3. General information
3.1 Intended use
The refractometer is a measuring instrument for determining the refractive index of
transparent substances in the liquid or the solid state. It is used to observe the
behaviour of light as it passes from a prism with known properties to the substance
being tested.
Use of the refractometer for other purposes is contrary to its intended use and may
be hazardous. The manufacturer shall not be liable for any damages caused
by improper use.
3.2 Warranty
The warranty shall be void in the event of:
▸ Failure to observe the instructions in the operating manual
▸ Use for purposes other than those described
▸ Modifications or opening the device housing
▸ Mechanical damage and/or damage resulting from media, liquids,
natural wear and tear
4. Basic safety information
4.1 Follow the instructions in the operating manual
▸ Carefully read through the operating manual even if you have prior
experience with KERN refractometers.
▸ Every language version includes a non-authoritative translation.
The original German document is the definitive version.
4.2 Warning
▸ Do not let acids come into contact with skin or eyes. If acid comes into contact
with skin, flush with copious amounts of water. Shower if larger areas of skin are
affected.
▸ If acid comes into contact with eyes, keep the eyelid open and flush the eye with
running lukewarm water from the outer corner to the inner corner. Flush eyes for
at least 15 minutes. Then consult a doctor or ophthalmologist immediately.
▸ Thoroughly clean the refractometer aer each use.
▸ The refractometer must not be exposed to extreme temperatures, high
mechanical stresses, strong direct sunlight or high humidity.
▸ This refractometer is not a toy. Keep out of reach of children.
▸ Make sure that you will not be hit by anything else while you are using the
refractometer, as this could cause serious eye injuries
▸ The rubber eyeshade may cause irritation when in prolonged contact with the
skin. If this happens, consult your doctor.
▸ Do not touch the lenses with your fingers.
6. Before the first use
Remove the protective film
(
if present
)
from the prism surface
[
2
]
and check that
the rubber eye-cup
[
4
]
is fitted correctly.
7. Use/measurement
The refractometer can be used to quickly and accurately determine the refractive
index of transparent substances, liquid or solid ones. To ensure correct measure-
ment, the measuring device should be adjusted before measurements are carried
out. Please make sure your hands are dry before handling the measuring device.
5. Supplied items
Aer unpacking and before using the device for the first time, check that all
listed parts have been supplied. Replace damaged or faulty parts immediately
and do not put them into operation.
▸ Refractometer
▸ Storage box
▸ Pipette
▸ Adjustment tool
▸ Cleaning cloth
▸ alibration Cliquid (Distilled water)

7.1 Zero point calibration
▸ Hold up the refractometer against a sufficiently bright light source and look through
the eyepiece
[
5
]
, holding the rubber eyeshade
[
4
]
closely against your eye/glasses.
▸ Rotate the eyepiece
[
5
]
to adjust it for your eyesight, until you can see the scale
sharply.
▸ Open the prism cover
[
1
]
.
▸ Thoroughly clean the prism
[
2
]
and the underside of the prism cover
[
1
]
using a so
cloth or soft paper
(
with alcohol if necessary
)
and wipe dry.
▸ Now apply a few drops of the calibration liquid
[
10
]
onto the prism surface
[
2
]
.
▸ lose the prism cover C
[
1
]
. The amount of fluid should be sufficient to moisten most
of the prism surface. There should not be any air bubbles between the measuring
prism
[
2
]
and prism cover
[
1
]
.
▸ Wait about 30 seconds to allow the temperatures of the fluid and prism to
equalise.
▸ Look through the eyepiece
[
4
]
while pointing the refractometer‘s prism surface
[
2
]
at a bright light source.
▸ Through the eyepiece
[
4
]
, you will see a bright and a blue field. The boundary line
between them shows the value on the scale which is also visible measured
through the eyepiece
[
4
]
.
▸ Use the supplied adjustment tool
[
11
]
to turn the adjustment screw
[
3
]
behind
the prism surface
[
2
]
(
under the rubber cap
)
, and adjust the scale so that the
measuring device is optimally set up by moving the boundary line upwards or downwards.
Calibration value ORA 2PA/2PB: 1,000 sgU (Urine) / 1,333 nD (Refractive index)
Calibration value ORA 5PB: 1,000 sgU (Urine cat/dog)
▸ Repeat step 4
(
cleaning
)
.
Important!
The ambient/room temperature and the sample temperature influ-ence
the refractometer measuring result. The scales of the refractometer
models, which have " B" in its name, are designed for an ambient P
7.2 Additional advice
It is important that the samples being measured are representative samples. For
samples that evaporate easily, measurements should be carried out quickly. The
samples should be at the same temperature as the measuring instrument in order
to achieve an accurate result.
7.3 Measuring procedure
▸ Make sure your hands are dry before handling the refractometer.
▸ Open the prism cover
[
1
]
and use the supplied pipette
[
8
]
to apply a few drops of
the sample liquid
[
8
]
onto the prism surface
[
2
]
. Close the prism cover
[
1
]
. Spread
the liquid evenly by pressing down on the prism cover
[
1
]
and elimi-nate any air
bubbles present.⇨
▸ Hold the device horizontally and wait about 30 seconds
(
for optimal tempera-ture
equalisation between the sample and device
)
.
▸ View the measurement scale through the eyepiece
[
4
]
. Point the prism surface
[
2
]
of the refractometer at a bright light source while doing this.
▸ Rotate the adjustment ring
[
5
]
on the eyepiece
[
4
]
to adjust the focus.
▸ The boundary line will move on the measurement scale depending on the concen-
tration. This bright/dark boundary line shows the result on the scale.
▸ Carefully clean the supplied pipette
[
8
]
and the refractometer after carrying out
the measurement.
Important!
Aer every measurement, use a lint-free, absorbent cloth to remove
the fluids from the prism surface
[
2
]
and prism cover
[
1
]
. Then
carefully clean the prism and prism cover using a cloth moistened
with water or if necessary alcohol, and dry both parts using a so,
dry and lint-free cloth. Avoid rubbing the prism
[

]
.

8. Cleaning and maintenance
Clean the refractometer using a so, lint-free cloth moistened with either water
or, if necessary, alcohol. Do not use any aggressive or abrasive cleaning agents.
Never immerse the device in water or hold it under running water. Never handle the
device with wet or damp hands.
Never touch the measuring prism
[
2
]
with hard tools made from plastic, wood,
rubber, metal, glass etc. Hard objects can quickly damage the relatively so prism
glass, resulting in measurement errors.
The refractometer is maintenance-free.
Cleaning should be carried out immediately before and aer each use of the refrac-
tometer to maximise its life and optimise measurement results.
9. Storage
Store the refractometer in a dry, non-corrosive environment, preferably
between 10 °C and 30 °C.
10. Service
Aer reading this operating manual, if you have any questions about setting up
or using the refractometer, or if any unexpected problem occurs, please contact
your dealer. The device housing may only be opened by trained service technicians
authorised by KERN.
11. Disposal
The packaging consists of environmentally friendly materials which can be disposed
of via local recycling facilities.
The device and storage box should be disposed of by the operator in accordance
with applicable national or regional regulations at the place of use.
12. Additional information
The product may differ slightly from the illustrations. Avoid exposing the refracto-
meter to direct sunlight. Never bring the refractometer into contact with solvents.
!
temperature of +20 °C! If the measurements are carried out at a temperature other than +20 °C,
the results must be correspondingly corrected.
Refractometer models, which have " A" in its name, are equipped with an automatic P
temperature compensation (ATC). Between +10°C and +30°C measurement differences due to
temperature changes are automatically compensated.
