3.5 Запись и экспорт данных
The MS-4000 can record up to 100,000 points of offline data. This data can be easily exported to a computer via a USB port for further analysis of temperature, pressure, and vacuum values.
3.6 Auto Off Time Settings
The device has an adjustable auto-off feature to conserve battery life. Default auto-off is set to 15 minutes, but options like 5, 10, 15, 30, and 60 minutes are selectable.
4. Техническое обслуживание
4.1 Общий уход
Keep the manifold gauge clean and free from dust and debris. Store it in its protective carrying case when not in use to prevent damage. Avoid exposing the device to extreme temperatures or moisture.
4.2 Управление аккумулятором
For long-term storage, it is recommended to fully charge the device and then store it in a cool, dry place. If the device uses removable batteries (like 3 AA batteries in some models), remove them if the unit will not be used for an extended period to prevent leakage.
