SVANTEK 974 User Manual
2. MANUAL CONTROL OF THE INSTRUMENT
Control of the instrument has been developed in a fully interactive manner. The user can operate the instrument
by selecting the appropriate position from the selected
Menu
list. Thanks to that, the number of push-buttons for
control of the instrument has been reduced to nine for ease of use and convenience.
2.1

The name given in (...) brackets denotes the second push-button function which
is available after pressing it in conjunction (or in sequence) with the
<Shift>
push-button. For the first two push-buttons the name given in square brackets
[…] denotes also the third push-button function which is available after pressing
it in conjunction (or in sequence) with the
<Alt>
push-button.
<Shift>
The second function of a push-button (written in red colour on a push-button) can be
used when the
<Shift>
push-button is pressed. This push-button can be used in two
different ways:
•
as
Shift
like with a computer keyboard (e.g. while typing the filename); both
<Shift>
and the second push-button must be pressed together (two finger
operation);
•
as
2nd Fun
; this push-button can be pressed and released before pressing the
second one or pressed in parallel (while operating in
“2nd Fun”
mode, see the
following notice) with the second push-button (one finger operation).
The
<Shift>
push-button pressed in conjunction with
<Alt>
enables the user to activate
the
Markers
on the plots during the measurement.
<Alt>
This push-button enables the user to choose the third push-button function in case of
[<Save>]
and
[<Pause>]
push-buttons. To select the third function, the user must press
the
<Alt>
and the second push-button simultaneously.
Note: Simultaneously pressing the <Alt> and <Start/Stop> push-buttons switches the instrument on
or off.
<Start/Stop>
This push-button enables the user to start the measurement process when the
instrument is not measuring or to stop it when the instrument is in course of the
measurement. It is also possible to set the mode of this push-button such that to start or
stop the measurements the user should press it simultaneously with the
<Shift>
push-
button. This can prevent accidentally starting or stopping a measurement at the wrong
time by just brushing against the Start/Stop button on its own.
Note: Changing the <Start/Stop> push-button mode is performed in the Keyboard Settings window
of the Instrument list (see description of the Instrument list).
<ENTER>
This push-button enables the user to enter the selected position shown on the screen
Menu list or to confirm selected settings. Some additional functions of this push-button
will be described in the following chapters of this manual.
