Dr meter LX1330B Digital Light Meter

Instruction And Features

Instruction

The Digital illuminance Meter is a precision instrument used to measure illuminance in the special field such as construction, inspection, photography, greenhouse gardening and etc. It is fully cosine corrected for the angular incidence of light. The illuminance meter is compact, tough and easy to handle because of its construction. The light sensitive component uses a very stable and long life silicon diode to ensure stability with spectral response filter and fully corrected for the angular incidence of light.

Features

• Light-measuring levels ranging from 0.1 Lux to 200,000Lux, 0.01FC to 20,000FC.
• Highly accurate with precise and rapid response even in high ambient light.
• Data-Hold function for holding measuring values.
• Reading Display is arranged logically and clearly for ease and comfort of reading results.
• Automatic zeroing.
• Meter corrected for Luminous Efficiency function.
• Correction factor need to be manually calculated for nonstandard light sources.
• Short rise and fall times.
• Accessories:Carry case, instruction manual, battery(optional).

Name of Parts & Positions

1. LCD Display: 3-1/2 Digits with a maximum reading of 1999.
2. Power Switch: The power switch key turns the digital illuminance meter ON or OFF.
3. Data-Hold Switch: Pressing the HOLD key selects HOLD mode. When the HOLD mode is selected, the digital illuminance meter stops all further measurement. Pressing the HOLD key again cancels the HOLD mode, causing the digital illuminance meter to resume taking measurements.
4. Data-Peak Switch: Pressing the PEAK key again to clear the peak recording mode.
5. LUX / FC Unit Switch: Pressing the LUX / FC button to choose LUX or FC unit.
6. Range Switch: Pressing the range key changes
   • 200LUX / 20FC, 2000LUX / 200FC, 20000LUX / 2000FC, 200000LUX / 20000FC ranges,circularly.
7. Photo Detector.

Operating Instructions

1. Power-up: Press the POWER button 2 to turn on the meter.
2. Selecting the LUX / FC scale: Set the range selection switch button 6 to select the desired LUX / FC range.
3. Uncover the photo detector cap7 and face it to light source.
4. Read the illuminance result from the LCD display.
5. Out of Range: If the meter displays”l”in the left side of the display, that means the light source is too bright, so a higher range should be selected.
6. Data-Hold mode: Press the HOLD button 3 to select Hold mode. When the hold mode is selected, the illuminance meter stops all further measurements. Press the HOLD key again to cancel HOLD mode. Then it resumes normal operation and you can do the measurement again.
7. Data-Peak mode: Press the PEAK button 4 to select PEAK mode.When PEAK mode is selected, the illumiance meter stops all further measurements. Press the HOLD key again to cancel HOLD mode. Then it resumes normal operation.
8. When the measurement is completed, cover back the photo detector cap and turn the power selector OFF.

Battery Check-up & Replacement

1. When the battery power is not sufficient, LCD will display ” a’; then a new 9-volt battery is required to replace the old one.
2. After turning off the meter, open the battery cover by unscrewing the screw.
3. Disconnect the battery and replace it with a standard 9-volt battery and press the cover back into the place.

Spectral Sensitivity Characteristic

• To the detector, the applied photo diode with filiters makes the spectral sensitivity characteristic almost meet C.I.E.
• (INTERNATIONAL COMMISSION ON ILLUMINTION)

Maintenance And Recommended lumination

Maintenance

1. The white plastic dome on the top of the detector should be cleaned with a damp cloth when necessary.
2. Do not store the instrument where temperature or humidity is excessively high
