Fujitsu Denso EUL-75JL electronic load calibration
« on: October 27, 2020, 11:25:04 am »
I bought an old (2001) electronic load EUL-75JL.
At first glance everything is fine, but the current meter has an error of about 100mA.

The current meter shows 100mA in "HI" mode without load and 0.0357A in "Low" mode.
The instrument has a calibration function and I am sure it can be corrected.
I could not find user manual or service manual.
The calibration menu has 31 items and without instructions it is impossible to understand what each particular item is responsible for.
There are no variable resistors inside, completely digital design.

Do you guys have any ideas?
