3.4.4 MEMORY OPTIONS (ERASE TESTS)
Click the Memory Options (Erase Tests) button (Figure 3.29) to open the ‘Change Memory Options’ window (Figure 3.30). This
window displays how much free memory is available. This window also allows you to select between ‘Wrap’ or ‘No Wrap’ memory
options:
ƒ No Wrap –When memory is used up, the Level Scout stops measuring and logging data. Any active test will turn off.
ƒ Wrap – When memory is used up, the Level Scout begins to write the newest data over the oldest data.
The Level Scout can store up to 288,288 pressure scans if using the low memory Level Scout or up to 393,120 pressure scans if using
the high memory Level Scout. Checking Clear Memory (Erase All Tests) and pressing OK will delete all stored data and clear all 16 test
configurations.
The Level Scout can store up to16 discrete test configurations. You may ‘vacate’ a test configuration from the Test tab to clear the
configuration in order to set up a new test configuration. Vacating a test configuration does not delete that test’s data from the
transducer’s memory.
Important: If there is any relevant data stored within the transducer, it should be extracted prior to performing a Clear Memory
operation. Erasure is permanent once it has been initiated.

3.4.5 CHANGE TRANSDUCER ADDRESS
Click the Change Address button (Figure 3.31) to enter the ‘Change Address’ window (Figure 3.32). This function changes the Level’s
Scouts SDI-12 address. Addresses can be single characters within the range of 0-9, a-z, and A- Z. After selecting a new address, click OK
to save. Data Scout will automatically change its configuration to maintain connectivity.
The Level Scout transducers are addressable, and if there are more than one transducer attached to a single serial port, then unique
addresses are required in order to communicate to all of the transducers. This requirement is especially important when multiple
transducers are to be attached to an SDI-12 data logger.
