Smart Tweezers with Bluetooth Records Measurement Results As They Happen

Smart Tweezers with Bluetooth Connection

The new Smart Tweezers ST5S-BT2 combines the same features and functions found on Smart Tweezers ST-5S with the added benefit of real-time measurement documentation. The device can send data to and receive data from communication software for computer, Android or iOS, and can be recieved using programs such as Native Instruments LabView® and free software such as Windows' Smart Tweezers Bluetooth Utility , as well as dedicated apps for iOS and Android.

Tera Term accepting dataWhen ST5S-BT2 is connected, the USB receiver stick will open a virtual serial port to send the data. The device sends all data that is on the display at the time of measurement in a comma separated string of values.
EX: C1.398nF,R3.461kR,10kHz,0.5,S,,,,;
This is explained as follows: main impedance type and value, secondary value and type, test frequency, test signal level, measurement mode and 4 reserved values.

Depending on the software used to receive the data, it can be saved in a file or folder, or into a database for processing later.

To connect with computers, the USB receiver stick must be used, especially when using NI LabView®. Android and iOS have dedicated apps for mobile devices.

The ST5S-BT2 offers users the same features and functions found on the ST-5S model. The device is still able to instantly recognize the type of component and best test parameters to use when the gold-plated tweezers have made contact. All measurement results are instantly displayed on the OLED screen in the device.

Using Communication Software with Smart Tweezers ST5S-BT2

Note: The Bluetooth receiver stick must be used for connections to certain programs ie: NI LabView®.

Microsoft Window's Smart Tweezers Bluetooth Utility

ST5S-BT2 can connect with Windows 7, 8 or 10 using the Smart Tweezers Bluetooth Companion and receiver stick. This program allows users to send and receive data from the device. The device will send the measurement results to the program. Custom profiles can be set using previous measurements or from scratch; these profiles can also include specific parameters, such as test frequencies, that can automatically be set on the device over the connection.
When test results have been received while using a profile, the program will automatically grade the results as a pass or fail, marking the result as red or green. This feature is ultimately helpful when fast, but accurate, measurements are required.
Data received by the program can either be exported as an Excel-compatible file, or copied and pasted into a preferred file type.
Siborg has created a manual for use with Windows Smart Tweezers Bluetooth Companion.

Using National Instruments LabView ®

National Instruments LabView
National Instruments' has certified and supports the driver for use with ST5S-BT2. This allows the device to seamlessly integrate into the programs environment. LabView® is able to log measurement data for later processing or saving into databases.

Dedicated Apps for Mobile Devices

The Bluetooth enabled device can connect to Android and iOS smart phones and tablets using available apps.

Custom Applications

The device can also connect to custom made programs using the receiver stick's FTDI bridge. This creates a virtual RS232 serial port allowing for the connection.
