Were you able to see what the RPM was on the VIR? I believe that the RPM readings are averaged across the passing sub-samples, so you may not have to worry about it. I have never tried the cigarette lighter adapter, but so far the alligator clip method has been rock-solid for me (I just wish that the lead was about 10 feet longer).
When doing the Gas Cap calibration you MUST pay attention to the monitor
and detach the calibration "gizmo" OPUS uses instead of Pass and Fail Caps,
AS SOON AS THE SCREEN SAYS Disconnect.
Or else you will get a failed gas cap calibration.
Been there done that in the short period of time, 3-weeks, with the OPUS GEN 3.
Don came in the other day to drop off two fresh calibration tanks and give me a new gas cap calibration apparatus. It plugs into the quick-disconnect and has a spigot that switches between the green and red calibration orifices, completely eliminating the calibration caps. He told me that it's totally legit, and has been the new "repair" for any Gen 3 user with gas cap calibration problems.
I haven't had any bench calibration problems at all yet, coming up on four months.
On my Gen 3, I have my zero air bottle regulated at 40 psi. My dyno lift and Gen 3 purge air umbilical are regulated at 45 psi from the 150 psi shop air, and the regulator on the back of the Gen 3 is set at 35 psi.
Ours ran great for 3 weeks and then error "systest.exe didn't start" happened while I was preconditioning an asm with the help rpm screen up. Tecn comes out and says bench is bad and they're on backorder. No idea when they'll have 'em. I have an idea that the BAR 97 spec says loaner after 3 days down.
Now, it HAS been through a power outage, but not during this or any other test, it was sitting idle and didn't seem fazed. I heard they were super sensitive to that, and it was the first thing the tech asked about.
Spec says it's supposed to handle surges, harmonics, and at least 12v fluctuations without losing accuracy, but nothing about losing a bench when the lights go out I'm wondering about an UPS so I could have time to shut it down when the power goes off. Anyone used one? (or an FedEx?) Also, is anyone using their gen 2 as a backup? I only have 2 bays and 1 dyno, so I can't run them simultaneously, but I was wondering if the gen 2 could be slid in when this shitpile goes south. Don't get me wrong, I do like it (and dislike it like everybody else) but when it's a piece of shit, it don't really matter.
Kind of makes me wonder what goes on during certifications. I see a conference room, piles of money, and the smell of ass. Disgusting.
That is the second one since 1998. The first one quit last year. It wouldn't charge the backup battery. A UPS (not FedEx) has protected my SnapOn machine from going down for all that time. When we have thunderstorms, and buckets of rain falling, the lights may go out, but my EIS, OIS, and billing computers keep going. I can shut down, and not lose any data. It's supposed to have surge protection, but I've never checked with any of my meters to confirm that.
