V 2.08 (2023-03-17) Bugfixes: - Corrected: for units without water level sensor, a system crash occurred during discharge measurements unter certain conditions. V 2.07 (2022-11-11) Bugfixes: - Fixed: bug when opening a file in the file explorer menu. (System crash when trying to open a file on the second or higher page in the file explorer). - Fixed: bug related to long file names in real-time mode. V 2.06 (2022-03-09) Bugfixes: - Logfile check during startup revised. (In case of incorrect entries the system got stuck in an endless boot loop). - Fixed: bug when updating entered distance values (discharge measurement). V 2.05 (2021-05-27) Bugfix: Firmware reset after a system crash revised. (Error in connection with "Channel Summary" / "Velocity profile" and low velocity readings.) V 2.04 (2020-10-21) Bugfixes - Fixed: bug with backup files. - Incorrect log entries corrected. - Faulty column labels in the TSV output file corrected (affects measuring point at 70 % of depth). - Faulty timestamp allocation when inserting or removing a new vertical corrected. Firmware optimizations - Added: "Division by 0" test in the measurement summary. - Added: check if an inserted vertical position is before or after the existing position. - Added: automatic y-axis scaling in the measurement summary; this improves readability at low velocities. - Maximum value for manually entered depth values changed to 10.2 meter / 400 inch. - Changed default cursor position when going to previous vertical: the cursor is now on "Back". - Reworked: Romanian language of user interface. - Added: additional maximum value for manual depth input (10.2 meter / 400 inch). New functions - Added: line indicator in the measurement summary to select verticals. - Added: indicator for selected verticals in the measurement summary. V 2.01 ... V 2.03 - OTT internal versions; not published V 2.0 (2018-11-14) Menu structure - Water level and measuring rods - offset can be edited at any measuring perpendicular. - The distance of the current perpendicular position to the cross-section zero point is shown on the display @x.xxx m). - Extended space for name of operator and water body (23 characters). - The name of the water body is automatically suggested as file name when saving. - Dynamic adjustment of the scaling of the graphic for the v-distribution ("Verify" menu). - Marking of the end of the measurement period in real-time mode with a long red line. Measurement - New speed methods added (2-point measurement according to KREPS, 1-point and 2-point ice measurement, 1-point surface measurement, 4-point measurement) - Offset of 2 cm for recommended position of points close to the bottom added to ensure complete flow around the sensor - Output file structure revised (e.g. marking of water level at each perpendicular, recording of measured sensor position, new v-methods added, mean flow velocity in measuring cross section added). General - Number of storable files in real-time mode increased to 50. - Files can be deleted without the sensor being connected to the operator interface. - Measurement data is stored internally. This makes it possible to continue the measurement at the same point after switching the instrument off and on again. V 1.6.0.0 (2016-01-15) - Various graphical optimizations in the handheld's user interface V 1.5.0.0 - Internal OTT version (supports new LCDs; no update required for already delivered units) V 1.4.0.0 (2015-06-08) - Added measurement time for each station in summary report (data post-processing only in QReview versions above 3.00.5) - Added audio beep to signal completion of velocity measurement in FPA mode - Added bottom-up option for calculation of sensor immersion depth - Expanded maximum entered depth for velocity only sensors - Changed minimum required sensor immersion depth for 5- and 6–point–velocity–methods to 4.4 cm (upper measurement point) - Minor bug fixes V 1.3.0.0 (2013-09-11) - Resolution has been changed by default from two to three decimal places. This can be reversed via the menu. - Various bug fixes
