Version Upgrade History

V1.05 (December 2017) Newest Version
Improved Functions:
1.The automatic changing range with the average function enabled is improved, resulting in the other improvement such that the most appropriate measurement range is settled even if the ranges are changed several times.
2.The firmware has been improved so that when checking the cable length during OPEN compensation and the actual length is not consistent with the specified length, you can verify this on the screen even during compensation.

V1.04 (January 2017)
 Fixed bugs:
・In continuous mode, sending one of the following commands immediately after the instrument acknowledged the EOM signal caused an execution error.
:MEASure?, :MEMory?, :MEASure:CONTinuous:COMParator?
・During USB communications with a computer running Window 8, Window 8.1, or Windows 10, the instrument sent back two responses.
・Restarting the instrument after deleting a panel, which contains measurement condition data and correction data, may have disabled any more panels to be saved.

V1.03 (April 2016)
Fixed bugs:
While setting to Internal trigger and measuring continuously, send a query command continuously by GP-IB I/F, measuring rarely stops.

V1.02 (January 2015)
Fixed bugs:
1.When [ADJ]panel was loaded, the compensation could not be done correctly.
When a saved panel consisting of only compensation values was loaded, the panel seemed to be loaded on the screen; however, measured values were not compensated, if one of the following statuses of the loaded panel was different from one of those currently set in the instrument:
- Open compensation (OFF, SPOT including measurement frequency, or ALL)
- Short compensation (OFF, SPOT including measurement frequency, or ALL)
- Load compensation

2.Measurement status of ε or σ did not indicate ”DISP OUT”.
If the error message, ”DISP OUT” was displayed for a measured value of ε or σ on the screen, the response message for the measurement status query sent via communication was not ”3”, which represents that a measured value is out of the display range.

V1.01 (November 2014)
