PRECAUTIONS FOR ACCURATE MEASUREMENTS
• The sample must not content any particles.
• The test tube must be dry on the outside without finger prints or oil or
impurities. If necessary, clean it and wipe it dry - do not use abrasive
cleaners.
• Shaking with the reagent may cause gas bubbles (therefore a highest
measured value). Before to place the test tube inside the tube holder,
move gently the test tube until all gas bubbles disappear.
• Do not wait between end of reagent mixing and measurement in order
to warranty the highest possible accuracy.
• Empty, clean, rinse and dry the test tube, as soon as possible, in order
not to colour it and decrease the quality of next test.
DISPLAY OF ERROR MESSAGES
Light High:
Too much transmitted light.
Check the zero operation
Light Low:
Too weak transmitted light.
Check the zero operation
Inverted test tubes:
Test tubes, on zero and test,
have been exchanged.
Repeat the test operation.
Under range:
Blinking display
“0.00”
shows a
sample with less absorption than the zero test.
Repeat the zero operation.
Over range:
Blinking display
“2.50”
indicates an
over range of sample.
Proceed to dilute carefully the sample and proceed
to a new test.
Battery low:
Change the battery as soon as possible.
Dead battery:
Change immediately the battery
With such a displayed message, all running test
parameters are lost.
BATTERY LIFE TIME
• The meter automatically turns off after 2 minutes of non-use or 10 seconds
after measurement display.
One fresh battery lasts for about 5000 measurements, depending on
the light level. When the battery capacity is lower than 10%
"bAt"
appears on the LCD at start-up.
If the battery is empty and accurate measurement can't be done any
more, the instrument shows
“bAd”
then
“bAt”
each for 1 second and
turns off. To restart the instrument, replace the battery by a fresh one.
BATTERY REPLACEMENT
• Turn the instrument off, if not yet, by holding the button until the meter
shuts off.
• Turn the instrument upside down and remove the battery cover with a
screw driver.
• Remove the battery from its location and replace it by a fresh one.
• Insert the battery cover and replace the screw with a screwdriver.
