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 Preparation for Use Unpacking and Inspection Each instrument is electrically and mechanically inspected before shipment.

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. CONFIGURATION DESCRIPTION Measurement data stored on thermometer Data Thermometer Limited to 1000 stored measurements Saved measurement data is reviewable on the thermometer Measurement data is stored on mobile device Data Thermometer + OMEGA Thermometer Link Number of stored measurements limited by available memory on the mobile device Real-time measurement monitoring When connected, any data stored in the thermometer internal memory is automatically uploaded to mobile device Data Thermometer + OMEGA Thermometer Link + OMEGA Data Cloud Measurement data stored on OMEGA Data Cloud Measurement data can be reviewed, analyzed, and downloaded from the OMEGA Data Cloud When connected, any data stored in mobile device memory is automatically uploaded to the OMEGA Data Cloud Figure 10: Data Collection Configurations Measurement Acquisition Interval The measurement acquisition interval determines the time interval between saved measurements while in automatic data collection mode. The minimum acquisition interval is 1 second when storing data to the instrument’s internal memory. When connected to the OMEGA Thermometer Link mobile app, the minimum supported acquisition interval is 5 seconds. See Section 3.3, Setup Menu to set the measurement acquisition interval. Real-time measurements, trend indicators, and statistics collection are unaffected by the acquisition interval. 3-11 Operating Instructions Internal Memory Up to 1000 measurements may be saved directly to the instrument, including both automatically and manually saved measurements. Once 1000 measurements have been saved, each new saved measurement will replace the earliest measurement stored in memory. When the instrument is connected to the OMEGA Thermometer Link mobile app, measurement data saved in instrument memory are automatically uploaded to the mobile device and removed from the instrument. Manual Measurement Storage Press to manually save the current temperature data and time/date stamp. If the instrument is not connected to OMEGA Thermometer Link, the saved measurement data will be stored in the instrument’s internal memory. When connected to the mobile app, existing saved data and new saved measurements are automatically transmitted to the mobile device and cleared from the instrument memory. To avoid data loss, periodically connect to OMEGA Thermometer Link whenever possible to upload saved measurement data to the mobile device or OMEGA Data Cloud.
