Two tasks have been started to improve "up-time".
- Aided Circuit Card Testing
- Aided Relay Testing
I'm using the word "Aided" to help avoid unrealistic expectations.
Actually, Grant Saviers started designing and drumming up support for an SMS card tester system since about Spring 2005 when we finally got adequate 50 Hz power. Support was slow in coming. So Grant continued designing with little moral support. Likely he figured that good, but not perfect, was better than nothing at all -
- - cards were being adequately repaired by Tim Coslett
- - many people (especially Ed Thelen - me - ) remembered many cards being shipped to sites as "repaired" or "no problem found" that were defective. These people wished a "perfect" card tester, including verifying voltage tolerances, ability to drive rated loads, perform at rated speed, functional temperature range and maybe even vibration sensitivity.
Then Tim Coslett moved to Montana, and Jim Hunt took over fixing SMS cards.
Then Jim got a day job and was not available.So, in 2014 George Ahern linked up with Grant Saviers and started fabricating Grant's designs.
