Instrument Safety Notices
MAINTENANCE INSTRUCTIONS WITHIN THIS MANUAL ARE FOR USE BY QUALIFIED SERVICE PERSONNEL
Disconnect all temperature probes and turn the unit off before removing the battery cover.
Never connect thermocoup le leads to any s ource where mo re than 4 2 Vol ts (peak) could e xist
between the lead and ground. If it is necessary to make measurements of an object at elevated
electrical potential, the user is responsible for obtaining and properly using a probe that provides
adequate insulation between the surface with elevated potential and the thermocouple wiring.
Always disconnect probe leads before opening the battery door or the instrument housing.
Internal circuits can present a shock hazard if leads are connected to a source of elevated potential.
Do not use this instrument if the housing, probe wiring, probe, or probe handle are damaged
or distorted. Housings and wire insulation are part of the personnel protection system, and if damaged
Never use or store this product with batteries installed, or change batteries, in an
environment where explosive or flammable vapors or dust suspensions may exist.
Do not attempt to recharge alkaline batteries.
Do not put batteries into bags designed to protect parts from electrostatic discharge (ESD).
These bags are specially designed with metal shielding which can short circuit a battery.
Do not expose batteries to extreme heat or fire. Observe all regional laws and regulations when
disposing batteries.

RISK OF INSTRUMENT DAMAGE
care to avoid static discharge when handling the instrument or connected probes.
BURN HAZARD
Do not touch a temperature probe sheath that has been exposed to toxic substances or
extremely high or low temperatures.
Do not attempt to measure temperatures beyond the range of the temperature probe. Probe
Do not use when AC or DC voltages in excess of 1V exist between thermocouple channels (on
instruments with more than one channel). Excessive voltage could result in an incorrect reading, or
in more extreme cases, a blown fuse that will result in incorrect readings and need for repair.
Only replace batteries with size AA (IEC LR6, ANSI 15). Observe proper polarity when installing
batteries. Do not mix old and new batteries.
Do not apply voltages across thermocouple leads in excess of normal thermocouple voltage for
the se lected range. Excessive input voltage could result in blown fuse, component damage, or fire.
Application of excessive voltage is not covered by the warranty.
Avoid making sharp bends in probe or sensor lead wires. Bending lead wires at sharp angles can
damage the wire and cause probe failure.
When using both thermometer inputs and a voltage differential exists between the two
measurement points, at least one probe should be electrically insulated. If not, a ground-loop
current can flow through the thermocouple leads causing measurement error or instrument damage.
Static discharge through a connected temperature probe may cause instrument damage. Use
RISK OF INCORRECT READING
CAUTION

Preparation for Use
Always turn the instrument off and disconnect any input connections before replacing
instrument.
Remove the batteries when storing the instrument for an extended period of time or
to the instrument.
Unpacking and Inspection
Each instrument is electrically and mechanically inspected before shi pment. Upon receiving
your new OMEGA Data Thermometer, unpack all items from t he shipping containe r and
check for any obvious damage that ma y have occu rred during transi t. U se the ori gi nal
packing materials if reshipment is necessary.
If any dents, broken, or loose parts are seen, do not use the equipment. Notify OMEGA
immediately.
Check that all items are present. If any items are mis sing , notify OMEGA immediately.
The following items are included with every new instrument:
• One (1) Data Thermometer;
• One (1) Quick Start Guide;
• Statement of Traceability;
• Three (3) AA, 1.5 V batteries;
• One (1) Tilt Stand/Magnet/Hanger; and
• HH911T-070 Type K Wire Probe (quantity One (1) for HH931T, Two (2) for HH932T).
• Optional accessories (if purchased).

Making Your First Temperature Measurement
OMEGA’s 900 Series Data Thermometers are desig ned for easy operation, while still
providing a feature-ri ch experience via the intuitive user interface.
To get started maki ng temperature measureme nts right away, follo w th e se steps:
1. Perform Section 2.5, Ba ttery Insta ll ati on and Repla cem ent;
2. Connect a compatible temperature probe to the Channel 1 and/or Channel 2 inp ut
connector located at the to p of th e i nstr umen t;
To ensure best measurement accuracy, allow several minutes for the
thermocouple probe and connector to thermally stabilize af ter
connection to the instrument.
3. The instrument will immediately display a temperature measurement for the
connected channels. However, to ensure valid and best accuracy measurements,
continue to Step 4 below;
4. Set the desired measurement parameters as follows:

Press to hold the current reading and/or statistics result, and to pause statistics
accumulation. HOLD is displayed at the top-left of the LCD display. New measurements a re

Trend Indicators
Trend indicators provide a visual representati on of the m easu reme nt’ s sta bil ity, and

Battery Indicator
Battery depletion or battery replacement will reset all measurement p a ram ete rs to

Measurement Data Collection Overview
The data collectio n features of the OMEGA Data Thermometers accurately record an d st ore
accurate time stamped measurements at t he t ouch of a button. Saved data can be reviewed
on the device, or upl oaded to the OMEGA Data Cloud via the OMEGA Thermometer Link
mobile app.
Measurement data is collected automatically at user-programmed inter v al s, o r manually as
desired by the user. All saved meas uremen ts can be viewed directly on the instrument,
monitored in real -time with the mobile app, or reviewed, analyzed, and download e d f rom
the OMEGA Data Cloud.
Each saved measurement incl u des a time and date stamp b ase d on the date and time
programmed into the i n s t rum e n t. Through the mobile app and OMEGA Data Cloud, data
collection session s c an be associated with user-customizable locations to establish an
auditable record for a gi v en ass e t, p rod uct, batch, bin, etc.
Measurement Data Collection Configurations
Data collection can be accomplished using three dis ti n ct configurations to provide the most
flexibility and adaptability based on equipment availability and internet or cellular access.
