Sound level meter. Measurement Range Resolution
* Anemometer uses low-friction ball bearing mounted Temperature ( Type K ) -148 to 2372 ℉ 0.1 ℉
wheel design provides high accuracy. -100 to 1300 ℃ 0.1 ℃
* Light meter uses exclusive photo diode and color
correction filter light sensor, spectrum meets C.I.E. Measurement Range Accuracy
photopic. Temperature -148 to 2372 ℉ ± (1% reading + 2℉)
* Type K thermometer uses a standard type K (NiCr-NiAl) ( Type K ) -100 to 1300 ℃ ± (1% reading + 1℃)
thermocouple input jack suitable for all kinds of type
K probe. Anemometer ( Air velocity/Temp. )
* Humidity meter uses high precision humidity sensor
with fast response time. Measurement Range Resolution
* Sound level meter's characteristic is simulated as Air velocity ft/min 80 to 5910 ft/min 1 ft/min
" Human Ear Listing" response, used the " A " frequency m/s 0.4 to 30.0 m/s 0.1 m/s
weightings and " Fast " time weighting to meet IEC km/h 1.4 to 108.0 km/h 0.1 km/h
61672 class 2. MPH 0.9 to 67.0 mile/h 0.1 MPH
* Sound level meter can cooperate with the external 94 dB knots 0.8 to 58.3 knots 0.1 knots
sound calibrator and just press the front buttons to make Temperature 32 to 122 ℉ 0.1 ℉
the calibration ( Semiconductor) 0 to 50 ℃ 0.1 ℃
* Built-in microprocessor circuit assures excellent
performance and accuracy. Measurement Range Accuracy
* Concise and compact buttons arrangement, easy operation. Air velocity 80 to 5910 ft/min
* Memorize the maximum and minimum value with recall. 0.4 to 30.0 m/s <= 20 m/s : ± 3% F.S.
* Hold function to freeze the current reading value. 1.4 to 108.0 km/h > 20 m/s : ± 4% F.S.

Yes, I already received the item last Nov., and it's good. There's just an error sometimes need to remove the battery to restart it when it gets frozen.
Answer :
This should be the feature the guest boots into "REC," causing the host to fail to shut down
Just press the key "Max./Min," as shown in the video
"REC" will appear in the upper left corner of the screen. At this time, you can't turn it off by pressing the power button.
Press and hold "Max./Min." again, and the screen will shut down normally after the "REC" on the screen disappears
