HOBO TidbiT MX Temp 400 (MX2203) and Temp 5000 (MX2204) Logger Manual
| Logger | |
| Full Memory Download Time | Approximately 45 seconds; may take longer the farther the device is from the logger |
| Logger Battery Life | 3 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off disabled in software. 5 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off or Bluetooth Off Water Detect enabled in software. Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life. To ensure proper battery installation, see Battery Information for detailed instructions on replacing the battery in the MX2203 logger. |
