What is the effect of the “Straylight” value on photometer operation?
The straylight value is an indication of the optical conditions of the Light Scattering Chamber (LSC) at a given point in time and as such, do not have a tolerance range established. Increases in the straylight usually occur through ordinary usage over the annual calibration cycle. Sudden and/or catastrophic increases in the straylight value typically are the result of operator error or component failure and render the unit inoperable. Some examples of catastrophic failure are introduction of liquid to the scattering chamber, formation of condensation on the optics, large accumulations of solid particulate and breakage of discrete components within the LSC. Photometers which remain operable, even with elevated straylight values, are still capable of accurately measuring filter leakage values.
