Bug Fixes

• Using RUN/STOP in conjunction with a Timed, Level-Triggered run would generate a card error.  The session would not be properly saved due to the card error.  Furthermore, all subsequent file access would continue to generate card errors until the unit was turned off and then back on.  The problem was corrected.
• When filter band SPL values are significantly below the bottom of the range, large Lavg values could be reported due to a discrepency between the measurement floors between the SPL and Lavg calculations. The code was modified to dynamically limit lower SPL values to the Lavg measurement floor.

Bug Fixes

• Using ill-conditioned NiMH batteries can cause the session to not get completely saved on low-battery shutdown.  The low-batt thresholds were adjusted to correct the problem.
• The firmware was changed so that a run will not commence with a full card.  If the operator wishes to run without saving, he/she will need to pop the card before starting the run.
• Occasionally a session would be lost and only a zero-byte file would remain.  This has been corrected.

Bug Fixes

• Occasionally the contents of a data file would be lost when the user performed lots of quick successive sessions. This has been corrected.
• UTC time received from the GPS was not correctly being populated to the session file. This has been corrected.
• After exiting file review the meter would be in the same mode as the previously viewed file, not the mode it was in before the file was loaded for review.  This has been corrected.
• When reviewing STI-PA files after exiting file review the STI-PA settings would be left in the same state as the previously viewed file, not their state prior to loading the file.  This has been corrected.

New Features

Triggering

• Windowed Trigger
  The operator can now select an upper and lower level or curve and trigger when the current measurements go outside the defined bounds.
  
  
• Delay Trigger
  The operator can now specify a run start delay.  When enabled, the unit will wait a specified amount of time from the moment the run button is pressed before the run actually begins recording.  This is useful for certain types of room testing where the person evaluating the room needs time to exit the room as to not influence the results.
  
  
• Triggering from Meter 2
  It is now possible to use Meter 2 as a broadband meter source.  Previously the instrument could only trigger off of meter 1.
  
  
• Separate ON/OFF Sources
  Previously, the ON and OFF levels used for triggering always applied the same filter band or broadband meter.  Now the instrument allows the operator to select the source for the ON and OFF levels independently.  For example, this allows the operator to trigger the start of a run when a curve is exceeded and trigger a pause when the broadband value falls below a specified amount.
  
• Updated User-Interface
  The triggering menus were redesigned and condensed from three menu selections into one menu selection.  The start and stop of triggered runs is now available on one menu only which is the “AutoRun” menu with Level-Triggered enabled.
  
  
• No AUTO-RUN Power down Requirement
  In the past, in order to run a study under auto-run mode, you had to power-down your meter.  With the new change, the operator no longer needs to power down the unit for AUTO-RUN Date and Day-of-Week alarms to work.

Upgrade/Update

• Field-Upgradable Options
  The instrument now supports the ability to load options from the SD card.  This allows Quest to sell option upgrades after the initial sale without requiring the customer to return the unit.  The updates are tied to the unit serial number and use 128-bit key encryption.
  
  
• New Update Commands
  Once this firmware is installed in the unit, it will be able to be updated via the normal QSP communications interface instead of requiring the use special key sequences during boot (bootstrap mode).  This also alleviates the issues with the XP PNP manager misidentifying the TI bootstrap mode and locking up the unit the very first time it is plugged in.

Measurements

• Study-based Statistics
  The instrument now saves the statistics table in such a way that study-based statistics and exceedence tables can be generated.  Previously these were only available on a per-session basis.  The instrument itself still displays only session-based stats.  The incremental stats are intended to be used by QSP-II.
  
  
• Study-based CNEL, LDN, Lc-a and Taktmaximal
  The instrument now saves these measurements in such a way that they can be displayed on a per-study basis by QSP-II. 

File System

• Updated File Format
  The new file format vastly reduces the likelihood of file corruption in the event of problems with SD card. The updated format also allows the instrument to detect and ride through file corruption, whereas previous revisions would likely lockup or worse, further corrupt the card.  It also reduces the size of a session file in the typical use case.

Miscellaneous

• Removal of DEMO Mode
  Upon loading this firmware revision, units previously sold as discounted demo units will no longer display the DEMO splash-screen at startup and will function in every way as a non-DEMO SoundPro SLM.
  
  
• How the meter saves settings
  The instrument now has the ability to incrementally initialize saved settings based on the loaded firmware revision without performing a complete system default.
  
  
• Battery Life
  Battery Life has been increased by approximately an hour of typical use over the previous release in the filter modes.

Bug Fixes

Triggering Updates

• The date alarm indicators were not updating immediately when individual alarms were enabled or disabled. This has been corrected.
• If day of the week alarm was set (+1), it was not updating when you disabled the alarm. This has been corrected.
• Updates were made to correct issues with level-triggering during AUTO-RUN Date or Date of the Week mode.
• When level-triggering settings were enabled, the external trigger setting was not detected (ignored this setting). This has been corrected.
• When triggering was enabled and multiple timed runs were stored, there was a file error. This has been corrected.
• When Date of the week mode was set for Auto-runs settings, sometimes the triggering did not start because of the time and length. This has been corrected.

User Interface and Measurements

• Frequency Weighting was dropped from session path. This has been corrected.
• The meter locked-up when viewing current study before a user’s first run and after it loaded config files. This has been corrected.
• Updated the battery check display screen which had an inconsistent title.
• Corrected a file error issue when the run time of previous study was displayed in stopped mode.
• Backlight turns off when reloading files or when exiting file review. This has been corrected.
• Occasionally, the unit spontaneously goes back to main menu. This has been corrected.
• Exceedence measurements tended to be skewed by a data-dependent amount. This has been corrected.
• Exceedence measurements could exceed Lmax for short runs. This has been corrected.
• Instrument would occasionally lockup when sending or retrieving setups from instrument into QSP-II. This has been corrected.

Language settings

• Various language settings and displays were updated as needed.

USB and Command Parser

• There were communication problems if the USB cable was pulled out mid-command. This has been corrected.
• Command responses can get out of sync with original commands. This has been corrected.

GPS

• Updated time settings and made changes to the Setup/Comm-set screen to show GPS data.

File Review and File System

• There were some incidents where a low-battery drop out would result in lost data. This has been corrected.

Instrument Display Related

• Added additional translations into instrument’s display/menus.
• The graph of Leq and Lavg were corrected when 1/1 was enabled and if thresholds were enabled.  (It was calculating incorrectly.)

Serial Command Related

• LN command now defaults to LN1 if the exceedance level number is not included.
• Exchange rate (ER) now defaults to meter 1 if the meter number is not included.

File System Related

• Sending instrument setups from QSPII was causing excessive memory card fragmentation which was corrected.
• File directory information sent from the meter to QSPII was incorrect if there were more than 15 files on the card which would lead to a download error which was corrected.
• Per customer request, formatting the card will now reset the session counter back to “1”.
• Corrected an error in how time stamps from QSPII are handled.
• Updated error checking in configuration files from QSPII.

Real Time Clock Related

• Real time clock failed to reset or start if backup battery power was lost.  Now, it will clock time when a new battery is inserted.

Triggering Related

• When using logic trigger 1, meter did not activate properly which was corrected.

Power Down Related

• Occasionally when the instrument was turned off, it would lock up at the end of its count down sequence.  This was due to invalid setup information from QSPII.  It has been corrected.

All issues listed below have been corrected in this release.

Instrument Display Related

• When recalling logged sessions and viewing the 1/1 and 1/3 displays, the graph range and the numeric range did not match.
• When setting up a personal microphone (not supplied by Quest Technologies), if you changed the current meter range (ie, 150db) the Range CAP would not match to the Range of the Microphone.
• If you pressed the back-erase button at 1 second intervals for the entire run, it would restore the entire file instead of erasing it.
• The back-erase feature would corrupt the Stat table when viewing measurements. 
• The back-erase feature corrupted the session file if applied up to the last second of the level-triggered.
• On single octave display, meter 2 was updating at a slower rate than meter 1 for the Lavg/Leq.
• If conducting short run trigger sessions, it would lock up.
• If in setup mode, the level font size would change.
• Portuguese language was turned to English.  This has been changed to Portuguese.
• The abbreviated days of the week were only translated in English.  These have been changed to their respective language.
• In the Time/Date screen, the word “Day” was not translated into its respective language.  This has been modified to reflect the appropriate language (i.e., Day in French is La Jour)
• When viewing timed-run parameters in the pause mode, it displayed incorrect data. 

Logging and Measurement Related

• If level trigger run was on, the data was fixed to record the graphs but it would occasionally skew the data. 
• If you used higher range microphones, the 1/3 and 1/1 octaves displayed an inaccurate RTA measurement if the range was greater than 140db. This was corrected.
• The logged data value for Lavg did not calculate accurately in QuestSuite Pro software for Meter 2 only. 

Triggering Related

• While running many triggered runs, it did not display the results properly and thus, would shutdown QuestSuite Pro software.
• If level-trigger was set to 1/1 or 1/3 octave, it would not allow you to set the trigger mode. 
• If you were setting up the auto-run feature to the date of the week, the cursor  would disappear as you moved through the week days.
• If you set auto-run to a certain day of the week and then you looked through the auto run menus, the session would not stop. 
• In AutoRun mode, the cursor disappears in the date field if the alarm is set to off.
• If you were running a 24 hour test and then you paused and wanted to run another test, the instrument would not start or stop. This has been corrected.
• If you were conducting short level runs, it would lock up the instrument. This has been corrected.
• In Autorun, you can set the time normalized feature to end at a particular day/date.  This feature did not work properly if it was set for over 2 months.  This has been corrected.
• In the Trigger mode, if the time run was set for hours/minutes/or seconds it would not correspond accurately. This has been repaired.
• In the Trigger mode, if you turned on the trigger run and the auto-run feature, it would log the first test appropriately but not with a combination test.  It would not start the second test.

Real Time Clock Related

• Repaired the corrupted time in the Autorun mode.

GPS Setting Related

• GPS setting was repaired to reveal the appropriate elevation. 
• GPS feature was repaired to update the location reading to the instrument every  15-30 seconds.
