Page 23: Leveline® Scheduled Logging Start, Logging Interval And Duration Setup
Unless you are monitoring live pumping operations or similar dynamic events, water levels, EC and barometric pressures tend to alter reasonably slowly. For this reason, logging rates between 1 and 15 minutes, and barometric pressure logging rates between 15 minutes and 1 hour are normally recommended. © 2019 Aquaread ® Ltd. www.aquaread.com... - Page 24 Finally, once the scheduled logging start, logging interval and duration (if required) have been set up, transfer the settings to the Logger by clicking the 'Update Logging' button. © 2019 Aquaread ® Ltd.
