ADJUSTING THE LIGHT SOURCE

If the sample blank is highly colored or turbid, the light level

may be inadequate for a proper operation. This situation is

indicated by the activation of the ana-

lyzer system alarm relay and the

appearance of “E09” on the display.

Note This condition can also be caused by failure of the LED light

source.

It may be possible to compensate for inadequate light level

by adjusting the light source intensity, through the small ac-

cess holes provided. It is not necessary to disassemble the

plastic enclosure to access this trimmer.
