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 176 T3 testo 176 T4: 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.
> 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.
> 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.

3.1. Use
The data loggers testo 176 serves the purpose of saving and
reading out individual readings and measurement series.
Readings are measured and saved with testo 176 and transferred
to the PC via USB-cable or SD-card, where they can be read out
and evaluated with the help of the testo Comfort Software. With the
software the data loggers can also be individually programmed.
Typical applications
testo 176 T1 is optimally suitable for temperature measurements
under extreme conditions, like e.g. on ships or in power plants,
because its metal housing provides excellent protection against
mechanical influences.
Due to the possibility of connecting external, high-precision Pt100
sensors the testo 176 T2 is optimally suitable for temperature
measurements, e.g. in food applications or in the laboratory.
With its external sensor connections (thermocouples type T, type K
and type J) and its robust metal housing the testo 176 T3 is able to
perform parallel temperature measurements on up to four
measuring locations under extreme conditions.
The external sensor connections (thermocouples type T, type K
and type J) make the testo 176 T4 and excellent choice for different
applications, such as e.g. simultaneous feed and return
temperature measurement in underfloor heating at up to four
measuring locations.
The testo 176 H1 is optimally suitable for parallel temperature and
humidity monitoring, e.g. in warehouses.
With its external sensor connections and its robust metal housing
the testo 176 H2 is able to execute temperature and humidity
measurements in parallel mode under extreme conditions.
The testo 176 P1 is able to measure pressure, temperature and
humidity at the same time and is thus optimally suitable for the
documentation of ambient conditions, e.g. in laboratories.

Battery life
The programming windows of the software provide you with typical
guide values for the expected lifetime of the battery. This lifetime is
calculated on the basis of the following factors:
• Measuring cycle
• Number of connected sensors
Since the battery life depends on quite a few other factors, the
calculated data can only serve as guide values.
The following factors have a negative effect on the battery life:
• longer flashing of the LEDs
• frequent reading out (several times per day) via the SD-card
• extreme fluctuations in operating temperature
The following factors have a positive effect on the battery life:
• display switched off
The battery capacity reading in the display of the data logger is
based on the calculated values. However, the data logger is
switched off when a critical voltage level has been reached. It may
therefore happen that:
• readings are still recorded, even though the battery capacity
reading says "empty".
• the measurement program is stopped, even though the battery
capacity reading just before indicated a still remaining battery
capacity.
In case of an empty battery or a battery change saved readings will
not be lost.

5.1. Display
The data loggers testo 176 T1, testo 176 T3, testo 176 H2

The display function can be switched on/off via the testo

Depending on the operating status, various information may
be shown in the display. A detailed representation of the
information that can be called up can be found under Menu
overview.
For technical reasons the display speed of liquid crystal
displays becomes slower at temperatures below 0 °C
(approx. 2 seconds at -10 °C, approx. 6 seconds at -20
°C).
This has no influence on the measuring accuracy.
