bap8guy | ESI DV411 unit 4 - Rigged to Function @bap8guy | Uploaded February 2022 | Updated October 2024, 22 hours ago.
I purchased this DV411 for a good price, but unfortunately the linear potentiometer that provides the adjustment for the 4th and 5th decades was severely damaged. It will take time to find a suitable replacement, so I decided to "Gerry rig" a replacement. This video captures my "rig" and the subsequent testing of the unit, once completed. The unit works extremely well!!!
I will be using this unit as the divider for an upcoming 5 decimal place Voltage Reference project, soon to be published.
