Recalibration value: Anyone have any thoughts on this?

Good calibration does save electrical costs. That's often shown in CNET HDTV reviews. But $250? Do they get a cut? I don't know about 6 months, but from time to time it probably doesn't hurt to use a calibration DVD (Digital Video Essentials: HD Basics [HD DVD]) or one of those THX calibration ones that come with some movies.

I have calibrated my set within 4/100 of a gm.That is using 100 gm calibrating weight.Not bad..

No.thougjt that as well.But i did get the values adjustment olnly because it was time.do it. It was a very good improvement as far horses power an looks.I am very happy with it nate.

I have used it about 12 times in about 6 weeks. The instructions say it needs recalibration every 6-12 months, or if used every day, it will need recalibrated in as early as a month. So that sounds like around 30 times? Instructions say it can fluctuate after limits have been met but for me so far, it still seems on target as I have had many road side tests. I hope it will last at least a year. They have a phone number and web address for info on recalibration. backtrack.com or 877-334-6876.

I've seen the R value listed somewhere in the .03 range where i do not recall

In addition to info. below-- do remember that it will need to be recalibrated every time you move it--even if moving it a little. I think that means doing what K. Jackson, below, said to do. Good luck...

Hello, The thermometer is not recalibratable. What you should do, is put the thermometer in a pot of water, just before it boils. When it boils, take note of reading. Water boils at 212deg. at sea level. the boiling temp. goes up as you gain altitude. But 212deg. is close enough to get an idea, of where you thermometer is reading. I would bet that most thermometers are plus/minus 15% anyway. They just give you an approximation, of where the food is..................RW

I can only speak for the one I received as the short directions didn't mention specific requirements for calibrating.It was only after I first attempted to calibrate that I became aware of this. I pushed the buttons according to the directions. A few seconds after it started a self-check, the screen flashed '1000.0g', which of course I didn't have. I did have a total of 1000.0g in a set of inexpensive calibration weights but I couldn't add them to the scale fast enough and the calibration was off accordingly.I did purchase on Amazon a single inexpensive non-certified 1000.0g calibration weight for $16.00 and it worked perfectly.I hope this helps you out.

You send it back to the manufacturer. It has a life time warranty. But I like mine so much and find it to be very accurate when compared to "regular cuffs" and stethoscope that I fully trust it. Just make sure you have the correct sized cuff for your arm! I have two sized cuffs--large for me and medium for other folks. I really doubt that recalibration would be needed for this monitor.

The documentation of this product did not say anything about calibration. Thus I assume it is already calibrated at the factory. But you bring up a good point. What if at some point the calibration may be off and what do we do? Documentation said nothing about this.

I really want to say, "I don't know." There is no real way to calibrate the device except by using my carpenter's level, which seems to say it's ok. Let's put it this way, it's better than I usually do when in a crooked situation. When I have a nice horizon, then the camera grid works best of all.

I have no way to verify accuracy since I don't have nist traceable standard weights. Precision seems OK. I have noticed that the scale sometimes doesn't want to zero. I'll turn it on and it moves away from zero (I have seen it go higher and lower). When it does this the zero may wander as much as 10 lbs. Eventually the scale stabilizes. I have not contacted the mfg. I find this annoying but am willing to live with it since it rarely happens.

Yes because the device calibrates it to match a standard calibration. So what you see is what other's see when they have also calibrated. Therefore it will calibrate them all to the same standard.

It seems to calibrate itself upon startup. It will calibrate itself to zero if you turn it on with a container that you intend to fill already on it. As for it's need to be calibrated for accuracy, we'll we just have to trust to the gods of electronics. That said, I've never felt it might be even slightly beyond negligible where error is concerned. I'll buy another if mine ever poops out!

I calibrated mine using a iOne calibration tool, granted it wasn't off by much but i needed to calibrate based on a different gamma value than the 2.2

Not sure, only had for 1 mo. Can use over and over and send back to co to recalibrate in 6 mo or longer. Depends on how many uses you have.

I've had my LR for 28 months. I've had to replace the entire unit twice, plus the globes three times because customer service insisted the problems had to be with the globe. They were not, and I wasted weeks having to pack up and exchange parts. In my experience, it is rare for the unit to work problem-free for much longer than a year at a time. Fortunately (aside from issues of inconvenience) those difficulties were covered under the warranty. My current LR (replaced in July of last year and no longer under warranty) is not working. Following are the options quoted to me in an email from customer service; as you can see, none of them are inexpensive. Each option is carefully calibrated so that the most expensive one is also the 'safest' value in terms of warranty. "It sound as if you are having a problem with the position sensor. Unfortunately, there really is no way for you to fix that at home. At this point we would recommend that we repair your base unit. The cost to repair is typically $46 to $104 plus return shipping cost of $35. Another option is our complete Tune-Up for $139 which includes the return shipping costs. With our Tune-Up option our technicians will replace the motor, wiring harness, circuit board, carbon filter and seal strips. In addition to the standard replacement items, our technicians will perform a 7 point inspection and replace any other worn or damaged components. And a final option would be to buy a new or reconditioned base with an existing customer discount of 15%. With the discount, a new base would be $203.15, and a reconditioned base with the discount would be $160.65. *Prices include shipping. Both new and reconditioned bases come with the standard 18 month full warranty."
