2 Safety and the environment
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.
> Never use the instrument to measure on or near live
parts.
> Before each measurement check that the connections
are correctly closed with blanking plugs or that
appropriate sensors have been correctly plugged in.
The protection class in the technical data specified for
the corresponding instrument may otherwise not be
reached.
> testo 175 T3 : The maximum permissible difference in
potential between the sensor inputs is 50 V. Take this
into account when using surface sensors with non-
isolated thermocouple.
> 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.
> 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.
> 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.
> Do not use the device in a polluted environment
(heavily dusty, oil, foreign matter, volatile chemicals).
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
Testo for disposal.
