If you have read and understand the information above and wish to proceed then please download the designated files.
As for version upgrade procedure, please download ”Procedure on how to update the firmware” which describes the preparation and procedure for upgrading firmware after downloading the files.

Precaution when updating firmware:
・To conduct the version upgrade, USB memory stick is required.
・You need to install USB driver in advance. Please refer to the instruction manual available as an HTML file on the Application Disk for how to install USB driver.
・When the firmware is upgraded, all the settings will be reset to the factory default.
・During the version upgrade process, don't turn off the power to the IM3523 or don't remove the USB cable from the connector.

If version upgrade is conducted with a computer running Window 8, Window 8.1, or Windows 10 , please conduct it in the following condition with the instrument and a computer connected with each other with the USB cable.
・Turning on the instrument, and then turning on the computer.

Version Upgrade History

V1.13 (August 2020) Newest Version
Improved Functions:
1. Added :TRIGger:DELAy and :TRIGger:DELAy? commands compatible with the 3532-50.
2. Modified the small bug.

V1.12 (April 2020)
Improved Functions:
1. Added support for the use of the control characters LF as a command terminator.

V1.11 (November 2018)
Fixed bugs
・Fixed an issue that may freeze when measuring with auto range setting in analyzer mode of IM3533 - 01.

(January 2017)
 Fixed bugs
・During USB communications with a computer running Window 8, Window 8.1, or Windows 10, the instrument sent back two responses.

V1.09 (April 2016)
1. Fixed bug
While setting to Internal trigger and measuring continuously, send a query command continuously by GP-IB I/F, measuring rarely stops.

V1.08 (July 2015)
1. Fixed bug
No AC measurement signals were output while AC measurement and DC resistance measurement are performed simultaneously.

V1.07 (January 2015)
1. Fixed the measurement value to positive value which occurred when DC resistance measurement is performed by OPEN correction value by high resister or SHORT correction value by low resister.

V1.06 (August 2013)
1.Fixed a bug that sometimes the instrument get hung up when using the LAN interface.
2.Fixed a bug that the instrument can’t accept the connection when the instrument is disconnected during communication of LAN.

V1.03 (July 2012)
1.Fixed a bug that it may not detect contact error in contact check function.

V1.02 (June 2012)
Added functions:
1.3522-50 compatible communication commands are now available.
 [MODEL:IM3523, IM3533, IM3533-01]
Repaired bugs:
1.[All load] function was performed for the file data, the panel information could not be loaded correctly (When [Analyzer mode] or [ADJ setting] was saved to panel).
 [MODEL:IM3533, IM3533-01]
2.When [Trigger] function was set to External and [Trigger synchronous output] function was set to ON, if the DC bias level was changed, DC signals were output as measurement signals. (No problem about AC signals)
 [MODEL:IM3523, IM3533, IM3533-01]
3.When [DC bias] setting was OFF in Analyzer mode, a DC bias value could be set by using communication commands even if the DC bias value should not be set due to the restriction caused by the sum of the DC bias value and the level value.

V1.01 (May 2012)
1.Change FPGA program.

V1.00 (March 2012)
