4.1 Instrument Controls
Figure 3: Instrument Descriptions
1. Power Switch. This switch controls the power
to the entire unit. When the power switch is in
the
ON position, the digital temperature
controller, the stirrer, and the optical sensors
power supply are powered on.
2. Lamp Switch. This switch controls turning
ON/OFF the lamp for illuminating the test
samples.
3. Temperature Controller. The temperature
controller regulates the bath temperature for
the test procedure. Refer to Section 4.3 for full
operational details.
4. Bath/ Bath Stirrer: The stirrer constantly
circulates bath medium to prevent
temperature gradients and ensures
temperature stability. When cleaning and/or
servicing, please be sure to disconnect unit
power to avoid possible injury.
5. Temperature Regulation: The heater coils
stabilize the bath temperature to desired
setting within ± 0.02°C. Running coolant
through the cooling coils allows bath to
maintain temperatures near or below ambient.
6. Viscometer Ports: The viscometer, once
engaged into the assembly, is placed into the
bath through the viscometer ports on top of
the instrument.
7. Thermometer/Thermocouple Port: This port
allows for independent temperature
measurement of the bath temperature with a
thermometer or a Pt-100 RTD probe for
precise temperature measurements and digital
temperature controller calibration. If the
controller needs to be calibrated, then please
contact
the Koehler technical service
department.
8. Optical Sensor Ports: The optical sensors
are connected to the instrument through these
ports numbered 1-5. Note that an outline of
the plug is provided to ensure that the plug is
inserted into the proper position.
9. Interface : Here the user can set operation
parameters and view results on the touch
screen digital display.
4.2 Accessories for Running Tests
Glass Capillary Viscometer Tubes for KV5000
Koehler offers a full selection of glass capillary
kinematic viscometers, which are ordered
separately from the KV5000 instrument, for
measuring kinematic viscosity of liquid products as
per ASTM D445 and related standard test
methods. All types of viscometers conform to
ASTM D445 and related methods for glass
capillary kinematic viscometers. All viscometers
with part numbers for the automatic test are listed
below. The constant for each individual viscometer
is written on the Certificate of Calibration, included
in the packaging.
IMPORTANT: It is recommended when using a
new viscometer for the first time to run a test with
suitable standard. Different locations may result in
a slightly different constant.
