Version Upgrade History

V1.10  (February 2022)
Added functions
・Tests discharge status by performing impulse testing in which the applied voltages comply with the IEC 61934 procedure.
    This function only for models equipped with ST9000 Discharge Detection Upgrade.
・Applies voltage pulses continuously.
・Measures rise time.
・Selects the method used to position the master waveform and measured waveforms.
・Flexible configuration of automatically setting the waveform judgment scope and threshold values.
Bug correction
・ESR0 may not reflect the status of the second and subsquent measurements when measures many times without reading ESR0.
・If LC or RC judgment measure value becomes negative at voltage calibration, the LC/RC points are outside the display range of the graph.
・Minor additions and corrections.
Postscript (28 Jul 22)
・Updated software upgrade manual.

V1.05  (September 2021)
・Fixed a bug that when turn on the power in the key lock state, the EXT.I/O START signal does not work until the settings are changed.
・Fixed a bug that when turn on the power in the key lock state, the output voltage becomes about 1% to 7% smaller until the settings are changed.

V1.04  (December 2019)
・Unified the firmware for the ST4030 and ST4030A.
・When the settings saved in ST4030A are loaded into the ST4030, only settings that can be output by the ST4030 are read.
・Fixed minor bugs.

V1.02 (September 2019)
・Increased the number of response waveforms that can be evaluated.
・Improved usability with respect to creating threshold values.
・Fixed minor bugs.
