manually stop the DATALOG cycle with the REC button pressed for at least 4.5 seconds.
It is possible to analyze a cycle performed in the Data Log page Menu-> View Log.
On this page you can analyze point by point all the measurements stored.
Alternatively you can use the software WinSTAR (option).
Through this software you can download the whole cycle, display it as a graph, export it to Microsoft Excel, print reports, etc.

24. DISPLAY
This page allows you to set the AUTO POWER OFF time, the deactivation time of the backlight and contrast of the display.
DISPLAY
POWER OFF : 30
RETRO OFF : 15
CONTRAST :18
QUIT
DYNAMIC STAR has got two parameters to save the battery charge.
POWER OFF makes it possible to set a AUTO POWER OFF time from 1 to 99 minutes. DYNAMIC STAR will go off at the set time if no
button is pressed during this period.
RETRO OFF gives the ability to set a time ranging from 1 to 99 minutes to disables the backlight of the LCD display.
In this mode, all functions are active but DYNAMIC STAR consumes less.
It is possible to disable each of these two functions by setting the value to 0.
By changing the value of CONTRAST instead you change the contrast of the display if it is not optimal.
Changing the value automatically changes the contrast so you can immediately assess the effect of the modification.
Modify the value with the keys and . Confirm with Enter for the next parameter.
To quit from the page select QUIT and confirm with ENTER.
25. SET UP STAR
This page allows to modify the communication mode of the USB port and language of the instrument and the enable state for the
encoder channel (only if the option is active).
SET UP STAR
TX MODE : ON DEMAND
LANGUAGE : ENGLISH
ENCODER ENABL. : YES
QUIT
TX Mode : choice field : ON DEMAND –Continuos –Manual
Selecting ON DEMAND to request the current value is necessary to send a command (see chapter on the USB communication
protocol).
In continuous mode instead DYNAMIC STAR continuously transmits (up to 500 values per second in the case where only the
channel strain gauge is enabled or 250 values per second with also the channel encoder) the present value.
The continuous mode of transmission is interrupted by DYNAMIC STAR when any character is received from the USB line.
In this case the instrument automatically activate the communication protocol for ON DEMAND. If for 10 seconds do not come any
data from the line USB tool automatically returns to the continuous mode.
This is useful when, under the control of a program, you want to change some operating parameters of the instrument.
In Manual mode on the main page of DYNAMIC STAR the F2 key: SEND will be enabled. Each time you press the F2 key: SEND the
present value will be sent on the USB line.
The string transmitted in Continuos mode or in Manual mode is the same.

TOTAL TIME: Set the DATALOG duration.
The Datalog cycle will be stopped automatically when the Total time is elapsed or when the internal memory is full (see the
discussion in the dedicated paragraph).
Set the field days (DD) , hours (HH) , Minutes (MM) and seconds (SS) to define the Total Time for the datalog.
TRIGGER : choice field : NO –HW –SW
NO -> Trigger is disabled. The datalog cycle start immediately
HW-> Trigger HW enabled. After you have activated the datalog cycle (key REC pressed for at least 4 seconds) the acquisition start
when the hw trigger is detected. (tansition from high to low of the trigger signal)
SW-> TRIGGER SW enabled. After you have activated the datalog cycle (key REC pressed for at least 4 seconds) the acquisition start
when a load (in absolute value) is detected on the strain gauge channel.
SOGLIA TRIGGER : This parameter is considered only if the SW TRIGGER is enabled.
This value it is in the current unit. No automatic unit conversioni is done changing the measuremt unit of the strain gauge channel.

27. FILTER
This page allows you to change the parameters that condition the digital filter, the acquisition frequency and the resolution for the
strain gauge channel. This parameters influence how DYNAMIC STAR analyzes e shows the measurements.
FILTER
FILTER : 0
ACQ FREQUENCY : 2.5
RESOLUTION : 1
QUIT
In the page FILTER it is possible to set the following parameters:
•FILTER : 0 - 1 -3 -4 - 5
•ACQUISTION FREQUENCY (number of samples for second):
2.5 –5 -10 –16 -20 - 50 –60 - 100 –400 –1200 –2400 –4800 –7200 –14400 - 19200
•RESOLUTION : 1, 2, 5, 10, 20, 50, 100.
This way it is possible to increase the stability of the measurements in dynamic applications at the exspense of the
divisions.
Modify the value with the keys and . Confirm with Enter for the next parameter.
To quit from the page select QUIT and confirm with ENTER.
The parameters FILTER and ACQUISITION FREQUENCY condition both the stability of the measure and the speed with which the
measurement follow the transducer signal.
The RESOLUTION allow to set the minimum increment in the measurement from 1 to 100.
The transducer signal is sampled with a programmable frequency from 2.5 to 19200 samples for second.
In case the encoder is enbaled the maximum acquisition frequency is 7200Hz.
Depending to the set acquisition frequency the accuracy on the sampled signal changes according to the table below.
The divisions are relative to the standard signal of 2mV/V.

The values reported on the table above refere to the single acquisition (FILTER 0). If you apply a digital filter (parameter
FILTER greater than 0) it is possible to obtain better accuracy at the expense of the settling time (see the table below
relative to the answer to a normalized signal step).
After having acquired a value to the set acquisition frequency DYNAMIC STAR applies a digital filter (type moving average). The
number of samples used is determined by the parameter FILTER.
The relation between FILTER and number of samples is descripted in the table below:
