value can be found on the calibration
certificate provided with the viscometer.
5. Constant #2. Press the Constant #2 button to
input a second viscometer tube constant value
using the pop up numerical keypad. A second
constant value can be found on the calibration
certificate provided with viscometers that
utilize two constants. E.g. Cannon-Fenske
Opaque Type.
6. Save to Preset. After inputting the viscometer
parameters: Serial #, Type, Size, Constant,
pressing the Save to Preset button
will save the input parameters to one of the 20
available memory programs. The user can
then easily access the information of a specific
viscometer by scrolling the memory presets
using the up and down arrows.
7. Up Arrow. Press the up arrow to scroll
through the 20 available viscometer preset
programs.
8. Down Arrow. Press the down arrow to
scroll through the 20 available viscometer
preset programs.
9. Enter. Once you have input the viscometer
parameters, saved to a selected preset and
chosen that particular preset, press the enter
button to export the viscometer
parameter data to the main menu screen. The
viscometer data entered / chosen will
automatically be uploaded to the main menu
and will be displayed in the Viscometer Data
box.
5.6 Test Procedure
A quick guide for operating the KV5000 Low
Temperature Kinematic Viscosity System is given
below. Use this guide along with an applicable
standardized test procedure listed in section 1.2 of
this
document when performing Kinematic
viscosity testing.
After the main power switch to the instrument is
turned on, the control panel will illuminate and
display the Koehler Instrument Splash Screen.
After a few seconds the main screen will display
on the control panel. See Figure 3 in section 5.3
and Figure 5 below for an additional illustration of
the main screen.

NOTE: Detailed descriptions for the functionality of
each button are described in section 5.3 of this
document.
Verify that the bath medium had come to
equilibrium at the required test temperature as per
section 5.2 of this document.
Fill viscometer tube with test sample using a
laboratory funnel or other filling device.
Pull the sample through the viscometer tube using
a withdrawal bulb or vacuum system to the initial
testing position above the first line. This is also
called charging the viscometer.
Place stopper in the top of the viscometer tube
and remove the withdrawal bulb.
NOTE: The procedure for charging a specific
viscometer will vary depending on the viscometer
used. Please refer to ASTM D446 or related
international specification for a detailed charging
procedure specific to the viscometer tube being
used.
Engage
the charged viscometer into an
appropriate viscometer holder and place into one
of the seven available ports through the top of the
viscosity bath.
The sample temperature must come to equilibrium
with the bath temperature prior to testing.
Depending on the sample type, this process could
take 30-45 minutes. Use this time to input the
required viscometer data into the control panel.
