2. PREPARATION FOR USE
General Information
The OMEGA HH931T and HH932T Data Thermometers are high-accuracy handheld digital
thermometers that provide accurate temperature readings in a wide range of manufacturing
and service applications. With wireless communication to your mobile device and the OMEGA
Data Cloud™, maintaining a record of your critical temperature data is easier, more efficient,
and more accurate than ever before. These full-featured, durable, and versatile instruments
simplify the process of temperature measurement through an intuitive user-interface. They
are compatible with eight NIST-traceable thermocouple types: B, E, J, K, N, R, S, and T.
Feature Overview
•Data collection, storage, and analysis via OMEGA Data Cloud
•Two-way communication and control with the OMEGA Thermometer Link™ mobile
app for Android™ and Apple mobile devices
•Bluetooth®low energy wireless technology
•Internal storage of up to 1000 measurements with time stamp
•1000-hour battery life1
•Four (4) digit dual LCD with LED Backlight
•All eight (8) NIST-traceable thermocouple types: B, E, J, K, N, R, S, and T
•Comprehensive real-time statistics: MIN, MAX, AVG, RNG, STDEV, and T1-T22
•Easy to clean
•Probe offset function to minimize probe error
•0.1° / 1 ° display resolution
•°F, °C, and K temperature units
•Reading HOLD mode
•Conforms to ITS-90 thermocouple tables
•Durable: Meets MIL-PRF-28800F, Class 2 requirements
•Tilt Stand/Magnet/Hanger
1Typical battery life under normal use conditions in laboratory environment. Continuous or repeated use of
features such as the backlight, maintaining an active Bluetooth connection for extended periods, or use or
storage at high or low temperature extremes may reduce battery life.
2T1-T2 is available on model HH932T only.

Safety Notices and Information
Symbols and Terms
Safety Notices denote hazards. They indicate an operating procedure, instruction, or practice
that, if not correctly performed or followed, could result in damage to equipment, or injury or
death to personnel. Do not proceed beyond a Safety Notice until all conditions and instructions
are fully understood and complied with.
WARNING WARNING denotes a hazard that could result in injury to personnel or death.
CAUTION CAUTION denotes a hazard that could result in damage to the unit or other equipment.
REMINDER denotes important information about instrument functions, menus, and
measurements.
Instrument Safety Notices
WARNING
MAINTENANCE INSTRUCTIONS WITHIN THIS MANUAL ARE FOR USE BY QUALIFIED SERVICE PERSONNEL
ONLY. DO NOT ATTEMPT TO SERVICE THIS UNIT UNLESS YOU ARE QUALIFIED TO DO SO.
SHOCK HAZARD
Disconnect all temperature probes and turn the unit off before removing the battery cover.
Never connect thermocouple leads to any source where more than 42 Volts (peak) could exist
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
could expose users to elevated potentials.
EXPLOSION HAZARD
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.
Never use this instrument or any temperature probe or sensor inside a microwave oven.

Preparation for Use
2-3
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
damage or personal injury could result from exceeding a probe’s maximum temperature rating.
CAUTION
RISK OF INCORRECT READING
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.
RISK OF INSTRUMENT DAMAGE
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 selected 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
care to avoid static discharge when handling the instrument or connected probes.
