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.

4.1 Display
The display function can be activated/deactivated via the testo
ComSoft software. The testo 177-T1 data logger do not have
a display.
testo 177-T2:
testo 177-T3,testo 177-T4, testo 177-H1:
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
measurement.

4.3 Display sequence
Depending on the mode, different information can be displayed in
the data loggers with display. You will find a detailed description of
the information which can be called up in the short version of the
instruction manual enclosed with every data logger.
4.4 Button functions
In all modes in data loggers with display:
Press the button to switch between the displays.
Press the GO button to activate an intermediate measurement.
Wait mode and Key start start criterion programmed:
Press the GO button for approx. 3 s to start the measuring
program.
- The measuring program starts, Record appears in the display
(if available) and the Status led flashes five times.
Record mode:
Press the GO button for approx. 3 s to set a time mark.
- The Status led flashes five times.
Time mark: This function enables you to monitor and read
out/print out the memory content from a specified point in time
( time mark ) without having to reprogram the data logger. The
readings from Start ( All readings ) are also saved.
The readings from Start ( All readings ) or From time mark can be
read out on the testo 575 fast printer or the testo ComSoft
software.
The readings from Start ( All readings ) can be read out on the
testo 580 data collector.
Only one time mark can be set. If the GO button is pressed for
approx. 3 seconds in the Record mode, the existing time mark
is deleted and a new time mark is set up.
- The readings (max./min. values, exceeding of alarm values)
are shown in the display (if available) from the set time mark.

5. Mounting
12
5.1 Mounting the wall holder
Mounting materials (e.g. screws, dowels) are not included.
1Position the wall holder at the required location.
2Using a pencil or similar, mark where the fixing screw is to go.
3Prepare the area for mounting (e.g. drill a hole, put in dowel).
4Mount the wall holder using a screw which fits.
5.2 Securing the data logger with a lock
1Insert the data logger into the wall holder.
2Place the retainer key in the wall holder.
3Attach the lock to the wall holder (Accessory: Part no.
0554 1755).
5.3 Transportable unit
A unit can be made out of the wall holder, logger and the
interface to make transport or dispatch easier.
1Push the data logger into the wall holder.
2Push the interface onto the wall holder.
3Secure the unit by connecting the wall holder and the interface
using the screw supplied.

6. Connecting probes/switch
13
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.
Measuring rate is activated if the contact is open electrically i.e. if
both cables are not connected with one another.
Measuring rate Door if the contact is closed electrically i.e. if both
cables are connected with one another (See page 24).
The data logger requires slightly more energy if the contact is
electrically closed. It is recommended to select the contact so
that it is electrically open most of the time.
testo 177-T4:
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!
Warning!
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.
1Connect the serial connection cable or USB connection cable
of the interface to your PC.
2Connect the interface to the connection cable.
3Insert the interface in the desk-top holder.
4Place 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.
