1. Tra smitter pri ciple
T e measuring c ain is composed of t ree inseparable elements: t e sensor, its cable and t e 9100
transducer t at controls it. T e sensor cannot be used wit anot er transducer or anot er
cable type or lengt because t ey are all a part of t e resonant loop so t ey are matc ed
toget er as one vibrating system.
T e active part of t e sensor is composed of a vibrating rod eld in oscillation at resonance frequency
by driving magnets. W en t e rod is immersed into a viscous material, t e amplitude of t e
vibration is dampened. T e vibration amplitude varies according to t e product viscosity
w ere t e rod is immersed.
T e sensor receiving coil detects t e response and t e signal is converted to a viscosity value
t roug t e electronic device. T e factory calibration is performed wit standard oils.
T e transducer acquires t e coils’ amplitudes and frequency and generates various signals. T ese
signals represent t e properties being measured. It is also in c arge of powering t e w ole
system. It gives viscosity and temperature information t roug t e serial communication and
displays it. T e transmitter also allows simple settings as t e very important “zero in t e air”
procedure.

and ot er information specific of t e unit.
Mainly, t ese data are used to diagnose w en somet ing wrong appens wit t e sensor.
Passing from one screen to t e next is done t anks to OK button and t e order is as follow:
AMP: T e amplitude value, image of t e amplitude of t e oscillating rod wit no correction
and no calculation.
FRQ: T e frequency of t e vibration.
C: T e coil value, image of t e inner temperature.
TC: T e inner temperature.
PROG: T e program version is displayed for after-sale purposes.
T e serial number of t e sensor (4 digits) and t e electronics (3 letters).
D: T e date of manufacturing.
FSR: T e viscosity range of t e sensor.
Exit t is menu by pressing Home.
3.3 Offset
In t is menu, we set t e zero in t e air. T is is a very important step in t e installation procedure of
t e equipment and it must be done eac time t e sensor is installed again after being
removed for cleaning, calibration or maintenance.
Before proceeding to t e zero setting, t e rod must be clean and dry. Be sure t e process is empty
and t at t e rod is vibrating in t e air at a stabilized temperature. T e sensor must be fixed on
its final position and will ave to remain so. If not, t e offset calibration will ave to be done
again.
Press OK to enter t e Offset menu. Two warning messages will appear w en pressing OK
confirming t at t e rod must be clean and dry. If OK is pressed, t e transmitter calculates and
t en displays after a couple of seconds t e new adjusted value ( ere -26). T e user can validate
t e new offset pressing OK or e can get out of t e menu by pressing Home.

T e viscosity signal delivered to t e outputs of t e electronic device is calculated by using t e
adjusted amplitude of t e rod. If t e offset is done in a wrong way or as been forgotten, t e
viscosity value will be wrong.
It is THE essential setting during installation and as to be performed wit t e most extended
attention in order to set t e MIVI in its best conditions for optimal measurements.
Note: T e user s ould wait at least one minute between two zero adjustments, in order to get
accurate signals and calculations.
If t e offset is not done correctly, a warning message will appear:
T is message appears automatically w en t e offset value is too ig (or too low in t e negative). If
so, c eck t at t e sensor is correctly installed on t e process, wit t e vibrating rod clean and
dry and let t e unit stabilize. T en redo t e zero in t e air procedure.
If t is message remains even after carrying all t e precaution recommended by Sofraser, t e end-
user can anyway validate t e Offset value by pressing OK and t en OK again after a last
validation screen.
3.4 Viscosity and temperature units
It is possible to select t e viscosity and t e temperature units for t e main display on t e LCD screen.
Press OK to enter t e menu, c oose between t e different units by pressing OK and validate t e
c oice wit Home.
T e c oices are mPa.s and Pa.s for t e viscosity and degree Celsius (°C) or degree Fa ren eit (°F) for

Do not use an active tester (write mode), only use a passive tester like an ammeter (read mode).
By pressing OK, it sends t e first current value (04 mA). T en by browsing wit OK, it goes to t e
next two values (12 mA and 20 mA).
Exit t e menu by pressing Home.

5. Sofraser I terface Software
T e Sofraser Interface Software (SIS) as been designed for working wit t e 9100 transmitter. It
allows t e communication between t e electronic board of t e 9100 and a computer in order
to make some data logging or to set some parameters.
T is software as been designed to work on Windows XP, Windows Vista, Windows 7 and Windows
10 systems. T e communication is establis ed t roug t e RS485 port, MODBUS (code RTU)
protocol.
T is is optional and is not included in standard wit 9100 device.
5.1 T e main features
T e main features of t e SIS are as following:
display and refres t e dynamic values from t e sensor: viscosity, temperature (w en t ere
is a Pt100 probe), amplitude, coil and frequency signals
make t e zero adjustment in t e air
data log of t e dynamic values in an Excel file
adjust some correlations for t e viscosity
5.2 T e user-friendly interface
W en connecting t e 9100 to a computer, c oose t e COM port on w ic is connected t e
viscometer. T en click on t e double arrow button; t e SIS will automatically detect t e board,
display t e serial number of t e device and open a new window. T e user is ready to start
working wit t e equipment.
Eac equipment is protected wit a registration. At first use, you will ave to activate t e software
by entering t e registration key given by Sofraser (go to menu “File\Add Sensor” or “F6”). From
t en on, t e SIS installed on t is computer will always be able to communicate wit t e 9100.
Different levels of security ave been set up in t e SIS, so t at different users can ave different
possibilities on t e equipment t roug menu “Options\Connect As” or “F9”.
