The replacement time of the tungsten lamp is approximately 1,500 hours. To check the W lamp
intensity:
1) Power on the unit if it is not already on. Wait approximately 10 minutes.
2) Set the wavelength to 720nm by YL-Clarity software.
3) Select the Reference Light Intensity.
4) If the displayed value is less than a half of the original intensity, the lamp should be replaced to
new one. Generally, you have to consider the lamp exchange when the light intensity of reference
energy is less than 5 nA.
