1. The detector stores the last 30 event logs. If the data is filled, the new log event 

overwrites the oldest log events. 

2. The data log is stored at every 1minute interval, and it stores about 64,000 data logs. 
3. Data logs consisting of event log, bump, calibration are stored at 1minute interval. 
4. To transfer event logs and data log to a computer, follow below steps.  

- Install the recent iGas detector USB link software. 
- Connect the detector with a computer via a USB-C cable.
