SVANTEK 974 User Manual

1. INTRODUCTION

The SVAN 974 is an all-digital Vibration level meter (VLM) as well as a real

time 1/1 or 1/3 octave and FFT analyser. The instrument is designed for

general vibration measurements, industrial machinery monitoring,

occupational health and safety monitoring. The accelerometer input supports

differenttypesofvibration sensors, includingIEPE,Charge and Direct. Parallel

to the vibration measurement, the RPM measurement with dedicated

tachometer can be performed.

Three vibration user configurable profiles allow parallel measurements with

independently defined frequency filters and RMS detector time constants.

Each profile provides significant number of results (like RMS,Ovl,Peak,P-P

and MTVV). Advanced time history logging for each profile provides complete

information about the measured signal using the SD-card fitted in the bottom

of the meter and can be easy downloaded to any PC using the USB interface

and SvanPC++ software.

All required weightingfilters: HP1,HP3,HP10,Vel1,Vel3,Vel10,VelMF,Dil1,

Dil3,Dil10 and Wh for general vibration measurements (like acceleration,

velocity and displacement), including the latest ISO 20816-1:2016 standard,

are available with this instrument.

Using the computational power of its digital signal processor the SVAN 974

instrument can, simultaneously to the meter mode, perform the real time

1/1 Octave or 1/3 Octave analysis including calculations of statistical levels.

Time domainwaveform signal recording on theSD-card is available asan option and advanced trigger and alarm

functions are available in the standard version of this instrument.

A fast USB 1.1 interface (12 MHz) creates a real-time link for the PC "front-end" application of the SVAN 974

instrument. The measurement results can be downloaded to PC using all the interfaces mentioned above.

The instrument is powered from four AA standard alkaline or rechargeable batteries (i.e. NiMH –a separate

charger is required) or from the USB interface. Robust and lightweight design enhances the exceptional features

of this instrument.

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 Control push-buttons on the front panel

The following control push-buttons are located on the front panel of the

instrument:

•<ENTER>,<Menu>,<Save>,

•<ESC>, <Cal.>,<S/P>,

•<Shift>, [Markers]

•<Alt>, [Markers]

•▲, ▼, ◄, ►

•<Start/Stop>.

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.

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.

SVANTEK 974 User Manual

<Menu>

This push-button (<ENTER> pressed together with <Shift>) enables the user to enter

the main list containing seven sub-lists: Function, Measurement, Display, File,

Instrument and Auxiliary Setup. Each of the above-mentioned menu lists consists of

sub-lists, elements and data windows. These main sub-lists will be described in detail in

the following chapters of the manual. Double pressing the <Menu> push-button enters

a list containing the last eight opened sub-lists. It often speeds up the control of the

instrument as the user has faster access to the most frequently used sub-lists for easy

navigation.

<Save>

This push-button (<ENTER> pressed together with <Alt>) enables the user to save the

measurement results (see description in chapter 3.5).

<ESC>

This push-button closes the control lists, sub-lists or windows. It acts in an opposite way

to the <ENTER> push-button. When the window is closed after pressing the <ESC>

push-button, any changes made in it are ignored in almost all cases.

<Cal.>

This push-button (<ESC> pressed together with <Shift>) opens the Calibration sub-

list.

<S/P>

This push-button (<ESC> pressed together with <Alt>) enables the user to pause or

break the measurement process temporarily during the measurement or to save the

setup file if the instrument is not running the measurement.

◄, ►

These push-buttons enable the user specifically to:

•select the column in a multi column parameter list;

•select the parameters value in an active position (e.g. Start Delay period: 1s, 2s, 3s,

… etc.);

•control the cursor in Spectrum and Logger modes of result presentation;

•select the position of the character in the text editing screen;

•activate markers 2 and 3;

•speed up changing the numerical values of the parameters when pressed and held.

(◄, ►)

The ◄or ► push-buttons pressed together with <Shift> enable the user specifically to:

•change the parameters value with double step (e.g. Start Delay period: form 1s to

11s, 21s, … etc.);

•to shift cursor from the first to the last position and back on the graphical view mode.

[◄, ►]

The ◄or ► push-buttons pressed together with <Alt> enable the user specifically to:

•select the parameters value in an active position in the matrix parameter list;

•scroll the parameters in an active field on the result view screen;

•insert or delete a character in the text edition screen.

▲, ▼

These push-buttons enable the user specifically to:

•select line in the list;

•select the active field on the result view screen;

•select the correct character from the list in the text edition screen;

•activate markers 1 and 4.

(▲,▼)

The ▲ or ▼ push-buttons pressed together with <Shift> enable the user specifically to:

•shift the cursor from the first to the last position and back on the menu list;

•change the relationship between the Y-axis and X-axis of all plots presented on the

screen.

[▲, ▼]

The ▲ or ▼ push-buttons pressed together with <Alt> enable the user specifically to:

•change the mode of result presentation;

•programme the Real-Time Clock (RTC) and Timer.

SVANTEK 974 User Manual

[Info]

The <Info> push-button (simultaneous pressing the ◄

and ► push-buttons) opens the window with the help

information in the measurement display modes. Press

<ESC> or <ENTER> to exit the Info screen.

The <Markers> push-button (<Alt> pressed together with <Shift>) enables the user to

mark special events, which occurred during the performed measurements. To activate

the markers, the logger should be switched on (path: <Menu> / Measurement / Logging

/ Logger Setup) and one or more logger results (Peak, P–P, Max, RMS) in profiles have

to be activated (path: <Menu> / Measurement / Logging / Logger Results).

To enter the marker mode, the user must press <Shift> and <Alt> push-buttons

simultaneously duringthe measurement.Thenfour available markers appear on

the screen. To switch on marker number 1 the user must press ▲push button

(number 2 - ◄, number 3 - ►and number 4 - ▼). Active marker number will be

highlighted. To switch off the marker the user should press the appropriate

arrow-button second time.

The markers disappear from the screen after pressing <Shift> and <Alt>, but

the status of markers doesn’t change. To continue working with the markers, the

user should press <Shift> and <Alt> again.

The current state of the markers is indicated in the logger file (cf. App. B for

details) and can be used to show them with the help of the dedicated

presentation software.

An example presentation of the markers on the time history plot is shown below

(to view a plot with markers the user should transfer data to the appropriate

software such as SvanPC++).
