Staff Update<br />
Mal & Evie just getting ready to start a game in the<br />
office - it starts with a gentle torment and then<br />
fires up to tumbling and chasing<br />
At last there has been some well needed rain in<br />
Bacchus Marsh, not enough to do more than just<br />
wet the ground, but every drop counts.<br />
With the colder weather now approaching, both<br />
Mal & Evie spend more time in the office keeping<br />
warm.<br />
A game of chase in the office is often on the cards<br />
– it certainly breaks the routine of the day for<br />
them, and also for all of us. When the game is<br />
over, they are happy to lie back and catch up on a<br />
bit of shut eye. It doesn’t seem to matter to them<br />
where they lay down, they are happy for us to walk<br />
around them or over them – once they are settled<br />
they are down for the count – happy to rest and<br />
recuperate.<br />

Service Department Update<br />
all industries<br />
Recently, our service engineer<br />
Richard Donaldson has been<br />
travelled around Australia<br />
conducting installations<br />
and calibrations on a variety<br />
of the HAAKE Viscometers<br />
and Rheometers.<br />
Additionally, there were installations during this<br />
period for Optical Control Systems products.<br />
During an eight week period he has carried out<br />
calibrations on the HAAKE Viscotester VT550,<br />
HAAKE RheoStress, HAAKE RheoStress 600,<br />
HAAKE RheoStress 100 and HAAKE RotoVisco<br />
RV1. A total of 28 viscometers and rheometers<br />
have now been calibrated across, Queensland,<br />
Victoria, South Australia, Western Australia and<br />
New South Wales. His frequent flyer miles by now<br />
will be adding up to a sizable amount and well<br />
deserved.<br />
Just to ensure that he was kept fully occupied, he<br />
has also been involved in the installation of three<br />
HAAKE PolyLab's –one in Victoria and two in<br />
Queensland, and one PRISM EuroLab 16 mm twin<br />
screw extruder in Victoria.<br />
But the installations didn’t stop with the<br />
rheological instruments; there were also a<br />
number of Optical Control Systems (OCS) units<br />
installed during this same eight week period both<br />
into Victoria into separate companies. The<br />
systems installed were the OCS Surface<br />
Inspection system for the laboratory - FSA100,<br />
and the modular surface inspection system for<br />
in use in production - FSP600.<br />
Calibration overview<br />
The ability of a measurement device to accurately<br />
measure a physical quantity changes with a<br />
number of factors. Time in service, temperature,<br />
humidity, environmental exposure, and abuse can<br />
all affect your measurement accuracy of your<br />
instrument.<br />
Calibration quantifies this change in measurement<br />
accuracy and, when required, adjusts the device's<br />
measurement capability to decrease error.<br />
Whether your calibration needs are driven by<br />
ISO-9000 requirements, by company mandates, or<br />
by Good Laboratory Practice, <strong>Rheology</strong> <strong>Solutions</strong><br />
Pty Ltd can tailor our service to suit your needs.<br />
Why Re-Calibrate?<br />
The accuracy of the electronic components used<br />
in all instruments drifts over time. The effects of<br />
time in service as well as environmental conditions<br />
add to this drift. As time progresses, changes in<br />
component values cause greater uncertainty in<br />
your measurements. At some point in time, the<br />
drift causes the instrument's uncertainty to<br />
become undefined, meaning the manufacturer can<br />
no longer predict the uncertainty and guarantee<br />
measurement results. To resolve this issue<br />
instruments must be calibrated at regular intervals<br />
as defined by the manufacturer.<br />
Richard Donaldson, Service Engineer<br />
Calibration is the comparison of an instrument's<br />
performance to a standard of known accuracy.<br />
The result of a calibration may be documentation<br />
showing the deviation of a measurement from the<br />
known standard or it may also include adjusting<br />
the instrument's measurement capability to<br />
improve measurement accuracy.<br />
The goal of calibration is to quantify and improve<br />
the measurement accuracy of your instrument.<br />
The benefits of maintaining properly calibrated<br />
equipment include:<br />
• Reduced measurement errors<br />
• Consistency between measurements<br />
• Increases in production yields<br />
• Assurance you are making accurate<br />
measurements<br />
We recommend that you periodically calibrate your<br />
hardware to ensure measurement accuracy and to<br />
keep your devices operating in peak precision.<br />
If you have any queries regarding the timing<br />
or arranging for your HAAKE viscometer or<br />
rheometer to be calibrated, contact Jackie by<br />
