Manipulate this instrument with care.
Avoid mecanical shocks, high or low temperatures, humidity.
Do not let moisture deteriorate the meter.
How to do a corrected measurement:
•Open the hatch on the right side
•Choose the LOT number according to
the table on the right and select it in the
device´s setting with the ▲▼- buttons.
•Insert test strip in strip carrier and close
the hatch.
•When ,,GO“ appears in the display,
open the hatch again. Take the strip
and dip it immediately for 2 sec. into the
solution to be tested. Shake off
remaining solution
•Meanwhile, the device counts down
from 60 to 0. Having reached 5 (sec.),
insert the test strip again and close the
hatch.
•The display now shows the corrected
result.
Attention:
If the determined correction factor is lower 0.8 or higher 1.2, it is advisable to
choose LOT 5 for measurement and correct the measured value manually
(calculator).
Correction factors of such extreme values appear very rarely.
1. Choose LOT number 5
2. Make 3 single measurements with calibration solution 100 mg/l NO3
3. Calculate the average value of the 3 measurements
4. Correction factor KF = 100 : average value
