testo 454 -The handy measuring instrument
Nearly all of the probes from the Testo range can be connected to the universal hand-held
instrument. The automatic probe recognition function facilitates quick control measurements. In air conditioning technology several parameters can be quickly measured on
location e.g. temperature, humidity, velocity and pressure. The probe designs are fully
adapted to the respective applications.
testo 454 - The powerful data logger
All of the boundary conditions for an independent long-term measurement are programmable: start of measurement, end of measurement, location name and alarm outputs are
determined by selectable starting criteria. The six freely assignable channels and three
measuring programs make the data logger very versatile. There are various additional special functions available for air conditioning and ventilation technology: averaging, volume
flow display, Pitot tube calculation etc.
testo 454 - Independent application
The rechargeable, environment friendly rechargeable battery makes the user independent
of the power supply. Power can also be supplied from a car battery.
testo 454 - User-friendly operation
The housing is ergonomic and ideal for practical operation and is made of robust ABS.
The large, illuminated display can be easily read and can display three different parameters. The menu-driven user operation via the sealed keyboard makes the instrument easy
to use.
testo 454 - Configuring and data processing on the PC
If a PC and the Comfort software are connected you can take full advantage of the benefits
offered by the data logger. All of the settings in the data logger are prepared first in the PC
and are then loaded into the data logger. Only the measurement is started on the measuring location. The processing of saved measured in the PC is just as uncomplicated as configuring.

Warning
Please read before using instrument
Do not measure on live parts.
Observe permissible storage and transport temperatures and the permissible oper-
ating temperature (e.g. protect measuring instrument from direct sunlight)!
Switch off the instrument when changing the configuration (e.g. probe change, plug-
ging in the V24 cable) because the values specific to the probes can only be read
after the instrument is switched on.
If the instrument is opened, improperly handled or force is used the warranty rights
are cancelled.
In the case of temperature probes which come into contact with metal, there may
be an electric discharge caused by the different potential between metal and the
surface probe. Please apply adhesive tape to the point of measurement during
this type of application. In this way a discharge which could limit the functioning
of the instrument is preventde.

6Introductory training
The purpose of the introductory training is to make
the operation of the instrument easier for you.
Measuring, printing and saving is explained in short,
easy steps.
The functions of the testo 454 are described in
detail in Chapter 8.
Before using the instrument please check if the delivery is complete and undamaged.
6.1 Measuring
Connect one or more probes to the measuring instrument.
Irrespective of which sockets are assigned the measuring instrument recognises which sockets are
assigned and which probes are connected.
It is important that the probes are connected
before the instrument is switched on so that the
instrument can query the probe codes when switched
on.
Now switch on the measuring instrument.
A short function test is conducted. After several seconds the instrument is in the measuring menu and
the first set of information appears in the display.
The code of the respective measuring program is displayed in the top line. “P inactive” means that a
measuring program was not activated (refer to Chapter 8.3.3)
The measured values are shown in the lines below:
• the socket assignment is shown in the left
column
• the measured value is in the middle column
• the unit is in the right column
If you happen to go to the wrong menu when going
through the steps or if you simply do not know how to
proceed press the <Arrow> key several times and
you will return to the next highest menu and back to
the measuring menu.

7Operating instructions
7.1 Measuring
When measuring the probes must be connected
before the instrument is switched on.
Insert one or more probe plugs into the data logger
socket(s). It does not matter which socket you
choose as the data logger recognises the assignment of the input channels and the probes connected.
Switch on the instrument.
A short function test is carried out.
The instrument then goes to the measuring menu.
A 4 line display appears.
The first line shows the program status, in this case
“P. inactive” for program inactive which means that a
measurement is not activated (activated programs
wait on the respective programmed starting criterion,
see Chapter 8.3.3).
The current measured values are shown in the following lines. The input channel (socket no.) is shown
in the left column while the current measured value is
shown in the right column.
Using <up>/<down> the measured values can be
scrolled up and down in the display (if more than 3
are active).
Leave the measuring menu by pressing <Enter> and
change to the main menu.
The main menu includes the following submenus:

8.3.3 Programs 1-3
Measurements can be controlled via 3 freely definable measuring/saving programs. The
channel, starting criteria, measuring rate, measurement duration or number of values are
defined in the programs 1-3. The programs are started once the “starting criterion” is fulfilled. The starting criterion is checked at the measuring rate: if a slow rate has been set it
is advisable to set a an intermediate rate when checking the starting criterion (see Chapter
8.6.5). All 3 programs can be started independently of each other, they save all of the connected probe values at the set measuring rate. “Programming 1” can be taken as an example for all 3 programmings.

8.3.3.1 Program starting criterion
Select a starting criterion:
External signal
The starting command is triggered when an external
voltage signal is input. Please use the lead
0554.0012 (See Ordering data) when inputting an
external voltage signal. In the case of a trigger circuit
the limit values of the trigger input must be adhered
to (Refer to Technical data). The trigger input in
testo 454 is electrically isolated from the other
circuit.
Time
The program start is made dependent on the date
and time. If the instrument is switched off the start is
delayed by approximately 5 seconds until the instrument has completed the function test and probe recognition.
Overrun
Saving begins when the measured value of a parameter, defined by you, overruns on a channel specified
by you. An intermediate rate is recommended to
check the starting criterion frequently (see Chap.
8.6.5).
Underrun
Saving begins when the measured value of a parameter, defined by you, underruns on a channel specified by you. An intermediate rate is recommended to
check the starting criterion frequently (see Chap.
8.6.5).
Gradient
The program is started once the measured value of a
specified parameter in the defined channel changes
quicker than that of the limit value defined by you.
The specified value refers to:
∆ t = 1 s
The display opposite means that
the program is started when the measured value
changes by more than 5 %RH in 1 second.
Difference
When the differential value (of a parameter) in two of
the channels specified by you is overrun measurement is started. If, for example, the temperature of
K1 is 50 °C below that of K2 the program is started.

Note on the differential trigger programming in
combined probes:
If combined probes are used for the starting criterion
“Difference” there is not enough space in line 3 of the
display to show clearly the channel and the parameter.
In the 3rd line of the display opposite only “K2”
appears at the end of the line. The parameter is allocated correctly by numbering the key confirmations
of <up> <down>.
The confirmation of a starting criterion via <Enter>
triggers a jump to the"PROGRAM RATE" parameter.

Note:
The program end criterion is delayed in relation

the program continues saving for a short time
even though the programmed limit value is no
longer overrun.

8.3.3.2 Rate
Specify the rate at which the measuring instrument
should save the probe data during this measurement.
Entries from 0.1 seconds to 24 hours are possible.
Seconds can be given in fractions. Minutes and hourly rates are usually whole numbers. All values are
saved according to the probes connected.

Please note that some measuring time must be
allowed for each connected probe since the sockets
must be serially checked.
The probe with the longest measuring time
defines the minimum measuring rate.

8.3.3.3 Activating duration and program
By confirming the input "PROGRAM RATE
"with <Enter>
you will go to the input mask "P
ROGRAM DURATION
".
You have 3 ways of defining the program duration:
1) as a time range (=“Duration”)
2) as a “# of values”
3) as an “Open End” measurement i.e. the measure-
ment runs until the memory is full or crashes.
If the trigger function refers to measured values, the
number of saved values can be lower than the number
of values programmed to be measured. Cause: the program running was prematurely interrupted because of
the following:
- a second activated program has been
started or
- the starting criterion for the current
program has not been fulfilled.
Confirm your entries with <Enter>.
To activate the program, switch the display
“activ.off” to “activ.on” via <up> <down>.
The program can be activated at any time.
When confirmed with <Enter> the measuring instrument takes over programming and goes back to the
"MEMORY" submenu.

8.6.3.1 Notes on battery operation
- In order to protect the instrument from total discharge when not operating connect it for one
day a month to the mains unit.
- If “Emergency” is displayed, a one-minute refresh cylce takes place which regenerates the
run down rechargeable battery. The red LED lights up in the battery charger. If the cycle has been
successfully completed “Charge quickly” appears in the display. If the refresher impulse was
insufficient the procedure can be repeated by switching the mains unit on and off with the instrument switched off. If the instrument does not go into the fast recharging mode the rechargeable
battery is defect. In order that the complete battery capacity is available the recharging cycle
should be repeated 2 - 3 times following total discharge.
- A recharging cycle takes approx. three hours and is displayed by the instrument by going from
“Quick” to “Conserve”. The compensation charge fills the rechargeable battery completely.
- The charge is active if testo 454 if switched off and the mains unit is connected or if the mains
unit is connected when the instrument is switched off.
- If the mains unit is plugged out during rapid recharging the instrument deactivates itself within one
second. Deactivation can take two minutes in the conservation mode.
- Long-term measurements should be started with a newly charged battery.
- The capacity of the rechargeable battery is correctly displayed in the instrument menu 4 hours
after charging.
- The operating limits of the rechargeable battery are shown with ”LowBat” or ”TempOut”.
8.6.3.2 Examples of the service life of testo 454
The service life depends on the probe assignment and the measuring rate. The following is a list of
typical examples which influence the service life of the rechargeable battery.

8.6.4 Auto-Off
The instrument automatically switches off after 10
minutes when not used if the Auto-off function is on.
This helps to save the batteries and hence the
environment. Key confirmations, serial communication, measuring programs with a measuring rate of
less than one minute which have been already started keep the instrument “awake” and it is not switched
off automatically.
Note: Activated measuring programs (P1 – P3) which
take the measured values as a basis for the starting
criteria are only executed if the intermediate rate and
the measuring rate are set at longer than 1 minute.
For rates less than 60 seconds the instrument should
stay switched on in order to start the measuring program. The Auto-Off should then be deactivated.
Make sure to switch off the instrument when you
are not using it and the auto-off function is off.
8.6.5 Intermediate rate
Indicate the time intervals within which the measuring
instrument has to check the conditions for a measurement (program start at overrun or underrun of
measured value or gradient). If you do not activate
this input the instrument only checks the conditions if
switched on or if the running program is at the set
measuring rate. This input is valid for all programs
and alarms.
Note: Intermediate rates in the seconds range are
not possible if the measuring rate is > 50 min i.e. the
minimum intermediate rate is 1 min.

Select an alarm criterion:
Overrun
The alarm is triggered when the parameter measured
value, defined by you, overruns on a specified channel. An intermediate rate is recommended to check
the alarm criterion frequently (see Chapter 8.6.5).
Underrun
The alarm is triggered when the parameter measured
value, defined by you, underruns on a specified
channel. An intermediate rate is recommended to
check the alarm criterion frequently (see Chapter
8.6.5)
Gradient
The alarm is triggered once the measured value of a
specified parameter in the defined channel changes
quicker than that of the limit value defined by you.
The specified value refers to::
∆ t = 1 s
Difference
When a differential value (of a parameter) in two of
the channels specified by you has been overrun the
alarm is triggered.

8.8.1 Special functions display
Special functions, calculated from the measured values of the connected probes, are displayed in the
measuring menu if they are activated in the
“S
PECIALS.” menu.
td = Dew point (Combination probes %RH - °C)

/h = Volume flow (Velocity probe)
The accuracy of the volume flow display
follows from the accuracy of the velocity
measurement. Multiply the maximum and
minimum possible velocity value in the
accuracy data by the cross-section to get the
permissible deviation of the volume flow
measurement.
m/s = Air velocity (pressure probe)
The Pitot tube differential pressure is
converted to air velocity. Here the air density
is entered as a parameter (see Appendix
“Probe description”).
Switching on or off is carried out via <up><down>
and your entry is confirmed via <Enter>.
The special functions selected are activated by a
restart. The settings remain even after the measuring
instrument is switched off.
8.8.2 Flow volume
Enter the dimensions of the air channel (round,
square, cross-section area). The measuring instrument calculates the flow volume set in
“SF
DISPLAY”(see above).
8.8.3 Density
The density is required for the conversion of the
dynamic pressure into velocity. Please find the corresponding value in the enclosure Measuring engi-
neering.
8.8.4 Pressure
The air pressure is required for the compensation of
the CO
2
probe and the pressure probe (Pitot tube).
Refer to the more detailed description in the enclosure Measuring engineering.

Cause: The measuring rate selected with the pro-
gram cannot be reached with the given
probe constellation.
Remedy: - Check min. rate
- Remove any unnecessary probes
- Slow down measuring rate
- Restart
Cause: The measured value memory is either full
or blocked because a measuring protocol
is being displayed or printed.
Remedy: - Quit the running program
- Quit “M
EMORY
-VIEW”
- Wait for printing or quit “P
RINT”
Cause: The program running cannot be changed.
Remedy: Quit program and restart.
Cause: The entered program start criterion can-
not be fulfilled:
- Starting time in the past
- Competing trigger criteria on the same
measuring channel.
Remedy: Correct entries for correctness and
change if necessary e.g.
- incorrect (past) time marks
- Difference trigger when only one probe
is assigned.
Cause: No recognisable probes connected
