[HI AL] key: high temperature alarm setting. 2. [LOW AL] key: low temperature alarm setting. 3.【AL UP】key: high/low temperature alarm on/off. 4.【℃/℉】key: ℃/℉ switch. 5. [HOLD/ON/OFF] key: Turn on/off or "HOLD" to lock the current temperature. Instructions 1. Press the [HOLD/ON/OFF] key: power on, the LCD will display in full, and then the measured temperature value will be displayed; press this key again to enter the data hold function, display "HOLD", press again to cancel the hold function. Long press this button for 4 seconds and then release the switch. 2.【℃/℉】key: press this key to switch ℃/℉ display. 3. Alarm setting: A: In the normal temperature measurement state, press the [HI AL] key to enter the high temperature setting interface, with a "HI" display sign. Press [AL UP] to turn on or off the alarm function, press [HI AL] for two seconds to enter the high temperature setting, the setting item flashes, press [AL UP] to adjust the value, long press [AL UP] for quick adjustment, set the value Then press [HI AL] to confirm. B: In the normal temperature measurement state, press [LOW AL] to enter the low temperature setting interface, with a "LOW" display sign. Press [AL UP] to turn on or off the alarm function, press and hold [LOW AL] for two seconds to enter the low temperature setting, the setting item flashes, press [AL UP] to adjust the value, long press [AL UP] for quick adjustment, set the value Then press [LOW AL] to confirm. C: Alarm temperature setting range: -50~200℃ (-58~392℉) (H-9269) or -50~300℃ (-58~572℉) (H-9283). D: Alarm mode 1. Separately enable high temperature alarm (HI): when the temperature is higher than the set value, it will output a high level, the "HI" symbol will flash and display, and the alarm will sound at the same time. Press any key to stop the ringing. 2. Separately enable low temperature alarm (LOW): when the temperature is lower than the set value, it will output a high level, the "LO" symbol will flash, and the alarm will sound at the same time. Press any key to stop the ringing. 3. Enable high/low temperature alarm at the same time (HI/LOW set at the same time): When the temperature exceeds the high/low temperature set temperature range, it will output high level, the symbol will flash, and the alarm will sound at the same time (when HI is set first, LO must be low The setting value for HI is valid. If the LO setting value is greater than or equal to the HI value, the previous HI setting value is invalid and needs to be reset).
