How to use?

1) Press Power button to turn on

2) Press range selection switch to desired range.

3) Remove the photo detector cap and face it to UV light source, read the test value from the LCD display.

4) If the instrument displays “OL” on the LCD, then a higher range should be selected

5) Data-Hold mode: press the ‘HOLD’ key to select Data Hold mode, LCD display “H”, the reading is locked, press “HOLD” again to exit hold mode.

6) Peak-Hold mode: press the ‘PEAK’ key to select peak Hold mode, LCD display “PH”, the instrument displays new reading when higher UV light appears. Press “PEAK” again to exit peak hold mode.
