SVANTEK 977W User Manual
<Start/Stop> push-button working mode selection
In the
Start/Stop
position the user can choose between
Direct
and
With Shift
. When the
Direct
option is selected, the instrument reacts on each
of the
<Start/Stop>
push-button press, starting or stopping the
measurements.
When the
With Shift
option is selected the
<Start/Stop>
push-button
operates at the same time or in a sequence with
<Shift>
. The measurements
are started or stopped after pressing both push-buttons.
8.7. Setting parameters of the I/O port - Multifunction I/O
The
Multifunction I/O
enables the user to
select the available functionality of the
I/O
port (3.5 mm jack socket).
<ENT>
Note: If the RPM function is switched on (path: <Menu> /
Measurement / RPM Measurement) the Multifunction I/O is set
automatically on Digital In mode and with Ext.Trigger function.
The
I/O
jack socket can be used as:
the output of the analogue signal (
Analog Out
) transmitted from the input
of the instrument to its output without any digital processing (i.e. frequency
filtering),
the input of the digital signal used as an external trigger to start the
measurements (
Digital In
). The instrument is acting in this case as so
called “slave instrument”,
the digital output (
Digital Out
) used for triggering other “slave
instrument(s)” (the instrument is acting in this case as a “master
instrument”), or as a source of any alarm signal in case of certain
circumstances occurred during the measurements (i.e. the level of the input
signal was higher than a user selected trigger alarm setting).
The more detailed description of the
I/O
socket is given in App. C.
►
Slope parameter for the Digital In mode (Ext.Trigger function)
In case of
Digital In
the signal appeared on the
I/O
socket will be be treated
as the external trigger if
External
is chosen as a trigger (
path: <Menu> /
Measurement / Measurement Trigger / Trigger: External
). For the
Digital In
mode only the
Ext.Trigger
value is available for the parameter
Function
. It is
possible to set up
Slope
as positive
[+]
or negative
[-]
by means of the
◄ or
► push-buttons.
