IT-19C changes log

v1.2.7.0 of 28.07.2020
Build number: 200728

  • Fixed an error in measuring battery voltage that could lead to premature shutdown of the device;
  • "Scan". Reduced time for determining the type of channels when working without a channel plan;
  • Other non-critical bugs fixed.

 

v1.2.6.0 of 22.06.2020
Build number: 200622

  • Redesigned the signal-to-noise ratio measurement algorithm. In particular, the method of measurement in channels with audio modulation A2, STEREO, DUAL, NICAM in loaded channel plans has been improved;
  • Fixed an error that led to incorrect battery charging indication on some devices;
  • "Channel test". Added the ability to change the direction of sorting files when you select the same type of sorting again;
  • "Channel test". Sorting type is saved to non-volatile memory.

 

v1.2.5.0 of 08.11.2019
Build number: 191108

  • Added German language;
  • Improved reference level detection algorithm;
  • Other non-critical bugs fixed.

 

v1.2.4.0 of 13.08.2019
Build number: 190813

  • If analog channel had a certain audio modulation (NICAM etc.) the signal-to-noise ratio  measurement was incorrect.

 

v1.2.3.0 of 08.08.2019
Build number: 190808

  • Reworked automatic reference level detection algorithm;
  • Other non-critical bugs fixed.

 

v1.2.2.0 of 03.07.2019
Build number: 190703

  • If the device was switched off during measurements certain settings (averaging, level scale etc.) had not been saved to the nonvolatile memory;
  • "Computer" mode will be entered if USB is plugged in before switching-on;
  • Other non-critical bugs fixed

 

v1.2.1.0 of 25.06.2019
Build number: 190625

  • "Channel test". Critical bug occured if the amount of channel test files was at the maximum (250 files);
  • Increased performance of signal-to-noise ratio measurement for analog channels;
  • Other non-critical bugs fixed

 

v1.2.0.0 of 19.06.2019
Build number: 190619

  • Reworked signal-to-noise ratio measurement for analog channels. For those clients who bought the device with earlier firmware the recalibration have to be performed;
  • Other non-critical bugs fixed.


v1.1.0.0 of 30.04.2019
Build number: 190430

  • Reworked signal-to-noise ratio measurement for analog channels. For those clients who bought the device with earlier firmware the recalibration have to be performed;
  • Improved performance of files data exchange between ViewIt19C and the device;
  • Added channel type indicator in measuring modes. Lock indicator was moved to system panel;
  • Added factory reset button in the "Self test" mode;
  • Added sound indication after last channel measurements end in the "Channel test" mode;
  •  Other non-critical bugs fixed.


v1.0.2.0 of 02.04.2019
Build number: 190402

  • Initial revision.
