1 flash/second
Logger successfully deployed and
logger is healthy.
2 flashes/second
Logger successfully deployed but
Logger battery has less than 10%
capacity remaining.
3 flashes/second
Logger successfully deployed but
Logger memory has less than
10% capacity remaining.

Battery in
QuickDeploy
™
Key is
dead. Replace the battery.
This information is also printed on the
QuickDeploy™ Key.
It is inadvisable to proceed with deployment if the
Logger battery or memory is low, as indicated by
multiple LED flashes. This could result in data loss.
If you receive a single flash once per second, this
indicates the Logger has been successfully
deployed, has logged its first data point and can
now be attached to its suspension cable and
lowered into position.
Simply unplug the QuickDeploy™ Key and proceed with your installation. Do not leave the
Key plugged in any longer than necessary as this will quickly deplete the Key's battery.
3.4.3. Using the QuickDeploy™ Key After Deployment
As well as initiating logging, the QuickDeploy™Key also embeds a zero marker in the
logged data. The data associated with this zero marker can be used in the LeveLink
™
software as a barometric pressure reference during data correction for atmospheric
pressure. See section
At any time during the Logger's deployment, a QuickDeploy™ Key can be re-connected to
the Logger to check battery and memory status and to embed further zero markers. This is
particularly useful if you are not simultaneously logging barometric pressure at the same
site but want to keep track of the barometric pressure on say, a daily basis.
3.4.4. QuickDeploy™ Key Battery Replacement
The QuickDeploy™ Key contains an integral 12V alkaline battery (type 23A, MN21, MS21,
A23 or VA23GA). If the LED on the QuickDeploy™ Key fails to flash when plugged into a
Logger, replace the battery. This is accessed by unscrewing the blue plastic housing from
the metal body of the Key and is self explanatory.
3.5. Deploying the LeveLine
®
Mini and Mini-CTD
The advice for deploying the Mini versions is largely the same as that for deploying the full
size versions. Please refer to the previous section for more details.
Because the Mini Probes are designed solely for use with remote logging or telemetry
systems, they must always be deployed with a power/communication cable. When
deploying a Mini Gauge version, a vented cable must be used.
