Please read through the following safety instructions carefully:

Avoiding eelectricity:

Never use the instrument and external probes to measure on or near live parts if the instrument is not
expressly approved for current and voltage measurement!

Product ssafety:

Prior to each measurement, check if the connections are connected properly via the blind plug and if
the right probe is correctly inserted. Otherwise the protection class specified in the Technical data
cannot be guaranteed.

The logger should only be operated within the parameters specified in the Technical data.

Please handle the logger with care.

The instrument should only be opened if expressly described in the instruction manual for
maintenance purposes.

Force should never be applied!

Only for testo 175-T3

The probe sockets in testo 175-T3 are not isolated from one another. Please take note of this when
using surface probes with a non-insulate thermocouple.

Disposal:

Please dispose of spent batteries responsibly.

You can return your logger directly to us at the end of its service life. We will dispose of it responsibly.

Due to technical reasons, the display speed of the liquid crystals
slows down at temperatures below 0 °C

(approx. 2 s at -10 °C, approx. 6 s at -20 °C). However, this
does not have any influence on the accuracy of the

Observe the following points when connecting the probes to the
data logger and to the measurement points:

Observe poles of plug.

Insert the plugs firmly into the connections to guarantee that
they are properly in place. Force should not be used.

Ensure that the plugs are firmly attached to the data logger or
that the connections are in place with a blind plug.

Ensure that the probe is positioned properly to avoid disturbing
influences on the measurement.

testo 175-T3

:

Ensure that each respective configured probe is connected to
the socket (via testo ComSoft software). The numbers of the
connections are printed on the housing!

testo 175-S1/S2

:

The testo 175-S1/S2 data logger is designed for use in electric
circuits in measurement technology, automatic control, information
technology in process, laboratory and technical systems (0 to
20mA current loop; 0-1V, 0-10V voltage sockets).

Connect the cables by following the printed connection plan.

Warning!

Strong currents and high voltage!

Electric sshock!

The

testo 175-S1 and testo 175-S2 data logger should only be connected to electric

circuits from the SELV (safety extra-low voltage) or PELV (protective extra-low voltage)
category.

The testo 175-S1 and testo 175-S2 data logger should only be connected to direct
current circuits.Rated voltage should only be max. 60 V DC.

The electric circuits in the data logger should only be set up, connected, operated
and maintained by trained personnel.

Disconnect the measurement leads from the logger before changing the battery.

7.1 IInstalling ssoftware

In order to program your data logger in accordance with your
individual needs, you will need a PC on which the testo ComSoft
software is installed.

You will find instructions on the installation and operation of the
software in the testo ComSoft instruction manual.

Continue with

7.2 Connecting ddata llogger tto PPC

, P. 14 once the

software is successfully installed.

7.2 CConnecting ddata llogger tto PPC

You will need a free serial interface (RS232) or a USB interface to
connect the data logger interface to your PC.

1

Connect the serial connection cable or USB connection cable
of the interface to your PC.

2

Connect the interface to the connection cable.

3

Insert the interface in the desk-top holder.

4

Place the logger in the desk-top holder.

The interface can be placed directly in the wall holder. In this
way, the data can be read out directly on location.

Ensure that the interface is completely plugged on and snapped
into place. Otherwise the connection is not guaranteed.

Remove the screw at the back of the data logger using a small
crosstip screwdriver.

3

Using a screwdriver, lift the back wall at the bottom of the data
logger and then remove from data logger 1.

4

Attach the jumper (included with spare battery) to the plug
connector beside the connection for the battery 2.

The inserted jumper prevents the memory from being deleted or
written over.

5

Take the battery out of the battery compartment and pull out the
plug-in connection to the data logger 3.

6

Connect the new battery to the data logger`s plug-in connection
and place in battery compartment.

Only original Testo spare batteries should be used
(see

12. AAccessories/Spare pparts

, P. 34 for Part nos).

7

Remove the jumper from the plug connector.

8

Hold the back wall at a 45° angle to the top of the instrument
and then flip down.

Ensure that both O rings are positioned on the screw so as to
guarantee that it is sealed completely.

9

Press the back wall onto the logger with your thumbs. Make
sure that it is closed properly 4 and then secure using screw.

10

Place the data logger in the desk-top holder and attach to
interface.

11

Start the testo ComSoft software and set up a connection to the
data logger by clicking twice on the required connection with the
left mouse button.

- The

New battery

window is opened 5.

Enter the date of battery change.
Enter the temperature range in which you will be using the
data logger and confirm with OK.

- The data logger is now ready for use.

11.7 BBattery llife

Typical approximate values for the expected battery life are included
in the programming windows of the software. These values are
calculated on the basis of the following factors:

- Measuring rate

- Number of probes connected

- Status led (green LED) activated/deactivated

The calculated data is only an approximation since the battery life
depends on many additional factors.

The following factors have a negative influence on the battery life:

- Alarm LED flashing for longer periods of time

- Frequent reading out (several times a day)

- Strong fluctuations in operating temperature

The following factors have a positive influence on the battery life:

- Deactivated Status led (green LED) particularly in the case
of extended measuring rates

The battery capacity displayed is based on calculated values.
The data logger can be switched off if a critical power level has
been reached. The following could occur:

- The logger continues to take readings although the display

indicates that the battery capacity is “empty”.

- The measuring program is stopped even though the battery
capacity display indicated a short time previously that
battery capacity was available.

Saved readings are not lost if the battery is spent or
changed. Requirement:
The battery is changed by following the directions in the
Instruction manual.
