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 deliv-
ery is complete and undamaged.
6.1 Measuring
Connect one or more probes to the measuring instru-
ment.
Irrespective of which sockets are assigned the meas-
uring 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 sec-
onds 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 dis-
played in the top line. “P inactive” means that a
measuring program was not activated (refer to Chap-
ter 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.
