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.
2-2
Preparation for Use
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.
2-3

Measurement Data Collection Overview
The data collection features of the OMEGA Data Thermometers accurately record and store
accurate time stamped measurements at the touch of a button. Saved data can be reviewed
on the device, or uploaded to the OMEGA Data Cloud via the OMEGA Thermometer Link
mobile app.
Measurement data is collected automatically at user-programmed intervals, or manually as
desired by the user. All saved measurements can be viewed directly on the instrument,
monitored in real-time with the mobile app, or reviewed, analyzed, and downloaded from
the OMEGA Data Cloud.
Each saved measurement includes a time and date stamp based on the date and time
programmed into the instrument. Through the mobile app and OMEGA Data Cloud, data
collection sessions can be associated with user-customizable locations to establish an
auditable record for a given asset, product, batch, bin, etc.
Measurement Data Collection Configurations
Data collection can be accomplished using three distinct configurations to provide the most
flexibility and adaptability based on equipment availability and internet or cellular access.
3-10
Operating Instructions
If no compatible mobile device is available, measurement data may be collected and stored
directly on the Data Thermometer. To manually save a measurement, press
while the
measurement of interest is displayed. Up to 1000 time stamped measurements can be saved
directly to the instrument.
Measurement data may also be collected and stored via the OMEGA Thermometer Link
mobile app, without a connection to the internet and the OMEGA Data Cloud. Once
connected to OMEGA Thermometer Link, any saved measurement data stored on the
instrument is uploaded, and new saved measurements will be immediately transmitted to
OMEGA Thermometer Link. Transmitted measurement data is stored on the mobile device
and removed from the instrument.
When both a compatible mobile device and internet access are available, saved
measurement data can be uploaded to the OMEGA Data Cloud for long-term storage, review,
analysis, and download. See Figure 10 below.

UNCERTAINTY (2SIGMA)
Calibrated Thermocouple Cables with recorded correction values shall be used
throughout this procedure to adhere to the expanded instrument uncertainties provided
in Appendix B. Thermocouple Cables must be calibrated to the accuracies listed in the
Thermocouple Calibrator Specification column of Appendix A, or better.
Thermocouple
Cables
Thermocouple Cables are only required for each desired thermocouple type.
The thermocouple cables must be terminated at one end with a male miniature
thermocouple connector for connection to the UUT. The opposite end should be
terminated as appropriate for the thermocouple calibrator.
For two channel UUTs, a split or “Y” cable may be used, terminated with two (2) male
miniature thermocouple connectors. Correction values must be established for each leg
of the Split Thermocouple Cable.
Copper Mini-TC Cable is required for Voltage Gain and Offset alignment only. This cable
does not require calibration.
Copper MiniTC Cable
One end shall be terminated with a male miniature thermocouple connector for
connection to the UUT. The opposite end shall be terminated with copper connections
appropriate for the DC Voltage Source.
For two channel UUTs, a split or “Y” cable may be used, terminated with two (2)
male miniature thermocouple copper connectors.
Straightened
Paper Clip
Required to access the calibration enable switch. Any rigid wire, approximately 0.8
