Firmware for the Model MR8847A
The current newest firmware versions are shown below. A version update is highly recommended if you are running older firmware.
・Firmware Version: V2.07
Before you proceed
The version numbers of firmware can be checked by viewing the bottom left portion of the startup window when the MR8847A is turned on.
When selecting "System Information" from "Self check" on System screen, the currently running firmware version numbers will appear at the bottom.
Version Upgrade History
V2.07 (Dec. 2023) Newest Version
1.Fixed a bug where an LVDS lock error would be displayed on the screen and operation would become impossible if a specific value was input to the logic unit when the power was turned on.
2.Fixed a bug where the envelope wave print became faint when performing realtime printing for a long time in a slow range of 10 min/div or more.
V2.06 (Sep. 2023)
1.2A/2V mode is now automatically recognized when a 2A rated current sensor is connected to the U8977.
1.Fixed a bug where some of the odd channels would have incorrect data when performing waveform calculations with either U8975, U8977, or U8978 installed.
V2.05 (Apr. 2023)
・When reading a waveform file that has been measured/saved on a main unit that includes any of the U8975, U8977, or U8978 and other measurement units, the following phenomenon occurs in the data of the latter.
- Waveform values are incorrect when the time axis is displayed compressed to 1/10 or more, or compressed to print at 1/50 or more.
- The recalculated values of numerical calculations (maximum value, minimum value, time to maximum value, time to minimum value, p-p) are incorrect.
- The wrong position is the search result in the trigger search.
V2.04 (Jan. 2023)
・When printing with the level monitor turned on, it freezes about once every 10 times.
V2.03 (Dec. 2022)
・Support GENNECT remote (V2.1.0 or later).
V2.02 (November 2022)
・Fixed the bug that the waveform data becomes wrong value with a probability of 1/8 when the measurement is stopped while the external sampling signal is not input when the roll mode is OFF.
・Fixed the bug that if the AAF setting was ON on the 8968, the value would be incorrect at the first measurement after changing the setting on the "Each Channel" screen.
・Fixed the bug that the data measured at terminals 3 and 4 of the 4CH unit (U8975, U8977, U8978) was not saved in the waveform file in the recorder function.When reading the modified file with V2.00 and V2.01, an incorrect waveform is displayed. Please upgrade to V2.02.
V2.01 (February 2022)
1.Corresponds to the change of parts of this instrument.
*This version upgrade will not affect the performance of your MR8847A.
V2.00 (May 2021)
・U8975/U8977/U8978 units are now applicable.
・When the "Disp Clear" setting is turned off in the XY recorder function, the signal generation control method of the waveform generation unit is set to "Sync.", and measurement is started, the key does not work and the measurement cannot be stopped.
V1.12 (February 2020)
・Communication commands ":MEMory:GETReal, VREAl? and LREAl?" for obtaining instantaneous values can be executed during measurement.
・The CF card reset time has been extended so that it can be correctly recognized even in noisy environments.
V1.11 (November 2019)
・Fixed a bug when AAF is turned on and the sampling speed is set to a speed higher than 1ms/div the accuracy may not be satisfied.
・Fixed a bug that returned to "Measure" when setting the external output terminal to "Waveform","Measure or Waveform" or "Measure and Waveform".
・Other minor bugs were resolved.
・Increased mouse models.
・The setting state of the save channel when saving the waveform file is retained.
V1.10 (August 2019)
・The U8979 charge unit can be used with this model.
・CT6865 has been added to the sensor that can be used in the 8971 current unit.
・The sensor types CT6700, CT6701, CT6710 and CT6711 have been added to the "clamp" of scaling.
・When the measurement is interrupted while waiting for the trigger, the numerical result is also preserved when the waveform data remains.
・Fixed a bug when the measurement of maximum, minimum and peak value is set by numerical calculation, the calculation result displayed when stopping measurement is incorrect may be incorrect.
V1.06 (January 2018)
・Fixed a bug that the value obtained using the communication command ": MEMory: GETReal;: VREAl?" for the 12-bit measurement unit is slightly larger than the correct value.
・Other minor bugs were resolved.
・Variable setting is automatically changed after changing the scaling setting value of the strain unit.
・The automatic balancing method of the strain unit was improved and the accuracy was improved.
V1.05 (August 2016)
・When the auto-saving to PC connected via LAN is stoppded、during measurement by the recorder function or roll mode,Unreadable file is created.
・Not be able to read arbitrary waveform files using the communication command.
・Other minor bugs were resolved.
V1.04 (April 2016)
・While using the remote control function of the 9333,When the LAN cable is disconnected MR8847A to freeze.
V1.03 (January 2016)
・The resolution of the U8974 analog unit is 12bit (but does not affect the accuracy).
・When the destination is a LAN and the image shot is set more than 26div, it fails to create a waveform image save file.
V1.02 (December 2015)
・When the variable is OFF, display value of the variable range of MR8990 is wrong.
・Add a "Generator" tab to CH.SET.
・It supports multiple languages. (English, Chinese, Korean)
