Operating Instructions
Light Sensor
1. The light sensor is permanently attached to the meter.
2. Remove the protective cap to expose the light sensor. When the
sensor's protective cap is removed, the light sensor will begin to
capture light.
Power On/Off
Press the Power button to turn power on or off.
Unit of Measure Selection
Press the Lux button to measure in lx units and the Fc to measure
in Foot-candles.
Measurement Range Selection
1. Remove the protective cap from the sensor. For overhead lighting,
the sensor can be placed on a desk or table top.
2. The display will indicate the light level in "Fc" or "Lux".
3. Press the RANGE button to select the range that provides the
maximum resolution. If the 'OL' appears the light measurement is
out of range. To scroll through the measuring ranges press the
RANGE button.
4. Press the Backlight button to illuminate the LCD display if needed.
MAX/MIN
Press the MAX/MIN button to display the Maximum and Minimum light
level values recorded during the measurement process.
1. Press the MAX/MIN button to enter the MAX/MIN function. The
"MAX" symbol will appear on the LCD display and hold only the
highest reading. The display will update only when a higher reading
is measured.
2. Press the MAX/MIN button. The "MIN" symbol will appear on the
LCD display and hold only the lowest reading. The display will
update only when a lower reading is measured.
3. Press the MAX/MIN button again. The "MAX MIN" symbol will
appear ashing and the meter will now display the current reading,
but will continue to record the highest and lowest values.

4. Press the MAX/MIN button again to toggle between "MAX" and
"MIN" displays.
5. To exit the "MAX MIN" mode, press and hold the MAX/MIN button
until the MAX and MIN symbols disappear.
Data Hold
Press the HOLD button to freeze the displayed reading. The "MANU
HOLD" symbol will appear on the LCD display. Press the HOLD button
again to resume normal operation. When the "Data Hold" function is
enabled the analog bargraph will continue to display level changes.
Peak Hold
The Peak Hold feature allows the meter to captures light pulses that rise
or fall down to 10μs.
1. Press and hold the PEAK button until "CAL" appears on the
LCD display.
2. Momentarily press the PEAK button. The 'PMAX' symbol will
appear on the LCD display. The meter will then measure and
display any light pulses. The display will hold the results until a
higher pulse appears.
3. Press the PEAK button again to display the "PMIN" values.
4. To exit the "Peak Hold" mode, press and hold the PEAK button until
the 'PMAX' or 'PMIN' symbol disappears.
Relative Mode
Measurements can be displayed as a difference between the measured
light level and a stored reference value.
1. To store a reading as a reference, press the REL button when the
desired reference measurement is on the LCD display.
2. All subsequent displayed readings will be "relative" to the stored
reference value. For example, if the reference value is 1000 and the
actual light level is 1250, the meter will display 250.
3. To view the reference value, press the REL button again so that
the "REL" symbol begins to ash. The displayed value will be the
reference value.
4. To exit the Relative mode, press and hold the REL button until the
"REL" symbol disappears.
