the viscometer.
Insert the horizontal rod of the viscometer (E) into the nut (F).
Fig. 5 Set-up for the viscometer base
The viscometer should be placed on a stable surface free of vibrations (i.e. caused by other
machines or equipment). Do not put the viscometer in direct contact with sunlight or in the
middle of any air flow (the temperature of the sample can be easily influenced by the
surrounding conditions). The viscometer is designed for indoor use.
Use the height adjustment knobs until the height of the viscometer (located in rod E) is
correctly adjusted.
Plug the power cable into the connector located on the back of the equipment (Fig. 3
position 5) and plug it into the power source.
WARNING:
The socket by which the viscometer will be connected should have a ground. Always use
a power cable with a ground connection! Verify that the voltage and the frequency
coincide with the specifications for the viscometer (look at the identification label Fig. 4,
for more information). Before turning on the machine, let it sit for some time so that it
acclimates to the surrounding temperature in order to avoid a short-circuit caused by
condensation. The fluctuations of the power source should not surpass 10% of the
nominal voltage.
7.2 The keyboard and screen
Before starting up the machine, it is recommended to become familiar with the viscometer controls
seen in the previous section. The instrument has a 12 key keyboard (number 2 Fig. 2) and a colour

In the case of a successful check, the main menu will be displayed.
8. Menu system
8.1 The Main Menu
Fungilab viscometers work with a system of menus that allow the user to go through the instrument
in a quick and simple way. The basic actions in the menus are: moving through the options (‘’ and
‘’ keys), selecting an option (‘ENTER’ key) or returning to the previous menu (‘MEM/CLEAR’ key).

EVO EXPERT Manual 14/105
The main menu is the one that appears after the AUTOTEST screen. It is accessed by turning on
the machine normally and after a satisfactory result from the test run.
The main menu screen will show:
The menu can be navigated with the ‘’ and ‘’ keys. The current selection will be highlighted and
by pressing ‘ENTER’ you will access to the selected submenu (for more information about each
function in particular see the corresponding sections).
The first time the machine is used, it is advisable to access the ‘INSTRUMENT SETUP’ option as the
first step in order to establish the values for certain parameters of the viscometer such as language
and measurement units.
In the following sections, each of the 5 submenus of the main menu can be seen beginning with the
configuration submenu.

temperature, returning back to the previously used settings.
8.2.3 Density. (Default density change submenu)
The value assigned to the density of the fluid being measured can be changed by means of this
submenu. By default we consider the density of water as a reference point, but you can select any
other value. The default units will be g/cm3 of the Centimetre-gram-second system of units (CGS).
The field of the whole numbers appears highlighted in light blue background, which means that it
can be edited. Use the numerical keyboard to introduce the value desired for the density whole
numbers.
Once the digits of the whole numbers are introduced, press ‘ENTER’ to skip to the next field. Then,
the field of the decimal numbers will appear highlighted indicating that this field can be modified.
Use the numerical keyboard to introduce the decimal numbers of the density and press ‘ENTER’ to
save these numbers. In order to save the value of the density press ‘ENTER’ with the ‘SAVE’ option
highlighted in light blue background. The viscometer will return to the ‘Instrument setup’ menu.
NOTE: If you modify the density, the viscometer will give its measurements in
cSt (centiStokes), whereas if you conserve the initial density (considered the
density by default), the measurements will be in cP (centipoises), P (Poise) or
mPa·s, Pa·s.

EVO EXPERT Manual 17/105
8.2.4 Calibration (Calibration submenu)
This submenu contains the viscosity and temperature calibration options that the user can exploit to
recalibrate the viscometer. Moreover, it also contains the ‘RESET’ option to restore the factory-stage
calibration and erase the memory and the programming.
IMPORTANT:
The viscometer contains a default calibration element, the Factory Calibration,
which is installed during the manufacturing process. It is for this reason that it
is unnecessary to calibrate the equipment when using it for the first time.
Nevertheless, certain norms of quality recommend that the equipment be
recalibrated once a year. This is why it is offered the user the possibility of
realizing this calibration, the User Calibration, without needing to send the
viscometer back to the usual provider, or to Fungilab.
Fungilab cannot be held responsible for the measurements taken by an
independently recalibrated viscometer and it is essential to follow the
instructions given by Fungilab carefully when recalibrating.
Calibration Norms:
To execute a viscosity calibration it is necessary to have on hand at
least a little standard calibration oil and a thermo-statization system to
maintain the sample at a constant temperature. If you do not have this
equipment then you will not be able to guarantee good post-calibration
measurements. Fungilab provides upon request the standard oils
necessary for the calibration, as well as the accessories need to
thermostatize the oils.
There are two types of calibration:
oCalibration of reference spindle: These spindles are coaxial
spindles, with which the accessories APM or APM/B must be
used. By calibrating these spindles, you’re changing the
calibration of all of the viscometer’s spindles. Reference
spindles:
Model L TL5
Model R TR8
Model H TR8
oCalibration of the rest of the spindles: The calibration of any
spindle, which is different from the reference spindle, will only
modify the values of that individual spindle. The rest of the
equipment’s spindles will not be affected by this calibration. If
you want to calibrate more than one spindle and you don’t do it
with the reference spindle, the spindles will have to be
calibrated one by one. The oils used for each spindle will also
be different, so for calibration you should have standard silicon
oil for each spindle you’re calibrating.
Tables 5, 6 and 7 (page 67 and 68) specify the standard oils necessary
for each spindle.
This submenu is accessed through the main configuration menu, by choosing the Calibration menu
and pressing ‘ENTER’. Once at the submenu, the following screen will appear:

EVO EXPERT Manual 18/105
Using the ‘’ and ‘’ keys, you can select the different options of this submenu, highlighting each
option and pressing ‘ENTER’ for choosing it. Using the ‘◄’ key, you can return to the previous
screen and with the ‘MEM/CLEAR’ key you will return to the main menu. If you hit ‘ENTER’, you will
select the option indicated by the cursor.
8.2.4.1 Reset
This submenu contains the equipment’s RESET option.
After resetting, the equipment will recuperate the original viscosity calibration.
Upon entering this submenu, the following screen will appear:
If you want to continue with this process, hit ‘ENTER’ and you will be brought to the following
screen. Otherwise, hit the ‘MEM/CLEAR’ key, which will bring you back to the main menu. In this
submenu, the keys ‘’ and ‘’ have no function.
If you press ‘ENTER’ here, the factory-stage calibration will be restored (calibration, language), the
memory will be erased as well as the programming and you will return to the main configuration
screen. If you hit ‘MEM/Clear’, you will return to the main menu and by hitting ‘◄’, no configuration
will be restored and you will also return to the main configuration screen. If you press ‘ENTER’ with
the field ‘QUIT’ highlighted the system will return to the ‘CALIBRATION’ menu.

EVO EXPERT Manual 19/105
8.2.4.2 Viscosity Calibration
It will be described first the procedure to perform the Factory Calibration. Once the ‘FACTORY
CALIBRATION’ option is chosen you will be prompted for a password, as it is shown in the following
screen:
Once introduced the correct password the following screen will appear:
If you select the viscosity option (moving through the menu with the the ‘’ and ‘’ keys) and you
press ‘ENTER’ you will access to the following screens, depending on the model of your viscometer:
Model L
Models R and H

EVO EXPERT Manual 20/105
Upon entering this screen, the spindle field is highlighted in light blue background. Using the ‘’ and
‘’ keys you can change the Spindle.
The list of possible spindles to use depends on the model of your viscometer (L, R or H). Thus, in
tables 8 through 22 (page 65 and on) you can see the different spindles available for each model.
Note: It is recommended to use the following combinations of Spindle and standard
oil depending on the viscometer model:
Model L: TL5 Spindle (LCP adapter) and RT-50 (50 cP) standard
Model R: TR8 Spindle (LCP adapter) and RT-500 (500 cP) standard
Model H: TR8 Spindle (LCP adapter) and RT-500 (500 cP) standard
Once you’ve selected your spindle press ‘ENTER’ and the ‘VISCOSITY’ field will be highlighted. Press
‘ENTER’ again and the following screen will appear:
Use the numerical keyboard to introduce the value of the viscosity of the standard oil used for
calibration (the standard oils provided by Fungilab provide viscosity tables according to different
working temperatures). There is a field for entire numbers and other one for the decimal figures.
Once introduced the density value, press ‘ENTER’ with the ‘SAVE’ option highlighted to confirm the
modification. Next, the following screen will appear:
Remove the Spindle if it is connected to the viscometer and press ‘ENTER’. Then, the viscometer
will perform the Offset calibration, showing the following screen:
The screen shows the progression of this step of the calibration with a status bar. Once the Offset
calibration is completed, the following screen will be on:
