  • Page 27 3. MEG APPLICATION SOFTWARE The MEG application software is used to: ■ configure the instrument and the measurements, ■ transfer the data recorded in the instrument to a PC. MEG can also be used to export the configuration to a file and to import a configuration file. Your PC must be equipped with a Bluetooth adapter (V2.0 or higher, supporting the SPP profile).
  • Page 28 Then, in the Windows bar, locate the Bluetooth logo , right-click on it, and choose Add a peripheral. The PC searches its environment for Bluetooth-compatible devices. When the megohmmeter is detected, select it and click Next. If a coupling code is requested, enter 1111.
  • Page 29 You can then transfer recorded data from the instrument to the computer. If you turn the switch to an insulation position, you can transmit the measurements in real time. To use the MEG software, refer to its help function. Each time the connection with the MEG software is lost, Bluetooth is deactivated on the instrument. Press and hold the key to reactivate it.
