Why won't Dell s510 pen calibrate?


Needs an updated Driver. Update from the Device Manager on the Control Panel, or it is just a bad pen, take it back if it is bad

Haw do i calibrate metller toledo mp220 ph metter


1ST YOUR GONNA NEED BUFFERS:

All pH meters require calibration standards to ensure that the readings are traceable to a standard. Always choose a pH 7 buffer plus at least one other pH value close to your expected measurement range. Using solutions of known pH value allow you to adjust the system to read accurate measurements. Calibration should be performed before each reading or each set of readings.
After that this model has auto buffer select and it will tell You what buffer you put it in , also will ask if you want to correct it as well

The ph part on my test strips is brite pink why?


pH Scale
Examples of solutions on the pH Scale compared to distilled water are set out below:
  • pH = 0 => Battery Acid which is very strong Hydroflouric Acid
  • pH = 1 => Hydrochloric Acid secreted by stomach lining
  • pH = 2 => Lemon Juice, Gastric Acid, Vinegar
  • pH = 3 => Grapefruit Juice, Orange Juice, Soda
  • pH = 4 => Tomato Juice, Acid Rain
  • pH = 5 => Soft Drinking Water, Black Coffee
  • pH = 6 => *****, Saliva
  • pH = 7 => "Pure" Water
  • pH = 8 => Sea Water
  • pH = 9 => Baking Soda
  • pH = 10 => Great Salt Lake, Milk of Magnesia
  • pH = 11 => Amonia Solution
  • pH = 12 => Soapy Water
  • pH = 13 => Bleach, Oven Cleaner
  • pH = 14 => Liquid Drain Cleaner such as "Draino"


pH Scale Numbers
This scale is logarithmic. It means that each number is 10 times stronger than the preceding number. For example, a pH of 2 is ten times more acidic than a pH of 3 and one hundred times more acidic than a pH of 4. It is important to monitor pH because live depends on it. For instance, human blood is basic with a pH between 7.3 and 7.5. If the pH of blood drops below 7.3, acidosis occurs. If the blood pH rises above 7.5, alkalosis occurs. Death will occur if blood pH goes below 7.0 or above 7.8. Our human existence depends upon a balanced and buffered blood pH.

so u should seek medical attention

Wacom cintiq 12wx calibration


I had a similar issue using the 12wx with a 15" MacbookPro Retina. Screen displayed the desktop way too much to the left. I found that the refresh rate of 59.8 hertz seemed to not be compatible despite it automatically being set. After changing this to 74.9 Hertz, the desktop is now properly centered on the Wacom screen and can be calibrated now. Not sure if this applies to Windows machines but perhaps something to keep in mind.

Is this a automatic pH meter?

The only reliable way to measure your pH is by using a test kit. The automatic devices must be adjusted and set at least as often as the manufacturer recommends.

Your pH should be between 7.2 and 7.6. Your Alk should be at 100 (between 80 and 120) Get the Alk right before you try to get the pH at 7.2 or 7.4. These changes you are making should be measured over a number of days not a number of minutes, by the way. Alk 'buffers' pH and prevents pH 'bounce'.

Does your filter system run 24/7? Point of interest, most commercial pools should have a 8 hour turn over rate and run 24 hours a day for best results. Spa's should turn over on a 2 hour basis.

I don't know where you are writing from, the acceptible pH in the USA, generally, is 7.0 to 7.8. 7.0, while not really bad, is more acid than most swimmers can enjoy.

Other considerations: Your calcium should be around 250/300 ppm. Outside pool? Cyanuric Acid should be around 70 - 80 ppm. CL should be around 4 ppm. If you are using Bromine, the Br number is 2 X the CL number. By the way, Bromine is about 2 X more expensive than CL. Might you be using salt and making your CL? Salt should be 3200 to 3400 ppm and you should monitor your CL and adjust daily to get your 2 to 4 PPM cl. You MUST protect this CL with Cyanuric Acid.

I hope you find this information helpful. The courtesy of a positive vote will be appreciated.

Thank you for your interest n FixYa.com

Agriculture Application of Round-up


Very important to buffer the pH of the water at pH 5. Then add Roundup /Glyphosate 360 at a 2% for grass weeds and 3% for brush weeds. Ensure that the grass is dry when treating and no rain is expected within 6 hours. Please take care with roundup as it is poison .

I can't promise this is a fix for your tv, but I've had two so far with that same ailment. You need to replace the YSUS and BOTH buffers, if you want to do it one at a time to avoid any unnecessary costs, pull them and look them over carefully. If you see any burns on the bottom of the boards or if the hot glue around the heat sinks has gone brown, thats a telltale sign that the chip underneath is toast. Here's the next problem. Those buffers aint cheap....ebay's best price is about $150 each. Start with replacing the Ysus, then move on to the buffers. If you need help or advise in your dismantle, let me know and I'll send photos. Good Luck.

Touch screen not working


Hpoe this helps, had the same problem with my son's leapster2, took it back got a replacement and the same thing happened within 5 minutes of turning it on!! Finally found this advice on the net.

If your Leapster2 does not respond to the stylus pen, it needs to be calibrated. Calibrating the Leapster2 is easy:
1) Ensure that a cartridge is not inserted
2) Hold down the Hint button while turning the unit on
3) When the LEAPSTER menu screen appears, press the A button
4) Touch each of the crosshairs that appear with the stylus
5) Restart unit

Good luck, seemed to work for ours

Modifications to my 2008 subaru liberty non turbo 5 speed man


Start with a higher flowing airfilter( a replacement panel one in your factory airbox,as a pod filter will **** hot air and off set any flow gains that it gives) a larger diameter exhuast is next and im unsure of what sensors are in your 08 subaru but theres always away of getting around it. They are the best bang for buck modifications you can do and should net you 7-10kw at the wheels, most things after that can get expensive after that on a N/A motor and the airfilter is easy to do yourself , any exhaust place can take care of your exhaust. help this helps.
