1. Basic safety instructions
Please read through the following safety instructions carefully:
Avoiding electricity:
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 safety:
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 177-4
The probe sockets in testo 177-4 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.

5. Mounting
5.1 Mounting the wall holder
Mounting materials (e.g. screws, dowels) are not included.
1 Position the wall holder at the required location.
2 Using a pencil or similar, mark where the fixing screw is to go.
3 Prepare the area for mounting (e.g. drill a hole, put in dowel).
4 Mount the wall holder using a screw which fits.
5.2 Securing the data logger with a lock
1 Insert the data logger into the wall holder.
2 Place the retainer key in the wall holder.
3 Attach the lock to the wall holder (Accessory: Part no.
0554 1755).
12
5.3 Transportable unit
A unit can be made out of the wall holder, logger and the
interface to make transport or dispatch easier.
1 Push the data logger into the wall holder.
2 Push the interface onto the wall holder.
3 Secure the unit by connecting the wall holder and the interface
using the screw supplied.
Warning!
6. Connecting probes/switch
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 177-T3:
Use the enclosed twin-wire cable to connect the switch (door
contact). Connect a potential-free button or switch to it.
False connection!
Electric shock! Damage to data logger!
Do not apply electrical signal to cable and avoid contact with live parts.
Only one potential-free contact should be connected.

7. Programming
7.1 Installing software
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 data logger to PC, P. 14 once
the software is successfully installed.
7.2 Connecting data logger to PC
You will need a free serial interface (RS232) or a USB interface
to connect the data logger interface to your PC.
Proceed with Step 1 if using a serial interface.
The USB driver must already be installed in the PC when
using a USB interface. The driver and installation instructions
are enclosed with the USB interface. Proceed with Step 1
once successfully installed.
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.
5 Start the testo ComSoft software.

The readings saved in the data logger are not transmitted to
the PC when the connection is opened. Carry out the following
to transmit the readings:
Click twice on the title of the protocol (See testo ComSoft
software instruction manual).
Use one connection for several data loggers
You can connect different data loggers once a connection has
been set up. The connection must be closed when changing
the data logger and then opened again for the new data
logger. Otherwise, it cannot be identified by the software (See
7.6 Closing the connection, P.24).

8. Reading out data
You have three options to read out data from the data logger:
1. Via testo ComSoft software. Data is transmitted directly to a
PC.
Please read the Instruction manual on the testo ComSoft
software.
testo ComSoft software is available in 2 versions with the
following range of functions:
testo ComSoft 3 Basic (0554.1758)
- Programming and reading out the testo 174,
testo 175 and testo 177 data loggers
- Display and printout as table or diagram
- Data export (e.g. in Microsoft Excel)
- Automatic search for instrument driver when started
(Auto Detect)
testo ComSoft 3 Professional (0554.0830)
like testo ComSoft 3 Basic, but with the following additional
features:
- Programming and reading out other Testo instruments such
as testo 400, testo 650, etc.
- Display and printout as number box, histogram, form, analog
instrument, parametric graph
- Data management function
- Analysis functions (compensation curve, mean function)
- Selection of different printing heads for table and graph
printouts
- Adaptation of menus and range of functions
- Developer ToolBox with functions to incorporate the instrument
driver in non-Testo software
2. Via the testo 580 data collector.
Data can then be read out via testo Comsoft software.
For more information, refer to the testo 580 Instruction
manual.
3. Printout via testo 575 fast printer
For more information, refer to the testo 575 Instruction
manual.

9. Changing the battery
1 Please read out the saved data before changing the battery.
See testo ComSoft software Instruction manual
If it is not possible to read out the saved data due to low
battery capacity, please carry out the following:
2 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. Accessories/Spare parts, 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. Technical data
11.6 Battery life
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.
