2.2. Ensure safety
> Only operate the product properly, for its intended purpose and
within the parameters specified in the technical data. Do not
use any force.
> Do not operate the instrument if there are signs of damage at
the housing, mains unit or feed lines.
> The objects to be measured or the measurement environment
may also pose risks: Note the safety regulations valid in your
area when performing the measurements.
> Temperatures given on probes/sensors relate only to the
measuring range of the sensors. Do not expose handles and
feed lines to any temperatures in excess of 70 °C unless they
are expressly permitted for higher temperatures.
> Do not perform contact measurements on non-insulated, live
parts.
> Transport and store the instrument exclusively in the aluminium
case provided in order to avoid damage to the sensor.
> Do not store the product together with solvents. Do not use any
desiccants.
> Carry out only the maintenance and repair work on this
instrument that is described in the documentation. Follow the
prescribed steps exactly. Use only original spare parts from
Vito AG.
2.3. Protecting the environment
> Dispose of faulty rechargeable batteries/spent batteries in
accordance with the valid legal specifications.
> At the end of its useful life, send the product to the separate
collection for electric and electronic devices (observe local
regulations) or return the product to Vito AG for disposal.

3.1. Use
The OILTESTER is a handy measuring instrument for the fast
inspection of deep-frying oils and is designed in equal measure for
left and right handers.
The TPM value (total polar materials) enables a statement on the
ageing of deep-frying oils due to the effects of heat.
The following measuring tasks can be performed:
• Display temperature of the deep-frying oil:
Indicator for correct setting of the deep-fryer, inspection of
integrated temperature displays.
• Display TPM value:
Indicator for the ageing of the deep-frying oil.
The sensor works on a capacitive basis and determines the total
amount of polar materials in % as the reading.
The free fatty acids that are determined above all for the evaluation
of unloaded oils (rancidity) cannot be detected.
The temperature of the deep-frying oil to be measured must
be at least 40 °C. The maximum operating temperature is
200 °C.
The sensor and the probe tube are designed to come into
contact with oil used in deep fat fryers for the typical
duration of a spot check measurement. The materials used
in these components meet the relevant requirements in the
Regulation (EC)1935/2004.
