1Generalities
Before any use, read carefully the technical manual in order to ensure the good installation of
the unit.
1.1 Navigation
: Press on this key enables to return to the previous level.
: Press on this key enables to return to the “Bargraphs” view (see § 2.1).
1.2 Diagnosis
When an anomaly is detected by the processor, the symbol appears on the main “Bar-
graphs” view.
Press F6 and the details about the anomaly appear.
Type of anomaly:
-Out of range: Viscosity.
We consider that the sensor is out of range when viscosity exceeds 110 % of full scale range.
-Out of range: Offset.
An offset setting is needed. It means that Vbrut needs to be shift to the reference 9000mV.
It is necessary to respect the method of Offset setting described on § 5.1 “Set the Offset”.
-Out of range: Compensation table.
The referenced temperature, that can be set on “Compensated viscosity” view (see § 2.2) or
the instantaneous temperature is out of the table.
-Alarms.
Message that appears at the reach of the low or high threshold for viscosity, temperature or
density.
-Rupture.
Message that appears when there is a rupture (viscosity, temperature or density) generally re-
lated to a connexion problem.
1.3 Security codes
4 security codes, CODE 0 to CODE 3, are defined.
Refer to:
-Technical manual : §7 –Specific notes and manufacturing parameters
-User manual : §6.4 –Modify security codes

4.5.2 Relays status
It makes it possible to visualize the status of the relays allocated to viscosity, compensated vis-
cosity, temperature and density alarms.
Relays are NO type.
Under normal functioning, the coils of the relay are under tension and the contact is closed.
In anomaly, the coils are not under tension and the contact is opened: measurements out of set
point, processor power supply is turn off…
The setting of High and Low thresholds is made starting from the block “Settings”.
4.5.3 Raw data
This view is intended for SOFRASER after sales service.
In the case of a special calibration, this window can change and display more parameters (2 pages).

5Block “Settings”
5.1 Set the offset
Air is used as reference fluid in order to adjust the raw signals during the installation.
The offset adjustment must be done:
At each new installation of the sensor on the process
At each observation of the signal drift in the air (§ 4.5.3).
Each time the information is indicated on the “Diagnosis” view.
The stages to follow to proceed to the offset adjustment are describes below:
Step 1
Enter in the “Settings” block
Step 2
Enter the security CODE 2 and choose the function “Offset”.
Step 3
Clean the sensor rod and make sure that it is clean and dry.
Step 4
Make sure that the process is empty so that the sensor is vibrating in the air during the
adjustment, i.e. that the rod is not immersed.
Step 5
Install the sensor using the fastening screws.
Step 6
Adjust the assembly offset in the air to fix Vbrut to the reference of 9000 mV by pressing
on the F3 key “Shift”.
Step 7
Press on OK to take into account the offset adjustment.
Step 8
Confirmation of the adjustment validity :
The offset adjustment is successful :
Press on
The offset adjustment has failed :
Start again : press on OK
Ignore : press on ESC
Consequences of a failed offset adjustment:
Viscosity is calculated starting from the amplitude corrected with offset.
So, if the offset is not adjusted correctly, the viscosity value will be false.
5.2 Set the alarms
It makes it possible to set LOW and HIGH thresholds and hysteresis of viscosity, compensated
viscosity, temperature and density alarms.
Pressing OK does the navigation from one threshold to another.
The modification of a value is done using the keyboard. Pressing on OK will immediately take
the value modified into consideration and will make it possible to skip to the following threshold.

User Manual 9601
Ref.: 237/5 13
Low threshold of temperature alarm
Hysteresis of low threshold
Example:
Alarm 1 = alarm corresponding to the viscosity LOW threshold
Alarm 2 = alarm corresponding to the viscosity HIGH threshold
Viscosity unit = cP
LOW threshold = 15
Hysteresis = 5
Alarm 1 is activated when the viscosity reaches 10 cP. It stays active as
long as viscosity does not reach the set point 15 cP.
The relay associated is opened as long as Alarm 1 is activated.
HIGH threshold = 100
Hysteresis = 10
Alarm 2 is activated when the viscosity reaches 110 cP. It stays active as
long as viscosity does not reach the set point 100 cP.
The relay associated is opened as long as Alarm 2 is activated.

5.3 Set and test the current outputs
5.3.1 Set the current outputs
It makes it possible to set viscosity, compensated viscosity, temperature and density current
outputs.

User Manual 9601
Ref.: 237/5 14
Minimal physical viscosity value: 0.0 cP
Value of the current output for the minimal physical value: 4mA
Maximum physical viscosity value: 1000.0 cP
Value of the current output for the maximum physical value: 20mA
Burn: Value of the current output in the event of rupture of the measurement signal.
Pressing on OK does the navigation from one value to another.
The modification of a value is done using the keyboard. Pressing on OK key will immediately
take the value modified into consideration and will make it possible to skip to the following thresh-
old.
5.3.2 Test the current outputs
Code 1 is needed to access this testing function.
This function permits to SOFRASER after-sales service to test current outputs by generating a
current.
To test an output :
For the output you want to test, define a current on this view:
Measure the signal on the appropriate connector on the back module of the equipment. The
measured signal should be equal to the defined testing current.
You have to stay on the view “current generator” to proceed to the test.
COM + AOUT 0: viscosity current output
COM + AOUT 1: temperature current output
COM + AOUT 2: compensated viscosity current output
COM + AOUT 3: density current output

User Manual 9601
Ref.: 237/5 15
5.4 Choose the method of kinematic viscosity calculation
It is possible to calculate the kinematic viscosity in 2 ways:
Starting from the density measured by a densimeter (in option):
When the 9601 processor is delivered with a densimeter, the density input configu-
ration (4/20 mA) is the following one:
4 mA →0,4 g/cc
20 mA → 2 g/cc
By considering that the density is constant.
The choice of the calculation method is done by selecting it with the arrows.
Caution: if the user chooses to work with kinematic viscosity values, the viscosity unit (§ 4.2)
must be “ cSt “ in order to activate the conversion.
5.5 Set the bargraphs
Bargraphs are displayed on the main view, which is accessible by pressing on .
The bargraphs scales require to be modified during a change of viscosity or temperature unit in
order to remain in coherence with the range of the physical units.
Only high thresholds of bargraphs can be modified.
The modification of a value is done using the keyboard. Pressing on OK key will immediately
take the value modified into consideration and will make it possible to skip to the following thresh-
old.
5.6 Set the graph scales
It makes it possible, for the user, to set the working range to visualize on the acquisition graph:
minimum and maximum of the scales and acquisition frequency.
Scale minimum
Always equal to 0
Acquisition frequency
Minimum : 1s
Maximum : 120s
Number of points
120 points
By default:
Scale maximum: equal to the maximum of viscosity and temperature range.
Acquisition period: 30s.
The scales must be verified and adjusted following:
Modification of the viscosity unit (§ 4.1)
Modification of the temperature unit (§ 4.2)

User Manual 9601
Ref.: 237/5 16
Example:
Acquisition time:
A point will be recorded and traced every sec-
onds. The graph will represents 2 minutes of
acquisition.
5.7 Activate the Pt100
With Pt100: makes it possible to activate all displays and functions related to
the temperature.
Without Pt100: when the temperature measurement is not available or when
the user prefers to work without temperature indication.
It will cancel all displays (bargraphs, graphs, instantaneous measurements) and will block the
access to all the functions related to the temperature (temperature unit, temperature and viscosity
compensated alarms, temperature and viscosity compensated current outputs, compensation ta-
ble…)
5.8 Define the filter
This function permits to activate and define parameters of the viscosity filter.
Two parameters need to be defined by the user :
Samples number: number of values that are used to calculate the averaged viscosity.
Four possibilities are proposed (4, 8, 12 or 16 values) and the user can deactivate the
filter by choosing “no filter”.
Sampling period : this period corresponds to the new viscosity value acquisition period.
At each period, a new value enters in the table and the oldest is getting out. The filtered viscosi-
ty is updated.
Four periods are proposed (50, 100, 200, 400 ms) and the user can define an other period from
50 ms to 36000 ms.

User Manual 9601
Ref.: 237/5 17
The first filtered viscosity value is calculated (samples number * sampling period) after the
starting of the sensor.
For example:
Samples number = 12 –Sampling period = 100ms
