1. INSTRUMENT CHARACTERISTICS

Luxmeter L-100 belongs to the family of RF-1xx devices (where xx is numerical designation). De-

vice structure is based on concept of separation device function onto probe with is complete meter and

user control unit which role is link user control device with probe. This concept of device allows operat-

ing with many probes with can have different metrological function. Under notion of metrological func-

tion includes here: detector spectral characteristics, number of measure ranges, dynamic range, unit of

physical quantity. Type of measure probe decides about complete measurement device function, so it can

be photometer or radiometer with arbitrarily defined spectral sensitivity. Control unit has defined list of

probes together it can operate and it has predefined maximal firmware version of probe with it can oper-

ate. It allows in easy way to evolve into both device types with backward compatibility into older ver-

sions.

Luxmeter L-100 is designed to work with measure probe type G.L-100. Radiometer-photometer

RF-100 with G.L-100 probe implements luxmeter function too.

Luxmeter L-100 fulfill recommendations of International Commission On Illumination (CIE),

published in publication no. 69-1987: „Methods of characterizing illuminance meters and luminance me-

ters: Performance, characteristics and specifications”.

Device was approved by Polish Central Office of Measures (decision no. RP T 02 196). Luxmeter

L-100 is designed for measurement illuminance in range from 0.001 lx to 300 000 lx, but after installing

proper adapter - for measurement luminance. There are three kinds of luminance adapters with different

field apertures: 1°, 3°, 10°.

Luxmeter L-100 fulfills requirements of EMC standards:

EN 61326 „Electrical equipment for measurement, control and laboratory use. EMC re-

quirements ”.

EN 61000-6-2 „Electromagnetic compatibility (EMC). Generic standards. Immunity standard

for industrial environments ”

EN 61000-6-3 „Electromagnetic compatibility (EMC). Generic standards. Emission standard for

residential, commercial and light-industrial environments ”

4. RESULTS PANEL

Results panel is main window of the meter. All bookmarks are hidden and there is no displayed message

on the screen. Results panel consists of measure window, logarithmic bar of measured value and status

bar.

4.1. Measure window

Measure window includes:

• measure state indicator:

pause,

run,

• range overflow indicator,

• measured quantity symbol:

illuminance

luminance,

luminous exposure (time integral of the illuminance),

time integral of the luminance,

• measured quantity value,

• measured quantity unit.

Besides:

for relative measurement mode: actual measured value (E) and reference value (E0) ,

for integral measurement mode: actual measured value (E) and integration time (t) in format

hours:minutes:seconds,

for statistics and integration mode: statistics field including: number of measures (n), minimum (min),

maximum (max), average (avg), minimum to average ratio (mn/a),

minimum to maximum ratio (mn/x).

In measured quantity unit field, before basic unit, multiplier can be displayed. Measured values displayed

in statistic field do not includes designation of basic unit. Only metric prefix corresponding to multipliers

are displayed:

• f (femto) = ×10-15

• p (pico) = ×10-12

• n (nano) = ×10-9

• µ (micro) = ×10-6

• m (mili) = ×10-3

• k (kilo) = ×103

• M (mega) = ×106

• G (giga) = ×1012

• T (tera) = ×1015

• P (peta) = ×1018

4.1.1. Measured quantity value format

Measured quantity value is displayed in measure window with fixed resolution, corresponding to set

measure range. In case when measure value is greater then 9999×LSB (where LSB is weight of less sig-

nificant bit), there is a clipping of showed number to four most significant digits. Position of decimal

point and unit multiplier are set to present result with best precision.

4.2. Measured value logarithmic bar

Measured value bar: is placed in upper part of the result screen. Bar is

displayed during illumination measure without relative measure or statistics option selected. It includes

scale that covers whole measuring range and strip of fulfillment. Doted part of scale covers lower range.

If strip of fulfillment is in this area it signifies, that measurement is possible with greater resolution on

lower range. Indicator is not refreshed during return from MENU to result panel.

4.3. Status bar

Current setup is displayed in lower part of meter’s screen. This status bar is divided into: measurement

range field, measure type field, change range control field, statistics field, memory field, battery indicator

field, alarm field, date/time field.

4.3.8. Date/time field

Current date and time is shown in lower right corner of a display. In case

when viewing measures from memory, this field displays date and time of

saved measure.

5. OPERATION

5.1. Menu

Menu contains three bookmarks: MODE, SETUP, MEMORY, which are selected through buttons:

. All bookmarks contains list of available options. User can change setup option by

changing the position of pointer (option displayed in negative) by arrows: and apply the setup value

by key . Menu items which have sub-menus are ended with three dots (expandable menu). Instrument

memorize last position of menu pointer.

Canceling is available using key .

Actual selected options are signalized on the list by checkout .

The messages that are shown during operation can be deleted by keys: or . Changing instru-

ment setup can be only made in pause mode. All setup values and positions of pointers in menus are

memorized and will be restored after power on.

5.1.1. Menu MODE

Instrument can operate in one of three modes:

−

−−

−single measure,

−

−−

−continuous measure,

−

−−

−integrating.

Additionally, for single or continuous measure relative measure option is provided (on/off type).

Fig. 4. Menu MODE with selected continuous measure option.

5.1.1.1. Single measure

Function: turns on single measure mode, other options stay unchanged.

5.1.1.2. Continuous measure

Function: turns on continuous measure mode, also turns on automatic measurement range control.

5.1.1.3. Relative measure

Function: turns on/off relative measure option.

–

10 –

After turning on this option, new window for setup reference value opens. Window contains last meas-

ured value by default for reference:

Edit can be made by passing numeric values directly from alphanumerical keyboard. Position of cursor

can be modified by key . Keys change multiplication factor of unit. Approving reference value

can be made by key . After that instrument change measurement range control to automatic. If that

option was selected during integrating mode, single measure mode is selected by the instrument.

5.1.1.4. Integration

Function: turns on integration mode.

Instrument loads last measures values after switching to this mode, so continuation of last integral meas-

urement is possible. Result value of actual illuminance is rewritten from last single or continuous meas-

ure. After leaving integrating mode (switching to single, continuous or relative measure), in the result

field instrument displays last measured value of illuminance during integral operation mode.

5.1.1.5. Integration-clear

Function: Clears measured integrated value and it's related statistics.

Instrument displays notice window: . After selecting YES and approving it by key me-

ter deletes measured integrated value and it's related statistic values.

5.1.1.6. Statistics...

Function: displays statistics sub menu:

−

−−

−Add measure - adding last measure to statistics.

−

−−

−Clear all - delete (after approving the notice window) statistics .

−

−−

−Auto add - appending data to statistics after every measure (on/off).

Statistic option only concern single and continuous measure. In integrating mode instrument make inde-

pendent statistical calculations.
