Accuracy and calibration... Posted by Larry West [Email] ![]() ![]() ![]() In Reply to: How the OEM gauge could be accurate since there's no, CDT, Sat, 15 May 2010 09:05:59 Members do not see ads below this line. - Help Keep This Site Online - Signup |
are NOT the same thing!
Accuracy of (in this case) a boost (or other) gauge means that for a given input, all gauges register the same deflection of the needle.
"Graduated" means that someone has been nice enough to place markings on the face that help the observer to determine the exact value of that deflection. The Saab boost and temp gauges are not graduated.
"Calibrated" usually means that the device was tested against a known standard, and determined to read the same as the standard, and/or adjusted to the standard. Devices like that are often precise, and costly, or are used in industries where precision and accuracy are paramount (think aircraft mechanic). When a device is calibrated, the source of the standard is known, and one can trace the calibration all the way back to the source.
Mind you, you can still be accurate without being calibrated...
