5. Measurement Results
5.1 Room Temperature Measurement
This device may be used to measure room temperatures between 32 ˚F and 89.5 ˚F, as
well as 108 ˚F to 212 ˚F. This corresponds to 0.0 ˚C to 32 ˚C and 42.2 ˚C to 99.9 ˚C.
To measure the room temperature press the ear button once while remaining at least
3 ft / 1 meter space between the sensor and any object.
5.2 Out-of-Range Temperatures
Temperature measurements that are outside the measurement ranges will result in
error codes L ˚ or H ˚ on the display, accompanied by beeps and the display lighting
red for three seconds. “L ˚” indicates that the measurement is below 32 ˚F, or 0 ˚C.
“H ˚” indicates a measurement exceeding 212 ˚F, or 100.0 ˚C.
