NOTICE
The following precautions should be observed to avoid possible exposure to excessive microwave energy if using
the SMART 6 Moisture/Solids Analyzer:
• Do not tamper with the safety interlocks. The SMART 6 is equipped with three safety interlocks which prevent the
instrument from producing microwave power if the cover is open.
• Do not place any object between the SMART 6 cavity and the cover, or allow soil or cleaner residue to accumulate
on sealing surfaces.
• Do not operate the instrument if it is damaged. It is particularly important that the instrument cover close properly
and that there is no damage to the cover (bent), hinges and latch (broken or loosened), or sealing surfaces of the
SMART 6.
• The instrument should only be adjusted or repaired by qualified service personnel.
The following precautions should be observed to avoid instrument-induced electromagnetic interference:
• The possibility of instrument-induced electromagnetic interference (EMI) is minimal if the precautions outlined
above are followed.
• The ORACLE should not be placed close to any electrical device susceptible to EMI. It is suggested that the user
post a sign warning pacemaker wearers that a device utilizing microwave and magnetic fields is in operation.
• If the SMART 6 is suspected of inducing EMI, please contact the CEM Service Department to perform a Microwave
Leakage Test.
This instrument utilizes high voltages and microwave radiation.
• Instrument service and repair should be performed only by those trained in repair and maintenance of high
voltage and microwave power systems.
• If the ORACLE or SMART 6 are used in a manner not specified by CEM Corporation, protections provided by the
systems may be impaired.
Warnings, cautions, and notes are included throughout this manual and should be read thoroughly and strictly
followed.
WARNING: A warning is inserted for essential information used to emphasize dangerous or hazardous conditions to
the operation, cleaning, and maintenance of the instrument which may result in personal injury.
CAUTION: A caution is inserted for essential information used to emphasize procedures which, if not strictly
followed, may result in damage or destruction of the instrument or improper instrument operation.
NOTE: A note is inserted for emphasis of procedures or conditions which may otherwise be misinterpreted or
overlooked and to clarify possible confusing situations.

Introduction
The ORACLE Universal Fat Analyzer offered by CEM utilizes proprietary nuclear magnetic resonance (NMR) signal
gathering to accurately measure the fat content of any product without the need for method development. The
ORACLE is the first rapid, non-destructive technology able to provide a primary fat analysis, as opposed to the
secondary analysis techniques employed by other rapid technologies (i.e. NIR, FT-IR, FT-NIR, and traditional TD-
NMR). Using the ORACLE, a sample is dried to remove any free moisture that may cause interference, then
conditioned to an optimal temperature using a stand-alone heater block or the internal QuikPrepTM heater. The
NMR then sends a pulse of radio-frequency energy through the sample, causing any hydrogen protons specific to fat
molecules to generate a response signal. This signal is recorded and calculated to represent the percent of total fat
in the sample, typically taking less than 45 seconds for the entire process.
The ORACLE consists of an NMR magnet to perform the fat analysis, an electronics box (listed as processor box) for
controlling and storing system settings and data, and may also include a SMART 6 Moisture/Solids Analyzer for rapid
moisture analysis and sample drying prior to testing in the magnet. The ORACLE utilizes a glass-capacitance
touchscreen for intuitive testing and data maintenance, and employs the use of internal diagnostics to ensure full
system functionality.
ORACLE is the first rapid fat analysis system that requires no method/channel development and directly analyzes
fat/oil in food samples. The system is rapid (45 second analysis), requires no solvents or chemists, and prevents
operator to operator error and is not prone to potential issues encountered during wet reference chemistry. Since
ORACLE is a direct technique and measures the entire sample, there are no costly method recalibrations or method
development required. Once installed, the ORACLE is ready to accurately and repeatably measure fat/oil in any
unknown food sample.
Despite the word “nuclear” in the name, NMR does not use or generate radiation. The word “nuclear” in NMR refers
to the instrument’s ability to analyze the nuclei of the sample.

Safety Overview
To the best of our knowledge, the information contained herein is accurate. However, CEM cannot accept liability of
any kind for the accuracy or completeness of the information contained in this manual. The final determination of
the suitability and proper use of the instrument described herein, the accuracy of the information and data obtained
from such use, and whether such use infringes any patents or the legal safeguards of others are the sole
responsibility of the user.
WARNING
To avoid degradation of the ORACLE magnet performance, or operator injury, do not place
ferromagnetic items (e.g. mechanical tools) near the magnet. Magnets can attract ferrous objects,
turning them into projectiles and causing injury.
To prevent injury from high voltages, do not remove instrument covers or components unless you are
trained in the repair of high voltage instruments. All components of this instrument utilize high
voltages. Instrument service and repair should be performed only by those highly trained in repair and
maintenance of high voltage and microwave power systems.
Samples that can be considered flammable, corrosive, poisonous, or explosive must be discussed with
the Process Applications group at CEM Corporation prior to analysis in the ORACLE. Failure to obtain
approval from CEM Corporation can create a dangerous testing environment and will void any
warranty.
When using the SMART 6, analyzing solvents or products containing harmful volatiles requires the
connection of an exhaust hose to the exhaust assembly located on the rear of the instrument. The
exhaust hose must lead to an approved fume containment or ventilation system.
Proper handling of dangerous materials must be followed based on the SDS (Safety Data Sheets) of the
material to ensure a safe testing environment.
Certain pace makers and other magnetically sensitive prosthetic devices may be affected by magnetic
fields used in the ORACLE. It is recommended that users with these prosthetics do not approach the
ORACLE within 11 in (0.3m).
The ORACLE is susceptible to electromagnetic interference, and should not be placed close to any
electrical device that emits EMI. If there are any uncertainties to the level of EMI being emitted by a
nearby instrument, please contact CEM about the options available for ensuring an optimal testing
location.

System Installation
Unpack System Note
Retain all packing materials.
1. Following the instructions below, carefully remove the instrument and place it on a vibration-free workbench
or laboratory table in a location that:
a. provides a draft free, dust free, dry environment. The temperature of the room must be between 50 °F
and 85 °F (10 °C - 29 °C). Temperature should not vary more than 5 °F (2.5 °C) per day. Relative
humidity range should be 0-85%. Take special care to avoid areas positioned directly
underneath or in line with an air conditioner or similar source of air drafts.
b. is free from vibration of large equipment and/or excessive walk-through traffic.
c. is capable of supporting the combined weight of the ORACLE magnet (120 lbs/55 kg) and, if
applicable, the ORACLE processor (37 lbs/17 kg) and SMART 6 (55 lbs/25 kg).
d. does not have a steel (iron) top. Materials such as wood, plastic, aluminum, or non-magnetic
stainless steel are suitable surfaces. Ensure that no steel bar, supporting the work surface, runs
directly beneath the magnet. Any cabinets directly beneath the magnet should be cleared of
metallic materials (though the cabinets themselves can be metallic).
