not covered by our warranty.
• The device must only be used as described in this instruction manual. If used otherwise,
this can cause dangerous situations for the user and damage to the meter.
• The instrument may only be used if the environmental conditions (temperature, relative
humidity, …) are within the ranges stated in the technical specifications. Do not expose
the device to extreme temperatures, direct sunlight, extreme humidity or moisture.
• Do not expose the device to shocks or strong vibrations.
• The case should only be opened by qualified PCE Instruments personnel.
• Never use the instrument when your hands are wet.
• You must not make any technical changes to the device.
• The appliance should only be cleaned with a damp cloth. Use only pH-neutral cleaner,
no abrasives or solvents.
• The device must only be used with accessories from PCE Instruments or equivalent.
• Before each use, inspect the case for visible damage. If any damage is visible, do not
use the device.
• Do not use the instrument in explosive atmospheres.
• The measurement range as stated in the specifications must not be exceeded under
any circumstances.
• Non-observance of the safety notes can cause damage to the device and injuries to

2 Operation
At the beginning of the measuring process, the prism cover and prism must be carefully cleaned
and then dried. Now place 1-2 drops of the sample on the prism. When the prism cover is
closed, the sample is distributed evenly between the cover and prism. To place the sample on
the prism, you can use the pipette. Please ensure that no air bubbles are formed - this would
impair the measurement result. By moving the prism cover slightly, the sample liquid can be
distributed evenly. Switch on the LED illumination on the prism cover and look through the
eyepiece. By turning the eyepiece, you can adjust the sharpness of the displayed scale. The
value can be read from the line between the light/dark boundary. To prevent deposits from
forming on the prism and its cover, the instrument should be carefully cleaned and dried after
each measurement. Clean the refractometer with a soft cloth. Never clean the instrument with
running water as this could enter the LED illumination in the prism cover and lead to its
destruction.
The refractometers work according to the principle of light refraction. With these instruments you
can easily and accurately determine the concentration of e. g. starch, glues, adhesives, etc., the
mixing ratio of liquid media and the sugar content of milk, juice, wine, etc. Therefore, the
instruments can be used in many industries as a quick measuring instrument in production and
laboratory. Several models, all with automatic temperature compensation (ATC), are available.

5 Calibration
The instrument must also be carefully cleaned and dried before calibration. Now apply 1-2 drops
of distilled water to the prism. If the light/dark line is not at 0 % (waterline), this can be adjusted
using the calibration screw on the top of the instrument, behind the prism cover. The screwdriver
included in the delivery is used for this purpose.
6 Important notes:
• The prism cover and the prism should be kept clean; dirt impairs the measuring
accuracy.
• Avoid scratches on the prism and the hinged cover; these also have a negative effect
on the measurement.
• Do not use harsh, aggressive cleaning agents but only a damp cloth. Then dry the
device well. Never clean the unit under water as this could enter the instrument.
• Avoid shocks and impacts as this can destroy the optics.
• Store the instrument in a dry place.

8 Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
If you have any questions, please contact PCE Instruments.
