supply voltage drops, blinking “BT” appears in the display. If

this happens, please replace the battery with new one.

Data Hold button (Also used as the protection cover lock)

Push this button during measurement to hold the digital

current value and bar graph display. “DH” appears in

the display while the display data is held. Pushing this

button again releases the data hold function and causes

“DH” to disappear from the

display.

How to integrate the light sensor probe

with the main body for measurement

Insert the light sensor probe in the

position on the top left of the main body

as shown in the figure on the right.

How to open or close the protective cover

To open the protective cover, push

and hold the button on the left side

of main body into the direction

shown in the figure, and open the

Thank you for purchasing SANWA illuminance meter LX20.

Read this manual carefully before using the instrument for

safety use. Retain this manual together with the instrument

for future reference.

Be careful not to stain or damage the light sensor window.

If the light sensor window gets dirty, wipe lightly with a

soft, dry cloth.

Do not move the light sensor probe cord during

measurement, as this may result in variation of the

displayed value. Take special care not to move the cord

particularly during measuring low illuminance values.

This instrument incorporates the auto power save

function, which turns it off in 15 minutes after an

operation. To turn the instrument on after it has been

turned off by the auto power save function, set the

Range switch to OFF and keep it in the OFF position for

more than 1 second before setting it to another position.

Be sure to set the Power/Range switch to OFF after use.

This instrument is a pocket-sized illuminance meter

featuring excellent portability and operability.

It can be applied easily to a wide range of purposes

from brightness checking in daily life to illumination

maintenance in offices and factories as well as

illumination management in agriculture and forestry.

[1] Operating Precautions

[2] Applications

•

It is also possible to measure illuminance while the light sensor probe

is integrated with the main body.

After completing measurement, set the Power/Range switch to OFF.

When over range, displays “OL”.

The illuminance reference plane is located at the

top of the sensor as shown below illustration.

•

Insert a new battery without

mistaking the + and - polarity.

Attach the battery compartment

cover and clamp it with the screw.

The button-battery is made

of oxidized silver, etc.

Please keep it away from

little children lest they should swallow it in.

How to store the light sensor probe

The light sensor probe can be stored in the main body as shown below.

Fit the light sensor probe into the storage position so that the light

sensor window faces up.

Bend the cord and store it in the space on the right of the light sensor

probe.

Storage

The panel and case are little resistant to volatile solutions and heat. Do

not wipe the instrument using lacquer thinner or alcohol and do not

place it heat a source of high temperatures (soldering iron, for example).

Do not store the instrument in a place subject to vibrations or in a place

from it may drop.

Do not store the instrument under direct sunlight or in a place with low

temperatures, high humidity or condensation.

Be sure to remove the battery when the instrument is not to be used for

an extended period.

Batteris when the meter is shipped:

A battery for monitoring has been installed prior to shipment from the factory.

It may be discharged before the expiration of the described battery life.

*The battery for monitoring is a battery used to check the functions and

performance of the product.

Set a battery with its polarities facing in the correct directions.

Improved measurement accuracy by using a silicon

photodiode, which has a spectral sensitivity approximating

the relative luminous efficiency specified by CIE (Commission

Internationale d'Eclairage), in the light sensor.

Wide measuring range of 0.1 lx to 403.9 klx (403,900 lx).

Data hold function.

Auto power save function prevents wasting of battery power.

[4] Nomenclature

•

Easy-to-carry pocket size.

Separate, stick-shaped light sensor (window diameter 9

mm) from the main body enables measurement of a

narrow position or area. The light sensor can also be

integrated with the main body for measurement.
