Calibration Procedure - Hanna Instruments HI 847492 Instruction Manual

thermometer will be used to read the beer temperature.
• When the beer temperature is 0°C (32°F) place the cuvet in the meter and imediately start the
reading.
MEASUREMENT TIPS
• For a correct filling of the cuvet: the liquid in the cuvet forms a
meniscus; the bottom of this meniscus must be at the same
level of the 10 mL mark.

CALIBRATION PROCEDURE

It is recommended to calibrate the meter only with Hanna ready-to-use calibration standard solutions.
Alternatively, formazin standards can be used. The prepared formazin solutions should be close
to the default calibration points. The first point must be near 0 FTU, the second point between
10 and 20 FTU, the third point between 50 and 150 FTU and the fourth point between 700 and
900 FTU.
CALIBRATION
Calibration can be performed in two, three or four points. It is possible to interrupt calibration procedure
at any time by pressing ON/OFF.
• Turn the instrument on by pressing ON/OFF.
When the LCD displays "----", the instrument
is ready.
• Enter calibration mode by pressing CAL/RCL.
The display will show "CAL P.1".
• Place the <0.1 FTU standard cuvet into the
holder.
• Close the lid and press READ . "----" and the
"LED and Read Status" indicator will blink on
the display.
