Optics failure
If the lenses are not reading correctly on the DX 260 then it would be worth checking/cleaning the
lenses for the smoke meter, to clean the Lenses:-
Take panel on the ends off > pull out the LED holder > check the Lens of the LED is clean > isn’t
RED inside (otherwise the seal at the back has leaked)> replace LED holder back into device > put
panel back on > retest
Cleaning the Lenses
Two lenses are fitted in the smokehead, one at either end.
The Smokemeter checks the cleanliness of the lenses at the start of each test, and the PC will
provide a warning when cleaning is required.
Accessing a Lens
The cleaning procedure is as follows.
• If fitted, remove the sampling probe.
• Unscrew the knurled knob at the sampling probe end of the sampling head and remove
the end cap.
• Carefully pull out the lens housing and wipe the lens with a soft cloth (if required, a little
methylated spirit will assist cleaning).
• Refit the lens housing with the arrow pointing upwards (a little silicon grease on the 'O'
ring will assist fitment – but do not get on the lens!).
• Refit the end cap and tighten the knurled knob.
• NOTE: Ensure the end cap locates fully against the body of the sampling head before
tightening the knob. If not correctly located, the lens housing is probably not fully home.
• Clean the lens at the other end of the smokehead in the same way.
• NOTE: The end cap for the sampling probe must be fitted at the end away from the
sampling head cable.
Blip test Fail (Microphone failure)
If the microphone fails then this needs to be exchanged as there is nothing the customer can do
to replace the damaged microphone (usually due to excessive heat damage).
