II.3 SPEED SETTING
The is a single speed viscometer. It is supplied from the factory in two
configurations: standard and custom. The speed of rotation is shown in the lower
right corner of the display.
Standard
The Viscometer is supplied with two speeds: 750 RPM and 900 RPM.
All Viscometers are factory-set at 900 RPM. To change the setting, press
and hold the STOP key during the power up sequence. Choose “1=SPEED (RPM)”
from the special functions screen and select the required speed. This selection will
become the default speed.
Custom
The Viscometer is configured to operate at one speed as specified at the
time of order. This speed is indicated on the instrument serial tag.
To begin spindle rotation, press the
RUN key.
II.4 TEMPERATURE CONTROL SETTING
Press the TEMP key and the current temperature setting will blink. The default
temperature on start-up is 25.0°C on low temperature models and 50°C on high
temperature models.
The temperature ranges are:
Low temperature: 5°C (or 15°C below ambient, whichever is higher) to 75°C
High temperature: 50°C to 235°C
NOTE: The temperature can be set in increments of 0.1°C .
Use the number keys to type in the required set point.
Use the
ENTER key to accept the new set point.
NOTE: Thermal equilibrium of the sample and of the spindle must be considered
for best measurement results. Upon powering up the Viscometer or after
changing the temperature set point, allow sufficient time for the plate to
reach the desired temperature. It is recommended to have the spindle in
contact with the plate prior to introducing the sample material to ensure that
the spindle is also at the temperature of test. BYK-Gardner recommends
using the solvent trap at all times to enhance the temperature control of the
sample material. After inserting the sample material onto the plate, lower
the spindle and solvent trap and allow sufficient time for thermal equilibrium
prior to starting the test.
