To shorten a ShapeArray (SAA) it must be sent back to Measurand. Due to the waterproofing systems it is not possible to shorten a ShapeArray outside of Measurand.

If a shorter ShapeArray is needed, consider instead using the ‘Turn off/Ignore Segments’ option available in 'SAA Setup \ Advanced \ Turn on / off section of SAA' section of the SAARecorder manual or the 'Selecting Settings' section of the SAACR_raw2data manual.
