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.
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
Data loggers testo 175 are used to store and to read out
individual readings and measurement series.
With testo 175 measurement values are measured, saved
and transmitted to the PC via USB cable or SD card,
where they can be read out and analysed with the software
testo Comfort Software. With the software the data loggers
can also be individually programmed.
Typical applications
testo 175 T1 and testo 175 T2 are optimally suitable for
temperature measurements in refrigerators, freezers, cold-
storage rooms and cooling shelves.
testo 175 T3 records two temperatures at the same time
and is most suitable e.g. for monitoring the temperature
spreading between feed and return flow in a heating
system.
testo 175 H1 controls the climatic conditions e.g. in
warehouses, offices and in the production area.

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
Shop for Data Logging products online at: www.DataLoggerStore.com 1.888.610.7664

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.
4First steps
4.1. Unlock the data logger
1. Open the lock with the key (1).
2. Remove the lock (2) from the locking pin.
3. Pull the locking pin (3) out of the holes in the wall
bracket.
4. Slide the data logger out of the wall bracket (4).

4.2. Inserting batteries
In order to reach the battery life under application
temperatures below -10 °C you should use
Energizer L92 AAA-size cells.
1. Place the data logger on its front.
2. Loosen the screws on the back of the data logger.
3. Remove the battery compartment cover.
4. Insert the batteries (type AAA). Observe the polarity!
5. Place the battery compartment cover on the battery
compartment.
6. Tighten the screws.
- The display shows rST.
4.3. Connecting the data logger to
PC

The software is available in the Internet as a free download
requiring registration: www.testo.com/download-center.
The instructions for the installation and operation
of the software can be found in the testo Comfort
Software Basic 5 instruction manual, which can be
downloaded together with the software.
The software can be ordered on CD (article-no:
0572 0580), if the download from the Internet is
not desired.
For testo Comfort Software Professional und testo Comfort
Software CFR:
> Insert the CD into the CD-ROM drive.
1. Install the software testo Comfort Software.
2. Connect the USB cable to a free USB port on the PC.

instructions testo Comfort Software.
5Display and control
elements
5.1. Display
The display function can be switched on/off via the
software testo Comfort Software.
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
page 20.
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.
