if the display should continue to appear for more than 3 seconds,

this will indicate overranging and measurement are not possible.

３Always remember to put the rubber plug back correctly atter zero

adjustments.

４Do not expose the photocell detector to excessive illumination when

it is not being used, as this will lead to deterioration of the meter

sensitivity. Always remember to cover the photocell detector when

the instrument is stored.

５Keep the photocell detector clean because light transmission will be

obstructed and will be reading errors.

Always wipe the surface clean with a soft and dry cloth, when the

detector is covered with dust and/or dirt.

could be damaged.

７Do not wipe the plastic instrument body with any chemical solution

such as acetone, ketone, thinner, etc., and do not expose the

instrument to temperature of more than 60℃

■OPERATIONS

１Take the instrument out of the soft carrying case.

２Put the photocell detector cover by hand completely so that no light

can reach to the detector.

Depress the measuring button for about two seconds.

Check whether the digital display is00.0and make sure that an

indication of low battery power …is not displayed.

３Take of the photocell detector cover and place the photocell detector

to the surface being measured to receive the incident light.

Then press the measuring button for about 2 seconds.

４When the digital display is stabillzed, release the measuring button.

Reading of the measurement on the display should be held or about

20 seconds for your easy reading and writing memo.

The power will be automatically off after 20 seconds.

５The measuring button has to be depressed while the previous

reading is being held, a new digital display will appear for the

illuminance of the incident light at the time.

６The hand strap on the instrument can be used for setting the

measuring distance. Unhooking one end of the strap and extending it

will work as scale for 30 centimeters.

If the strap is used without unhooking it, the strap can be utilized as

a scale for 15 centimeters.

■CAUTON

If the digital display does not become00.0in (2) above, zero

adjustment will be required. Detach the rubber plug on the rear surface

of the instrument. While depressing the measuring button, turn the
