Frequently Asked Questions

Should I calibrate using mg/L solution or % saturation?

FAQ - Water Quality Sensors - HACH ENVIRONMENTAL
Standard methods for DO calibration suggest that a DO sensor should be calibrated to match a known mg/L standard or the mg/L measurement of a Winkler titration. However, air calibration using "% saturation" is considerably faster and easier, and does not require any known calibration solution.

What solution should I use to calibrate Turbidity?

FAQ - Water Quality Sensors - HACH ENVIRONMENTAL
Hydrolab recommends using Hach's StablCal solution for calibrating Turbidity. Another type of calibration solution is known as polymer beads. However, all sensors "see" polymer beads differently, so if this type of calibration solution is used, please confirm that the type sensor in use has been characterized to the specific sensor being calibrated.

Can I calibrate my transducers using your Analyzers? How?

Data Physics Corporation FAQ - General
Transducer Calibration software, standard on all analyzers since release 3.0, automates calibration of sound and vibration sensors and updates the Input Channels Table with the actual sensitivity of the transducer being used. Transducer Calibration can also be used with multi-output calibrators to calibrate multiple channels at the same time. A microphone icon in the Parameter Dialog tool bar opens the Transducer Calibration dialog box. Enter the parameters as needed and click START.

How much is 50 points (mg/dL) in mmol/L?

Diabetes-Daily-Care
mg/dL is equivalent to 2.8 mmol/L. There are two popular blood sugar level measuring systems: mg/dL used widely in the USA and some English speaking countries and mmol/L used in the rest of the world. Our guarantee then in mmol/L is "Drop 2.8 Points mmol/L in 30 Days - or it's FREE!".

Typical Analysis mg/l; what does that mean?

FAQs - Brecon Carreg
The typical analysis is the quantity of the reported minerals found in the natural mineral water. During the process to achieve mineral water status the water is tested by an external laboratory over all the seasons of a two year period. The water is tested regularly thereafter, and must be consistent with these figures. Mg/l is milligrams per litre and reflects the very small quantities of minerals which are being measured. There are other trace elements, which are analysed and monitored.

Mg/l are they high/low in comparison to other waters/permissible levels allowed?

FAQs - Brecon Carreg
Of course the reported minerals (and those not reported on the side of the pack) are within permissible levels. Of over 190 bottled waters available in the UK there are a variety of levels of minerals. Brecon Carreg is average overall ? taking a measure called dry residue. Within this the different mineral levels in Brecon Carreg vary relative to the UK average.

What does dry residue at 180oC/198 mg/l mean?

FAQs - Brecon Carreg
If one litre of Brecon Carreg is heated to 180oC all volatiles and combustibles are driven off. What remains behind is classed as the dry residue. The residue refers to a chemical procedure to measure the mineralization. In normal circumstances these minerals are in solution in the Natural Mineral Water; are consumed along with it, and processed by the body. There is no residue left behind in the bottle.

How often should I calibrate my instrument?

What is considered "normal" sensor weight loss? [Applicable to LD, RM, and PLC Series continuous monitoring systems, and portable sensors for formaldehyde and hydrazine]

Can I calibrate a module myself?

Synthesizers.com --- FAQ - Frequently Asked Questions
Sure, every module that requires calibration comes with calibration instructions. Usually this takes a good frequency counter, volt meter (4+ digits), oscilloscope, and a precise voltage source (+/-1mv). All modules are calibrated before shipping with very accurate test equipment so you don't have to worry about this, but many people like to know what all of those trim-pots are for on the PCB. Many modules require no calibration at all.

What is saturation?

Color FAQ - Frequently Asked Questions Color
Again from the CIE, saturation is the colourfulness of an area judged in proportion to its brightness. Saturation runs from neutral gray through pastel to saturated colours. Roughly speaking, the more an SPD is concentrated at one wavelength, the more saturated will be the associated colour. You can desaturate a colour by adding light that contains power at all wavelengths.

What do I look for when using the Simple Solution Spot Spotter™?

SimpleSolution
Under the Simple Solution Spot Spotter™ pet urine will fluoresce a dull yellow. On occasion, you will find other fluorescent material that will show up under the Simple Solution Spot Spotter™. Optical brighteners found in some detergents can leave a residue that will fluoresce a brilliant blue-white. Pet urine will appear as a weaker fluorescence when compared to these optical brighteners.

L-carnitine at 500 mg a day? What makes it so important?

All-Natural Pure Essentials for Mature Dogs - FAQ's - Senior...
L-carnitine is an amino acid. Deficiencies of L-carnitine have been linked as a possible contributing factor in dilated cardiomyopathy in dogs. This is the heart disease most dangerous to senior dogs. Powdered EFAs are the type used in tablet preparations. They are very good for your dog. They do provide the omega-3s so valuable in promoting good health. The amount in the Senior Dog product is not the amount needed to maximize the benefits of EFAs.

How can one change the blood glucose units from mmol/l to mg/dl?

AIDA v4 freeware diabetes software blood glucose simulator p...
In the downloadable (PC) version of AIDA - from the data entry screen - press the function key for "Options" and then press the letter key - a - to toggle (switch) the blood glucose units from mmol/l to mg/dl (or back again). In 'AIDA on-line' - scroll down the opening page to the heading which says "Options". Here under the first entry you will be able to select the blood glucose units that you prefer (mmol/l or mg/dl).

Did women who were pregnant when using contaminated L-tryptophan have healthy babies?

Eosinophilia-Myalgia Syndrome FAQ
I know of perhaps 5 to 10 cases of women who believe that using contaminated tryptophan while pregnant or nursing caused their children to have some symptoms of EMS, if not outright EMS. If you used LT and have EMS and think your child has EMS, you may wish to contact the national organization, write to me, or peruse my Support Page for links to these and other support groups.

Why do I have to calibrate?

Frequently Asked Questions About the MiniMed Paradigm? REAL-...
Calibration is like buying a watch and setting the time for the first time. Glucose sensors are similar in nature. To initialize a glucose sensor, you need to enter a meter reading to give the system a starting point. And, just as a watch needs to be adjusted occasionally, so does a glucose sensor. You need to enter at least two meter readings a day – once every 12 hours.

What are the benefits of using the 750 mg capsules?

Keflex | FAQ
Keflex 750 mg strength capsules, given twice daily, provide a simpler way to deliver a 1500 mg* total daily dose. It also provides more flexibility to deliver higher doses of cephalexin therapy with fewer capsules per day. Furthermore, by reducing daily dosing frequency and making dosing easier, Keflex 750 mg capsules could potentially improve patient compliance. Unfortunately, MRSA infections are resistant to all beta-lactam antibiotics, including cephalosporins such as cephalexin.
