Hello, we are currently trying to learn about the update process of the ET44XX and ET45XX lcr-meters.
https://www.eevblog.com/forum/testgear/east-tester-et4410-desktop-lcr-meter/msg5542409/#msg5542409

I would like to do some comparisons with the ET54XX electronic load. Did anyone download that update files and could share them?

The user never posted or sent the files to me, so can't help you. One thing I advise all owners of these units is to check connection on the binding posts. Most of them come loose and if that's the case you will get voltage drop readings deceiving you on the real results. I own both ET5410A and ET5420A and they act defective because of that. After tight good all binding posts this units are working fine.

Hi there,
I own the EastTester ET5411 and have the same problem when trying to connect the ET4511 via USB/ com3 to a PC: "ET5410" do not match answer: "ET5411,V1.02.2034.029,09432030024,V1.11.2034.002" (there is no ET5411 in the search socket of the TestController SW).
On April 30iest, 2023 you posted, that you succeeded in editing the IDstring.
How did you do that?
Your help would be greatly appreciated
