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.
>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.
>Do not perform contact measurements on non-insulated, live
parts.
>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
Testo.
>Temperatures given on probes relate only to the measuring
range of the sensors. Do not expose handles and feed lines to
temperatures in excess of 40 °C (104 °F), unless they are
expressly permitted for higher temperatures.
>After the final measurement, allow probes and probe shafts to
cool down sufficiently in order to avoid burns from the hot
sensor tip or the probe shaft.
>Improper use of rechargeable batteries can lead to destruction
or injuries by means of current surges, fire or escaping
chemicals. The following instructions must be observed to avoid
such hazards:
•Only use in accordance with the directions in the instruction
manual.
•Do not short, take apart or modify.
•Do not expose to heavy impacts, water, fire or temperatures
above 60 °C.
•Do not store in the proximity of metal objects.
•Do not use leaky or damaged rechargeable batteries. In the
event of contact with battery acid: Thoroughly wash affected
area with water and consult a doctor, if necessary.

•Only charge in the instrument or the recommended charging
station.
•Immediately stop the charging process if this is not
completed in the given time.
•In the event of improper function or signs of overheating,
immediately remove the rechargeable battery from the
measuring instrument/charging station. Caution:
Rechargeable battery may be hot!
