Smart Tweezers ST5S-BT with Bluetooth and Receiver Stick

0Reviews | Write Review


Smart Tweezers ST5S-BT is a Bluetooth enabled version of the ST-5S. This model offers the same features and functionality as the ST-5S with the added ability of remotely recording measurements in real-time.

The ST5S-BT connects using a Bluetooth USB receiver stick (required for use with PC and LabView?.) by opening a virtual serial port allowing users to connect to any communication software such as NI LabView? or free Tera Term software. In the future, there may be dedicated apps for iOS, Android and Windows platforms. The measurement values are sent in a string of comma separated values, ex: C1.398nF,R3.461kR,10kHz,0.5,S,,,,;

The string represents the Smart Tweezers screen at the time of measurement. It is explained as such: C1.398nF (main impedance value, C for Capacitance), R3.461kR (secondary value, R), 10kHz (test frequency), 0.5 (test signal level), S (measurement mode, S for Serial), and 4 reserved values.

The data sent can be saved into a file or documented as required; depending on the program, the data can be processed or saved into a database for later.
