Asphalt low-temperature extensometerPower on, the LCD screen displays the name, with a delay of about 4 seconds, displaying the work interface, including time, speed, value 1, value 2, value 3, and average value. The "cycle" button is a repeat button. Press it once to activate the water pump, press it again to deactivate the water pump, and press it again to activate the water pump again. So repeatedly.

After calculating the length of 3, the average value will be displayed on the screen. After the experiment is completed, you can press the "Save" button to save the time, length 1, 2, 3, and average value of this experiment. The low-temperature digital asphalt extensometer can store 20 sets of data for ten years. If the next experiment is required, press the "Experiment" button to start a new experiment.
Query saved data:
Press the "Set" button on the asphalt low-temperature extensometer, and the query record will be displayed on the screen.

If there is no record in the system, press the "→" key and it will display as 00:00 on 00:00, with lengths 1, 2, and 3 all being 00000. After finding a new set of data, press the "reset" button to delete this set of data. Once the data is deleted, it will never be retrieved. Please use the "reset" button with caution.
On this interface, press the "Settings" button to enter the [Date and Time Setting Interface]. After each data query, you must press the "Set" button to enter the [Date and Time Setting Interface], and then press the "Set" button to enter the experimental interface.
Date and time setting:
When on the asphalt low-temperature elongation tester experimental interface, press the "Set" button to enter the query record, and then press the "Set" button to enter the [Date and Time Setting Interface]. At this moment, a cursor appears on the screen. Press the "→" and "←" keys to move the cursor to the number that needs to be modified. Press the "" and "-" keys to add or subtract numbers.
