OPERATING INSTRUCTIONS

To power the meter on or off, press the green button.

Before making any measurements, remove the cap covering

the light sensor (Callout 7). Do not detach the cap from the

lanyard.

Begin by selecting a measurement unit—lux or foot-candles.

Pressing the Lx/Fc button (Callout 4) toggles between the two

units. When the DLM204 powers on, it automatically resumes

using the last unit selected. In other words, whichever

measurement unit you select becomes the meter’s default

unit until you change it.

To make an initial measurement, position the meter so the

light sensor is as close to perpendicular to the source of light

as possible.

If your reading is OL. or OL, there is enough light to overload

the meter using its current measurement range. You must

switch to a wider measurement range.

CHOOSING THE RIGHT RANGE

The DLM204 provides four manually selectable ranges for

each of the two measurement units: lux and foot-candles

(FC). Repeated presses of the R button (Callout 6) cycle

through the four ranges for each unit. The following two

graphics illustrate the sequence.
