Version Upgrade History

V2.02 (August 2021)
1. Fixed bugs
-1. Fixed a bug that a response is returned when a ping command is sent to the old IP address after changing the IP address.

V2.01 (October 2019)
1. Fixed bugs
-1. Fixed a bug where the zero adjustment would not end when performing a zero adjustment while displaying certain screens.
2. Enhancements
-1. Changed the calculation method of the integrated power SUM value in multi-phase wirings in order to match to integration in buying and selling power. Power analyzer splits WP to WP+ and WP- according to the sign of the instantaneous SUM value.
-2. Other minor improvements were made.

V2.00 (May 2018)
1. Added functions
-1. Added a trend screen.
-2. Added a load function for screen shots.
-3. Added a FFT spectrum save function for noise measurements.
-4. Improved the following performance attributes for the noise analysis function:
Increased the maximum noise analysis frequency to 200kHz.
Decreased the minimum noise level from the current specifications by 20dB.
Improved calculation precision.
-5. Added the ability to manually adjust the motor phase zero adjustment value.
2.Fixed bugs
-1. When automatic save is turned OFF and waveforms are being saved while integration is being performed at an interval of 5s or shorter, missing points in the integration was found to occur. Also, regardless of the state of automatic save, if there are attempts to download waveforms using the PC application while integration is being performed at an interval of 5s or shorter, missing points across the entire measurement data file was found.  This phenomenon has been fixed.
-2. Other minor bugs fixed.
3. Enhancements
-1. Replaced the text [deg.] with the symbol [°].
-2. Added support to events of synchronized measurements for the :HOLD and *TRG commands for the hold function via PC communication.
-3. Changed factory default settings for noise analysis related settings.

V1.01 (June 2017)
