• Press the READ key and the LCD will display a blinking “SIP” (Sampling In
Progress). The measured value will appear after approximately 25 seconds.
SOURCES OF INTERFERENCE
• Presence of floating debris and coarse sediment which settle out rapidly will give
false readings.
• The infrared light source used for C124 Haze meter can effectively minimize errors
due to coloured dissolved substances. This effect, named “true colour”, is a
common interference for most commercially available instruments operating in
the range of visible light.
• Air bubbles and the effect of vibrations that disturb the surface of the sample
will give false results.
• Dirty glassware could also affect readings along with scratched or edged cuvette.
LOG-ON-DEMAND
• The meter can store up to 199 measurements in the internal memory. Press
the STO key: the last measured value will be stored and the display will show
the reference number of the stored sample.
• When the maximum number of samples (199) is
reached, the LCD will display the "FULL" message
to warn the user that next value will overwrite the
oldest sample recorded.
All samples will be shifted (reference number reduced by one) and the ref. number
one will continue to indicate the oldest value. To confirm storing of the current
sample, press the STO button again.
CLEARING LOGGED DATA
• For clearing all data stored in memory, press
ALT+CLR keys: the meter will ask for confirmation
by displaying the "CLr" message.
Press ALT+CLR again to clear memory or any button to abort the operation.
