3. Other Notes:

(1) When measuring multiple areas with different scales and units, the scale and units must be reset each time.

(2) When data from multiple measurements are stored and subjected to summation or averaging, all the internally stored data are,

All calculations are performed after scaling according to the unit last set. The unit shall be the one last set.

Correct.

(3) To measure other areas without power loss, f must be used. 3 After clearing the memory information, perform the sum or average calculation.

VII. Instrument Power Supply Instructions:

When the instrument displays When the “LACK BATTERY” message appears, it indicates low voltage and the instrument cannot operate normally. Please use

The QCJ-2000 model is a dedicated power supply for charging. When operating indoors, measurement can be performed simultaneously with charging.

VIII. Precautions

● Do not store the instrument in high-temperature, humid environments.

● Handle the instrument with care to avoid severe impacts that could damage the sensor and other components.

● Restart the power supply or press the RESET button to initialize the instrument; the default input ratio is 1:1, and the unit is

in square centimeters, the memory is 0.

● When the instrument is stored for an extended period, charge the battery once every 60 days to prevent battery damage.

●When the instrument displays “S: OVER,” the measurement result has overflowed. Please enter an appropriate scale and unit, then remeasure.
