press the Start button on the Control
Panel. The viscometer status, which as a default
displays
OFF, will change to RUN and the
integrated timer will begin.
When the sample passes the second indication
line, press the Stop button . The time will
stop, the status will display DONE , and a
viscosity value will automatically be displayed at
the bottom of the Test Data area (Figure 3, point
4).
Pressing and holding the Stop button for
2 seconds or more will reset the time and
viscosity values and OFF will display as the
status.
When using a viscometer with two (2) constants,
two (2) time values are used to calculate
viscosity. This means that when running a
viscosity test using a two constant viscometer
the Stop button must be pressed twice.
When the sample passes the first indicator line
the
Time 1 will stop and Time 2 will begin. The
status will change from RUN to RUN 2 .
Once the sample passes the second indicator
line on the viscometer tube, press the Stop
button a second time and the TIME 2 will
stop. The status will change from RUN 2 to
DONE and the viscosity value will automatically
be calculated and displayed.
6 Safety Features
The Koehler KV4000 Kinematic Viscosity
System is equipped with several safety and
protection features, which are described in the
following sections.
WARNING: The bath is NOT Explosion
Proof.
6.1 Over-Temperature Protection
The Koehler KV4000 Kinematic Viscosity
System is equipped with Over-temperature
Protection (OTP) circuitry, which prevents the
unit
from exceeding unsafe operating
temperatures. If the unit cannot maintain the set
point temperature and begins to decline, the
OTP circuitry may have been activated. Please
follow these steps.
1. Turn off the unit power switch and
disconnect the line cord.
2. Determine the source of the problem and
correct the situation.
3. Restart the unit. Monitor the operations to
ensure that the unit is operating properly. If
you are still experiencing trouble, please
contact
Koehler technical service for
assistance.
6.2 Over-Power Protection
The Koehler KV4000 Kinematic Viscosity
System is equipped with Over-power Protection
circuitry, which prevents the unit from unsafe
electrical conditions. If power to the unit is lost,
then turn off the main power and turn it back on
again. The main power switch also functions as
a circuit breaker.
7 Troubleshooting
WARNING: Troubleshooting procedures
involve working with high voltages and/or
temperatures which may result in personal injury
or death, and should only be performed by
trained personnel. Please do not hesitate to
contact Koehler for assistance.
