Altimeter An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level.The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under water.he greater the altitude the lower the pressure. When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is called a pressure altimeter or barometric altimeter.

ALTERNATOR WARNING LIGHT What does that little red light that says ALT mean when it comes on? Very basically, it means that either the alternator output voltage is lower than the battery voltage, or the battery voltage is lower than the alternator output voltage.

My Blood ALT Level is high. What does it mean? ALT is an enzyme (chemical) that is normally produced by your liver and found in your blood. It aids in the metabolism (digestion and processing) of certain amino acids (parts of proteins). It used as a surrogate indicator of liver damage.Most problems with the liver cause the ALT to be elevated.However, an elevated ALT (in the range yours is) does not necessarily mean that there is a major problem with the liver. Certain drugs and supplements can put strain on the liver, causing the ALT to go up.t used as a surrogate indicator of liver damage. Most problems with the liver cause the ALT to be elevated. However, an elevated ALT (in the range yours is) does not necessarily mean that there is a major problem with the liver.

ACCURACY OF AIRCRAFT BAROMETRIC ALTIMETERS The instrumental accuracy of such air data computers is usually approx. +/- 15 m in the zero altitude above sea level, whereas in mechanical altimeters, the value approx. +/-6 m is usually mentioned. The great accuracy of the modern air data computers has enabled to established a new system of the flight levels, the so called Reduced Vertical Separation Minimum (RVSM).

- In aviation, pressure altitude is the indicated altitude when an altimeter is set to an agreed baseline pressure setting under certain circumstances where the aircraft's altimeter would be unable to give a useful readout of altitude.

Accelerometer An accelerometer is a device that measures proper acceleration.[1] Proper acceleration, being the acceleration (or rate of change of velocity) of a body in its own instantaneous rest frame,[2] is not the same as coordinate acceleration, being the acceleration in a fixed coordinate system.

What is ALTIMETER? What is ALTIMETER? A barometer that is aneroid and measures altitude from the atmospheric pressure and the decrease in it with height. The instruments dial is graduated and the altitude is read in metres or feet. See encoding altimeter, recording meter. Related Terms.

- An altimeter will only read correctly under conditions for which it is calibrated temperature; Standard Atmospheric Conditions which assumes a temperature lapse rate of 1.98oC for every 1000ft increase in altitude and a sea level pressure of 1013.25 hPa. In this case an altimeter will show the pressure altitude.

- How does a pressure altimeter work? Photo: Left: A pressure altimeter is a more sophisticated version of an aneroid barometer, like this. Instead of showing the pressure on the dial, it shows height—but that's okay because there is an exact correlation between the two.

How FitBit Works In October 2011, the clip itself was upgraded and renamed the FitBit Ultra. The Ultra has the same features as the original FitBit, with one major addition: an altimeter. With the altimeter, Ultra knows how much elevation you lose or gain throughout a day. That's valuable information because inclines are hard work.

- Also, radar is the only. reliable way to measure an aircraft's height above the Earth's surface. Compared. with ordinary altimeters, radar is expensive, heavy, and complicated. An ordinary aircraft altimeter is nothing more than a sensitive barometer, an instrument. that measures air pressure.

- The altimeter measures the height of the glider above a given atmospheric pressure level by measuring atmospheric pressure in flight. Since the altimeter is the only instrument that gives altitude information, the altimeter is one of the most important instruments in the glider. The altimeter is a simple aneroid barometer that measures pressure at its current location.

What Does ALT (SGPT) Mean in a Blood Test? Quick Answer. The ALT test checks the level of alanine aminotransferase in the blood to see if the liver is healthy. Elevated levels of the enzyme could indicate damage caused by trauma or a disease process, such as cirrhosis or a strain of hepatitis, as stated by WebMD. Continue Reading.

pulse oximeter pulse oximeter. A device for the continuous monitoring of the blood oxygen levels, both by visible and audible means, during general anaesthesia. This is a major aid to patient safety as a very small drop in blood oxygenation is immediately apparent, alerting the anaesthetist to investigate the cause.

What does 'Altimeter 2992' mean? An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose. The altimeter uses the changes in atmospheric pressure to determine the changes in altitude.

Pulse oximetry A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram.ulse oximetry measures solely hemoglobin saturation, not ventilation and is not a complete measure of respiratory sufficiency. It is not a substitute for blood gases checked in a laboratory, because it gives no indication of base deficit, carbon dioxide levels, blood pH, or bicarbonate (HCO 3 −) concentration.

Altimeter The aneroid altimeter is calibrated to show the pressure directly as an altitude above mean sea level, in accordance with a mathematical model defined by the International Standard Atmosphere (ISA).he greater the altitude the lower the pressure. When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is called a pressure altimeter or barometric altimeter.
