Operation
Taking test samples (figures on page XIII)
Recommendation: Take the test samples
as directly as possible at the brake calli-
pers and wheel cylinders. When you take
the brake fluid, observe the fluid level in
the expansion tank.
Measurement values for samples from
the expansion tank are generally higher
than those for samples from the wheel
brakes as just one insignificant fluid ex-
change takes place in the brake system.
Brake fluid, which has been refilled in the
expansion tank, can falsify the measure-
ment result over several weeks.
Avoid falsifying the measurement results.
Use a new pipette and a new, clean sam-
ple beaker for every measuring process.
Important: Risk of damage to or destruc-
tion of the sensor head.
Do not carry
out any dry runs! Clean the sensor head
before the first measurement. To do this,
carry out two to three measurements with
new brake fluid.
To test the brake fluid, see figures
on the fold-out page.
Testing the brake fluid
Measuring (figures on page III)
1. Lift the measuring arm and place the
new sample beaker on the base
2. Fill the sample beaker to the brim
using a new pipette
3. Lower the measuring arm until the
sensor head is resting on the bottom
of the sample beaker. This will cause
some of the brake fluid to overflow,
which is collected in the sample
beaker's overflow channel
4. Press the “Start” button
= The “Start” indicator lamp flashes.
CAUTION! Hot sensor head! Risk of
burns. Do not touch the hot sensor
head.
The current measured temperature
is shown continuously on the display
during the heating and boiling phase.
When the “Start” indicator lamp stays
on permanently, the boiling point has
been reached. The measurement value
remains visible until the next test. For
permissible measurement results, see the
table below.
CAUTION! Hot brake fluid! Risk of
burns. Leave the brake fluid to cool
before removing the sample beaker.
5. Lift the measuring arm and remove
the sample beaker
6. Dispose of the beaker and fluid in an
environmentally friendly manner
