4. MEASURING PROCEDURE
4-1 Function selection/Measurement
1)Turn on the meter by pressing the " Power Button "
( 3-2, Fig. 1 ) momentarily.
* Pressing the " Power Button " ( 3-2, Fig. 1 )
continuously and > 2 seconds again will turn off the
meter.
2)The meter can select 2 kind function as :
a.UVC Light meter
b.Type K/J Thermometer
Pressing the " Function Button " ( 3-3, Fig. 1 )
continuously ( not release the button ), the Display
will show the following text in sequence :
C UVC Light meter
tP Type K/J Thermometer
Until the Display show the desired mode ( Function ),
just release the " Function Button " ( 3-3, Fig. 1 ), the
meter will execute this function with default.

UVC Light masurement
a.Set the function to the UVC light meter, refer to page 7.
b.Install the " UVC Probe Plug " ( 3-17, Fig. 1 ) into the
" Probe Input Socket " ( 3-7, Fig. 1 ).
c. Power on the meter by pressing the " Power Button "
( 3-2, Fig. 1 ). The display will show the " mW/cm^2 "
unit. Now the meter is ready for making the UVC
light measurement.
d.Use the fingers to hold the " UVC Sensor body " ( 3-18 ),
face the " UVC Sensor " ( 3-19, Fig. 1 ) against to the
measurement UVC light source directly. The display
will show the UVC light measurement value.
Zero adjustment :
During the UVC measurement, if blank the
UVC Sensor ( 3-19, Fig. 1 ) , the Display not
show zero value, press the " Zero Button,
Logger Button " ( 3-6, Fig. 1 ) > 3 seconds,
