Manufacter: AEP transducers s.r.l Address: Via Bottego 33/A 41126 Cognento MODENA (Italia) DECLARES THAT THE FOLLOWING PRODUCT Product Name: DYNAMIC STAR Type: FAST ACQUISITION PROFESSIONAL HANDHELD INDICATOR Year of Construction: 2015 Options: this declaration covers all the options specified in the manual. - Page 4 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.

DYNAMIC STAR and support the user in the various functions of calibration, testing, analysis, data storage, transfer of measures on Microsoft Excel etc..WINSTAR is a software dedicated to DYNAMIC STAR. Through this software you can download the data logger and operate directly on DYNAMIC STAR to change parameters and create graphics test. -
Page 9: Maintenance
To avoid that there may be inadvertent shutdowns of the instrument during a Data Logger cycle the button is disabled when a datalog is active. Therefore in case should be necessary to turn off DYNAMIC STAR during a data logger cycle you must first stop the Data Logger (hold REC button for 4 seconds). -
Page 10: Power Measurement
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. - Page 11 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.

LOW BATTERY 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. -
Page 13: Peak Function
MO.DYNAMIC STAR.R3.EN 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+ PEAK- on the display shows which PEAK is active. -

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. - Page 15 DYNAMIC STAR USER GUIDE MO.DYNAMIC STAR.R3.EN 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.
- Page 16 The value fields are parameters where you have to enter the value using the keys and that allow to increase/decrease the value. The choice field are parameters where the valid values are proposed directly by DYNAMIC STAR. Scroll the proposed values with and until you find the desired value.

(2) mV/V uniti is useful to check the transducer output in a not engineering unit to verify the real electric signal in input (3) The selection of the unit select if DYNAMIC STAR will compute a position value o a speed value. - Page 18 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.

Note : It is necessary to power supply the encoder from an external +5Vdc power supply. DYNAMIC STAR has an 5Vdc output but it is rated just for 10mA. Normally this current it is not enough for optical incremental encoder.
