T&M Data Collector

● Features

• Bluetooth-Enabled Digital Measurement Measurement data from Yokogawa’s Leakage Clamp-on Tester 30032B and 30042B can be wirelessly transferred to smartphones and tablet PCs via Bluetooth. This eliminates manual transcription errors and significantly improves the efficiency and overall quality of inspection work. The collected data can be handled as digital information—easily sent by e-mail or saved as CSV files—enabling efficient data analysis, post-processing, and centralized data management.

● Functions

• Flexible Data Logging Measurement data can be captured either continuously (logging mode) or manually one reading at a time. Logged data is stored directly on the mobile device and displayed together with the exact time of acquisition. Upper and lower limit values can be preset in advance, allowing automatic pass/fail judgment to be performed simultaneously during data logging. This enables quick identification of abnormal measurement results.

• Graphical Data Visualization Logged data can be displayed as a trend graph or histogram, allowing users to visually confirm variations and tendencies in measurement values. Trend graphs are especially useful for identifying intermittent leakage currents, as they allow users to observe the timing and pattern of sudden leakage events.

• CSV File Export and Data Management Logged measurement data can be saved as CSV files on the mobile device. These files can be sent directly by email, making it easy to archive inspection records and perform further data analysis. Previously stored CSV files—such as those saved on servers or other storage systems—can also be imported and reviewed on the mobile device.
