Does the phototachometer need to be calibrated? How often? And does the company provide calibration?

No calibration required. It counts reflected light pulses. I've had one for some time with no issues and I use mine on a daily basis. I'm a marine diesel technician, I put reflective tape onthe vibration dampner reads every time. I had compared it to more expensive photo TACHS from snap-on and Mac and this one is dead on every time.

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.

It should either work correctly or not at all. If you have access to an old-style magnetic ballast fluorescent light, point it at the light and take a reading (light on, of course). You should get a reading of 7200 rpm - the light actually turns on and off twice with each cycle of the AC power, so 2 times 60 cycles per second times 60 seconds is 7200. This may also work with mercury and sodium vapor lights, but it will not work with more modern lights with electronic ballasts.

I suggest using the lens IS if you have the latest firmware installed with this lens. With a long telephoto lens like this the best thing to do is let the lens do the correction.

No it does not. Saw no reference to calibration, just 1 yr limited warranty.

I do not recall anything about calibration and I no longer have it. After spending two days with very unusual readings, I threw it in the trash. I purchased a used military compass which still works after 30 years.

I checked the users guide and do not see any information about calibration of the unit. There is a support number you can call.

I have never had my camera recalibrated. I do clean it prior to every shoot with a sony cleaning tape. If you don't do that the new tape will stall and skip. If you are going from the camera to the computer it will not affect the picture quality of the tape.

Yes according to the directions. I bought it for that purpose, suitcases and shipping boxes. I've not yet had the opportubity to use it for them. Instructions have about 6 steps to calibrate.

The DC1100 does not provide a user accessible calibration method. One question is what would you use for calibrating it if you could adjust it? My best answer is that you should contact Dylos at: support@dylosproducts.com - The product's readings can be affected if it is put too close to a fluorescent lamp, and readings may vary depending on different locations in the same room. I am very happy with the monitoring ability when checking for effectiveness of my room air purifier. But, try Dylos Tech Support's email for more authoritative info.

Mine wasn't easy to calibrate. You need to press a button on the back and go around a block - - - a complete 360 degree turn. You may have to do this several times to get it to be reasonably accurate. Good luck.

It self calibrated when I first set it up. I have moved it twice since then with no problems.

No it is not. But it has been very dependable for us. You should calibrate at least once a week. The cost of this meter is cheaper than a higher end units probe. be careful the probe is not a water tight. Hope this helps.

Totally agree. If a person isn't doing monitor calibrations with a colorimeter like the Spyder -- not by eyeball! -- on a reasonable schedule, they can pretty much expect to have color management problems. Folks who are quick-printing snapshots straight out of their point-and-shoots may not be interested in making the effort, but someone who's willing to invest in a nice printer like this, probably ought to be calibrating their monitor. Just my $0.02.

I have not yet encountered this problem. I would think re-calibration would have to be done by service technician people. I do not find any measurement "0 in" feature in on my unit, such as what my digital micrometer has. To be accurate, a definate test fixture would need to be used for calibration.

It calibrates the lenses. The camera (Canon Mark III) has the settings for the micro adjustments needed. Short answer ...Absolutely

yes, when I received my refractometer it was dead on. in the instruction you can test the refractor with distilled or RO water to calibrate the refractor.

I sure don't! I bought this one and a Sun Master digital and they couldn't read further apart! What we need to find is a calibration solution that works on soil meters, not just water meters.

The only answer to your question that I have is that I didn't have to calibrate mine, and it seems to work correctly. This is not a hi-tech compass. It's pretty cheap overall. But if you can't afford a good one, it works in a pinch. It sticks to your window wherever it is convenient for you.
