• Battery acid tester
- Battery acid Scale A
The scale indicates the density of the battery acid in kg per litre.
Scale A indicates the ranges for RECHARGE, FAIR and GOOD.
• adBlue ® Evaluation Scale B
- The urea concentration of AdBlue
- Display values between 33.3 and 31.8 % by weight are within the tolerance range
to ISO 22241-1 (observe manufacturers's specification)
• anti-freeze tester
- Coolant Scale C, propylene glycol (G12++) at left, ethylene glycol (G13) at right
- Windscreen washer fluid Scale D (guideline)
The instrument incorporates a display, subdivided into three scales, from which the values for the respective fluids can
be read off (see illustration). Propylenes are used predominantly as an antifreeze agent outside Europe. Ethylenes are
used predominantly as an antifreeze agent in Europe.
Take particular care when testing the battery acid. Do not let it come into contact with the
eyes or skin – this could be harmful. Clean the prism with clean water und dry it with a
soft cloth after every test procedure!
• test procedure:
- Check that the prism (2) and lid (1) of the instrument are clean.
- With the pipette supplied, place a drop of the fluid you wish to test on the prism (2).
- Close the lid (1); this will disperse the fluid.
- Turn the eyepiece (3) so that it is properly focused.
- Read off the value on the corresponding scale – a pronounced LIGHT-DARK dividing line (4) is displayed.
- On the completion of each test, carefully clean the prism (with a dry cloth).
Note: Due to variations in the formulations of windscreen washer fluids, the result of this test represents an
average value for a variety of alcohol-based anti-freeze mixtures. The accuracy of the test instrument display can
be checked with distilled water. The LIGHT-DARK dividing line must coincide with the WATERLINE.
If the check reveals inaccuracies, return the instrument to your dealer or direct to the manufacturer.
