The ST5S-BT2 model is able to receive data also, including specific measurement settings set by custom profiles.

computer accepting data from Smart TweezersST5S-BT2 connects to a device using a USB receiver stick that establishes a virtual serial port. (Note: The receiver stick must be used with PC and NI LabView software). The measurement values are sent in a comma separated string of values that represent what is present on the device's screen.
An example of this string: C1.398nF,R3.461kR,10kHz,0.5,S,,,,;
The string is explained as such: main impedance value type, C, and its value, 1.398nF, secondary impedance, R, and its value, the test frequency 10 kHz, test signal level 0.5 V, the measurement mode S for Serial, and 4 reserved values.

This information is sent and can be saved into a file or document as required. When using LabView software, the computer could process the data for future use or store it in a database.
