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,

Display will show zero value.
