INTRODUCTION
Purpose of the manual This manual has been written to provide the information necessary for
proper installation, operation, and maintenance of the
CANNON ® Mini-
Rotary Viscometer (CMRV-4500).
Instrument utility The CANNON ® Mini-Rotary Viscometer is used to measure the apparent
viscosity and yield stress of engine oils and drive line lubricants within
the temperature range of -10
° C to -40 ° C using ASTM test methods D
4684, D 3829, D6821 and D 6896. ASTM test method D 4684 is required
by the Society of Automotive Engineers (SAE) Engine Oil Viscosity
Classification SAE J300.
NOTE The CMRV-4500 capabilities have been tailored to the requirements of
the current ASTM methods cited above. For this reason, the instrument
may not be suitable for some general-purpose viscometry applications.
Consult with CANNON
® Customer Service before testing with materials
and/or methodology at significant variance with ASTM D 4684, ASTM D
3829 or ASTM D 6821.
Improvements The CMRV-4500 is a state-of-the-art system offering many superior
features including:
New Method compatibility
The CMRV-4500 is fully compatible with ASTM D 6821,
the new Drive Line Lubricants test method. The CMRV-4500
is fully compatible with ASTM D 6896, a new method for
testing used diesel oils.
Improved insulation for temperature control
The CMRV-4500 instrument features a redesigned housing
and accessory rotor caps to enhance insulating characteristics
and precision.
Software library of temperature profiles
(cooling profiles)
Predefined cooling profiles that comply with methods ASTM
D 3829, ASTM D 4684, ASTM D 6821 and ASTM D 6896
are supplied with the CMRV software. The user may also
create custom cooling profiles with the Profile Designer.
