5.1 ການວັດແທກ
- ຊີ້ເຊັນເຊີອິນຟາເຣດໄປຫາວັດຖຸເປົ້າໝາຍ.
- Press and hold the measurement trigger. The display will show the real-time temperature reading.
- Release the trigger to hold the last measured temperature on the display (Data Hold). The device will automatically power off after a period of inactivity to conserve battery.
5.2 ອັດຕາສ່ວນໄລຍະຫ່າງຕໍ່ຈຸດ (D:S)
The MS 6520B has a Distance to Spot Ratio (D:S) of 10:1. This means that at a distance of 10 units from the target, the measurement spot diameter will be 1 unit. For accurate readings, ensure the target area is larger than the measurement spot size.
