53Measurement Menu6.3 Measured data storageThere is one measurement file which contains the data generated by the measurement cycle.The measurement file is updated in volatile memory, and regularly copied in non-volatilememory (file back-up). At start up, the measurement file in volatile memory is updated with thefile from the non-volatile memory.This dialog box allows adjustment of the parameters forrecording and storing measurements.• Storage mode selection:• No storage• Store once: When the volatile memory is full (1,000positions), the recording of measurement stops.• Rolling buffer: When the volatile memory is full, thelatest measurement set replaces the oldest onecontinuously (first-in, first-out)Note: Data stored in volatilememory are lost when instrumentis off, non-volatile memory ispermanent. In case of anaccidental power off event, theinstrument resumesmeasurement storage after thelast measurement stored in flash.• RAM time (volatile memory): Delay in seconds betweentwo recordings of measured data.• FLASH time (non-volatile memory): Delay in secondsbetween two data file transfers from volatile memory intonon-volatile memory. The last data file erases the previousone. This field is only available if the Auto save in flash boxis checked.• Save in flash now: Press this button to store measurementdata in flash (non-volatile memory) immediately. Afterpressing this button, press OK to initiate the process. Awarning screen appears informing you that the operationcan take up to 30 seconds. Press Yes to continue with theprocess, or No to abort.• Auto save in flash: Check this box to save measurementsin flash (non-volatile memory) automatically.Measurements are saved at regular time intervals asdefined in the FLASH time box.• Purge data: Clear all data in the volatile and non-volatilememories• Start logging measurement: Store once mode. Starts andstops the measurement recording session. Measurementrecording is stopped when the buffer is full.• Open data: Opens a table showing the measured valueswhich are stored in the volatile memory (RAM).Use the scroll bar at the right to move to another datarange (the id range will be shown in the title bar).The page number being viewed and the total number ofpages are shown at the bottom (page 1 of 13 in theexample left).Use the keys at the bottom to move directly to the firstpage, previous page, next page or last page.
