You can calibrate your meter using an acoustic calibrator like the CAL150 or CAL250. Fit the calibrator securely over the microphone, turn it on to generate a reference signal, and enter the corrected expected level into your measurement system.
The G4 LD Utility software can typically be found on the USB drive included with your device or downloaded directly from the Larson Davis support website.
You can connect via Bluetooth using the LD Atlas App, which is available for both iOS and Android. Ensure your dosimeter's Bluetooth is enabled and pair it within the app's 'Manage Meters' menu.
