The digital illuminance meter is a precision instrument used tomeasure illuminance (Lux, footcandle) in the field.

It is meet CIE photopic spectral response. It is fully cosinecorrected for the angular incidence of light.The illuminance meter is compact, tough and easy to handle

owing to its construction.The light sensitive component used in the meter is a very

stable, long-life silicon photo diode and spectral response filter.

Main features of the LXP-1 device are the following:

Light-measuring levels ranging from 0,1Lux0,1kLux(0,01FC0,01kFC).

High accuracy and rapid response.

Data-hold function for holding measuring values.

Unit and sign display for easy reading.

Automatic zeroing.

Meter corrected for spectral relative efficiency.

Correction factor need not be manually calculated for non-standard light sources.

Peak-hold function for tracing the peak signal of light pulse withleast duration 10s and keep it.

Capable of selecting measuring mode in Lux or FC scalealternatively.

Auto power off (15minutes) or disable AUTO power off.

Maximum and minimum measurements.

Relative reading. Easy to read large backlit display

USB output connect with PC.

4 Level ranking.

99 values in memory that could be read on the meter and PC.

16000 values records datalogger.

System requirements:Windows 2000, XP or Vista

Minimum hardware requirementsPc or notebook, 90MHz Pentium of faster, 32Mb Ram,At least 5Mb free hard disk space screen resolution800600.

6.1 Connection

Switch the light meter on.

Plug the other end of the connecting cable to serial interface ofthe PC (USB).

Plug the USB line connecting cable 13,6mm jack plug into themeter socket.

Start the light meter software.

Selecting the COM.(Note: You should better switch the light meter on before you

plug the USB line connecting cable 13,6mm jack plug into themeter).

6.2 Installing the software

Fig. 2 Display in the program.

If the connection is not in order, the message OFFLINE orNO CONNECTION appears on the screen.

7 Battery check-up & replacement

Attention:When making measurements with a battery's mnemonic on,one must take into account additional indefinitemeasurement uncertainty or unstable working of the meter.

As the battery power is not sufficient, LCD will display lowbattery, and replacement of one new battery is required.

After turning off the meter, open the battery cover.

Disconnect the battery from the instrument and replace it with astandard 9V battery and go for the cover.

8 Maintenance

The white plastic disc on the top of the detector should be

cleaned with a damp cloth when necessary.


15/17

13

Do not store the instrument where temperature or humidity isexcessively high.

The reference level, as marker on the face plate, is the tip of thephoto detector globe.

The calibration interval for the photo detector will vary accordingto operational conditions, but generally the sensitivity decreasesin direct proportion to the product of luminous intensity by theoperational time. In order to maintain the basic accuracy of theinstrument, periodic calibration is recommended.

9 Storage

In the case of storage of the device, the followingrecommendations must be observed:

Make sure the meter and its accessories are dry.

In the case the meter is to be stored for a prolonged period oftime, the batteries must be removed from the device.

10 Dismantling and utilization

Worn-out electric and electronic equipment should be gatheredselectively, i.e. it must not be placed with waste of another kind.

Worn-out electronic equipment should be sent to a collectionpoint in accordance with the law of worn-out electric and electronicequipment.

Before the equipment is sent to a collection point, do notdismantle any elements.

Observe the local regulations concerning disposal of packages,

worn-out batteries and accumulators.
