6. Measurements
(1) Connect the sensor probe(s) with a type "K"
thermocouple connector to the main unit.
Align the positive (+) and negative (-) sides of
the plug of the sensor probe with those of the
connector receptacle on the main unit. The
sensor probe SK-K010 provided as a standard
accessory is designed to measure a temperature within the range of -50°C to 300°C.
Make sure to use the probes within this range of measurement temperature.
NB. Be sure to use a type "K" thermocouple sensor and its proper connector. Do not use other
types of thermocouple sensor proves to ensure accurate temperature measurements.
(2) Press the PWR key to turn on the main unit.
Upon initial power-on of the SK-1120, the LCD displays all the elements for about one
second before the measurement mode starts.

All the elements are displayed
NB: When the sensor is not connected to the main unit, the LCD displays an "OL" or "-OL" to
warn that the sensor is overrange.
(3) You can avoid the influence of ambient temperature around the protection tube by inserting
the sensor probe into the target (regardless of whether gas, liquid or solid) to approximately
“ 15 times the diameter of the protection tube” from the end of the sensor protection tube
(approximately 35 mm for the SK-K010).
CAUTIONS
- Take care not to get burned when measuring high temperatures.
- The measurement accuracy may be affected when the ambient temperature is abruptly
changed. Allow the SK-1120 to acclimatize to the ambient temperature before starting the
measurements. When precision measurements are required and if the SK-1120 is brought
into an atmosphere with a temperature difference of 10°C or more, leave them in the new
atmosphere for at least 30 minutes before starting the measurements.
(4) Pressing the PWR key in the measurement mode turns off the main unit.
- - When first turning on the SK-1120, the LCD may display all the elements momentarily. This
is not a defect.
