PRODUCT INTRODUCTION

• Illuminance in Lux or FC

• Color temperature and correlated color temperature

• Custom reference value of color di󰀨erence

Enables precise measurement of illuminance, color

temperature, correlated color temperature or color di󰀨er-

ence simultaneously shown on a backlit display. Excellent

for art galleries and museums, lm and TV studios, lighting

manufacturers, stores and designers. Meets CIE photopic

spectral response and color temperature. Lux and foot

candle selectable with general or LED light modes and a

hold function. Comes in a protective foam lined carrying

case complete with a tripod screw, magnetic mount, 9V

battery and instructions. N.I.S.T. traceable certicate of

compliance available (for lux and foot candles only).

Dimensions: 5 ½” x 2” x 1” (140 x 49 x 29 mm)

SAFETY INFORMATION

Read the following safety information carefully before at-

tempting to operate or service the meter. Only qualied

personnel should perform repairs.

Safety Symbols

CE Certication.

This instrument conforms to the following standards:

EN61326: Electrical equipment for measurement, control

and laboratory use.

IEC61000-4-2: Electrostatic discharge immunity test.

IEC61000-4-3: Radiated, radio-frequency, electromagnetic

eld immunity test.

IEC61000-4-8: Power frequency magnetic eld immunity

test.

Tests were conducted using a frequency range of 80-

1000MHz with the instrument in three orientations. The

average error for the three orientations is ±3% at 3V/m

throughout the spectrum.

However, between 180-500MHz at 3V/m, the instrument

permissive loss of performance is specied by the

specications.

Restrict to use of six substances within electrical and

electronic equipment (EEE), thereby contributing to the

protection of human health and the environment.

Precautions

Be sure to adhere to the following points to avoid injury.

• Please read the manual carefully to ensure safe and

correct use of this meter before using. Please reread if

necessary.

• Do not press, push or strike the LCD and sensor head.

• Do not use the meter in places where ammable or

near re.

• Do not use this meter in environments outside the

range of: 32ºF (0°C) to 122ºF (50°C) at Relative

Humidity no higher than 80%.

• When not in use, close the receptor cover.

• Be aware the accumulation of irradiations would cause

the sensor continue to age. Please keep away the light

source and cover with the cap when the unit is not in use.

• If the meter will not be used for a long time, remove the

battery and close the receptor cover.

• Never use organic solvents to clean the meter. (such

as thinner, benzene, etc.)

OPERATION INSTRUCTION

Main Function

Power On/O󰀨

Press and hold the Power button for 2 seconds to turn the

meter on and all of symbols will appear for 2 seconds on

the LCD. After power-on, the meter will measure and show

the readings on the LCD continuously. Press and hold the

Power button for 2 seconds again to turn the meter o󰀨.

Measuring Units

Press the button to select the illuminance (Ev) unit:

Lux (lx) or foot-candle (fcd).

Measuring light source selection(522)

After power-on, select the type of light sources to be

measured.

In the CT or CT display mode, press button

for 3 seconds to select di󰀨erent light source three dif-

ferent light sources can be selected: FL(Fluorescent),

INC(Incandescent) and LED.

The CT value will be more accurate when the selected light

source corresponds to the light source is being measured.

“----”, indicates that the measured CT value exceeds the

light source’s dened value. Please select a di󰀨erent light

source mode.

Data Hold

While measuring, press the HOLD button once to freeze

the display. HOLD will appear on the LCD. Press HOLD

button again to resume measuring.
