2. Mode switching: there is a small hole on the back of the device
as shown in Figure 8. Use a 3mm diameter screwdriver to insert
the hole and press the button.
(1) Click to switch the temperature measurement unit, and C or F
will be displayed as shown in Figure 9 and figure 10. C is Celsius
and F is Fahrenheit.
(2) Press and hold for 3 seconds to switch the temperature
measurement mode. At the same time, the display of sur or BOD
or cou is as shown in Figure 11, 12 and 13. Sur is the surface
mode, BOD is the face mode, and cou is the counting mode.
