Operation and Instruction Manual
KV5000-Manual
- 15-
NOTE: Do not attempt moving the bath
when filled with fluid medium. Drain all fluid before
moving or relocating the instrument. See section
7.2 of this document. Sudden starting and
stopping could result in hot bath fluid being
forcefully ejected from the bath. It could also result
in overbalancing and tipping over the instrument.
NOTE: Do not drain the bath until the fluid is at
ambient temperature.
Testing
Temperature
Recommended Fluid
15 - 50°C*
Distilled water will be suitable.
50 - 95°C Koehler supplies highly
refined white technical oil
(part # 355-001-001) that
contains an oxidation inhibitor
to limit clouding at higher
temperatures.
CAS# 8042-47-5
Minimum Flash Point: 120°C
(248°F)
Fire Point: 202°C (395°F)
95 - 150°C Koehler supplies a clear
silicone heat transfer fluid
(part # 355-001-002) with high
oxidation resistance and low
volatility. CAS # 63148-62-9.
Minimum Flash Point: 200°C
(392°F).
*For temperatures below 50°C, the KV5000 instrument
can only be used in Automatic Mode (See Section 5.5).
The low temperatures will cause condensation on the jar
surface compromising visibility of the viscometer tubes.
NOTE: Do not use bath fluids that will
decompose or volatilize producing flammable
vapors below the maximum instrument operating
tempe25°C.
NOTE: Coloration of the Mineral or Silicon Bath
Oil is an indication that the Medium must be
changed. See Draining instructions in section 7.3
of this document. When a decision is made to
discard this material, dispose of this material and
its container to a hazardous of special waste
collection point. Country, State, or local laws may
impose additional regulatory requirements
regarding disposal. Dispose in accordance to all
applicable regulations.
WARNING: Bath oils contaminated with
light ends can pose a flammability hazard.
5.2 Power
Turn on the main power switch to the unit.
WARNING: Do NOT turn the power on
unless the bath is filled with the proper medium;
otherwise, damage may occur to the unit and the
warranty would be void.
5.3 Engage the Viscometer in Optical
Sensor Assembly
NOTE : Before engaging the viscometer, make
sure the optical sensors do not extend beyond the
inner wall of the clamp. They should be flush with
the clamp wall. Refer to Figure 5, showing both
correct and incorrect orientation of sensors.
Figure 5 Optical Sensors in the Clamp
To insert the glass viscometer tube into the optical
sensor assembly, orient the tube such that the
timing marks on the viscometer tube will line up
with the optical sensor devices. Place the base of
the tube into the optical sensor assembly first as
shown in Figure 6.
