Introduction

The DLM2 is designed to measure light levels in foot-candles or lux 
over 3 ra n g e s .

Features include

• 0 - 5000 foot-candles 
• Over 3 lux ranges
• Accurate to ±5% with a 0.4 second sampling rate
• Easy to read LCD display

Operating Instructions

Measuring Procedure

1. Slide the “

OFF/ON

” switch to the “

ON

” position.

2. Determine lux or foot candle (FC) on the “

LUX/FC

” switch.

3. Select the maximum range on the “

RANGE

” switch.

4. Hold the “

Light-Sensor

” by hand and face the measuring light 

oppositely. The display will show light values directly.

Measuring Consideration

1. As the rang B (2000 - 19990 LUX, 200 - 1999 FC) is designed and 

to measure the light values 

2000 LUX (200 FC). So if the 

measured light values are less than 2000 LUX (200 FC), select the 

RANGE

” switch to the lower range to get high resolution and 

precision. Otherwise the display may show some value readings 
but may not be correct.

2. As the range C (20000 - 50000 LUX, 2000 - 5000 FC) is designed 

to measure the light values 

20000 LUX (2000 FC). If the 

measured light values are less than 20000 LUX (2000 FC), select 
the “

RANGE

” switch to the lower range to get high resolution and 

precision. Otherwise the display may show some value readings 
but may not be correct.
