SAFETY INFORMATION
Read the following safety information carefully before at-
tempting to operate or service the meter. Only qualied
personnel should perform repairs.
Safety Symbols
CE Certication.
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 specied by the
specications.
Restrict to use of six substances within electrical and
electronic equipment (EEE), thereby contributing to the
protection of human health and the environment.

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 dierent 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 dened value. Please select a dierent light
source mode.
