Product Safety Instructions Before using the instrument, please read the following safety instructions carefully: (1)The temperature and humidity range of the normal working environment of the instrument is -30~65°C, 0~100%RH (non-condensing). If it is over the limited range while using, the instrument may be damaged. (2)The safe working temperature range of ordinary AAA alkaline batteries is -15~50°C. If the instrument needs to be used in an environment beyond this temperature range, it must be used with a suitable battery; if you have any questions, please contact the after-sales service department. (3)For precision instruments, please do not disassemble or repair without permission. (4)Please remove the battery if the instrument will not be used for a long time. ①LCD display ②Turn on/off , Record, Browse time ③Turn the screen on/off , View data , Mark ④External probe port ⑤External probe port ⑥External probe port ⑦External probe port ⑧Reset button ① ② ③ ④ ⑤ ⑥ ⑦ ⑧ Measurement Parameter Measuring Range Resolution Accuracy Response Time(t₉₀) Sample Interval Operation Temperature Storage Temperature Battery Capacity Battery Life Power Connector Size Case Material Protection Class -30~65°C 0.1°C 5 seconds -30~65°C ABS IP20 Memory Capacity Probe Model P1(Internal) -30~65°C Connection 2.

In addition, for models with Bluetooth, users can also choose to stop in the mobile APP. (2) When the number of recording points reaches the maximum limit, the recording will stop automatically. (3) If the battery is too low, it will automatically stop recording, save data and shut down. (4) The instrument can be stop recording while connected with PC or other equipment (non-adapter) during recording (NODATA function has to be turned off). 6.8 Query Max, Min, Average, High and Low Limits (1) When valid data is recorded (both probes record at least one reading or more), click the button in turn to query the maximum, minimum, average value and the high, low limit. (2) When there is no valid data recorded, click the button in turn to query the high and low limits. (3) After entering the query state, the icon disappears and the icon will be displayed. If there is no any operation for 10 seconds, or pressing any other buttons, it will return to the main interface. The icon disappears and the icon will be displayed. 6.9 Turn Off Buzzer Alarm When the instrument is over-limits, the over-limit indication or of the relevant channel will be displayed. If the time of the buzzer alarm has been set to a valid value, the buzzer will sound. Click any button to turn off the alarm bell. 6.10 Point Mark Operation When the instrument is in the recording state, enter the point marking interface, press and hold the button for 3 seconds to do point marking once, and it can mark 3 points maximum. 6. Quick Guide If there is no operation on the touch button for more than 15 seconds, the instrument will automatically lock and display the icon . If user needs to operate the instrument, must press and hold the button for 3 seconds to unlock it. When the buzzer of the instrument button sounds ”beep...” after the button is short-pressed or long-pressed by user, which means that the operation is valid. 6.1 Turn On When the power supply is restarted, the instrument will automatically turn on. 6.2 Turn Off When the battery power is too low, the instrument will automatically shut down (you must reconnect the power to turn it on). 6.3 Turn On Display When the display is off, press button 3 seconds to turn on the display. 6.4 Turn Off…
