The PIR550 is a special thermometer that doesn't touch what it measures. It has different modes for measuring things using infrared technology. Remember, don't let children play with it, and don't use it for important safety stuff.
To check the temperature of something, point the thermometer at it using the lens (number 9) and press the Measurement button (number 7). The Distance to Spot ratio is 12 to 1, which means you need to be somewhat close. Make sure the thing you're checking is in the thermometer's view.
To access additional display functions, press the Mode button (2). This menu includes the emissivity setting, which defaults to 0.95. Press Mode (2), then use the Lock button (4) or ℃/ ºF button (3) to adjust the emissivity. Confirm the setting by pressing Mode (2). Emissivity can range from 0.10 to 1.
Press Mode (2) again to select modes like Maximum (MAX), Minimum (MIN), Difference between MAX and MIN (DIF), and Average (AVG). These modes display alongside their icons during measurement.
You can also set High Alarm (HAL) and Low Alarm (LAL) by pressing Lock (4) or ℃/ ºF (3), and confirm using the Measurement button (7). If the reading goes beyond these alarm limits, the respective icon will flash, and a beep will sound.
WARNING
STORAGE & MAINTENANCE Store at room temperature. The thermometer's sensor lens is delicate; maintain its cleanliness using a soft cloth or cotton swab with water or medical alcohol. Let the lens fully dry before use. Avoid submerging any part of the thermometer in liquid.
The thermometer provides visual alerts for different situations:
BATTERY REPLACEMENT
When the 'Low Battery' icon signals low power, replace the batteries promptly with AAA, 1.5V batteries. Important: Turn off the thermometer before changing batteries to prevent malfunctions. Properly dispose of used batteries and keep them out of children's reach.
Note on EMC/RFI: Readings may be affected if the unit operates within a radio frequency electromagnetic field strength of approximately 3 volts per meter, but the instrument's performance will not be permanently impacted.
