Smart Tweezers ST5S-BT with Bluetooth and Receiver Stick

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.
