Error of the Yu 16 luxmeter

Measurement Techniques Aims and scope

Conclusions

  1. 1.

    The quality of the F102 photoelements in Yu16 luxmeters is low and does not afford reliable operational capability to luxmeters over the course of several years, despite checks made at the established intervals.

  2. 2.

    The inadequate design of the absorbers for the luxmeters leads to their rapid contamination, with the consequence that more than 90% of the luxmeters have inadmissible error at the additional measurement limits.

  3. 3.

    The transparency of the material from which the absorbers are made is inversely affected by temperature, Heating of absorbers caused by the measured illumination changes the attenuation coefficient so much that measurement of high illuminations is unreliable with the Yu16 luxmeter.

  4. 4.

    It is urgently necessary that the “Vibrator” Works increase the quality of the F102 photoelements and change the design of the absorber, and also provide replacement of the photoelements and absorbers without the microam-meter.
