thermometer can be used even when your hands are wet. The cover also keeps the unit
clean and dry.
Cautions
SK-1110 is not waterproof. Do not place it in water or use it where it may be splashed
with water. Otherwise, it will fail.
If water enters the vinyl cover, immediately turn off the unit. Make sure that no water
enters the cover while the unit is being used.
The measurement readings may become unstable if static electricity builds up inside the
vinyl cover while in use. If this happens, remove the vinyl cover and use the unit without it.
(1) Insert the unit fully into the cover, aligning
the display of the unit and (A) of the figure on
the right.
(2) Bend the (B) and (C) flaps to the unit side.
(3) Fold back the (A) part so that the cover
wraps around the upper and rear of the unit.

(2) If the MX/MN or AVG key is pressed while the OFFSET function is activated, the
maximum/minimum or average value is displayed on the lower display. Pressing the
OFFSET key again will release the OFFSET (REL) function. To release this, release the
MX/MN or AVG function first and then the OFFSET function.
Note: The OFFSET function is disabled when the maximum/minimum, average or memory
data is displayed.
Maximum or minimum value display function
The SK-1110 can display the highest temperature (maximum
value) or the lowest temperature (minimum value) measured
after the MX/MN key is pressed. During this time, the label "MX"
or "MN" is lit accordingly.
While the MAX/MIN function is active, the current temperature is displayed in the upper
display and the highest temperature or the lowest temperature is in the lower display.
To return to the normal measurement mode, keep pressing the MX/MN key for at least two
seconds.
NB. While the
MAX/MIN function is activated, the automatic power-off function is disabled.
The relationships between the maximum and minimum value display functions and the
MX/MN key operations are shown below:
