1. INTRODUCTION
Compact and portable, your new meter can be used to monitor light levels
or check the LUX level of a particular light source. The sensor’s exclusive
photo diode and color correction lter meets the C.I.E. photopic spectrum
with a cosine correction factor meets the standard. Sper Scientic light
meters are cosine corrected for a quick and accurate response. Large
easily legible LCD. The meter has an external zero adjustment, data hold,
low-battery indicator, and a moisture resistant front panel. Comes with soft
carrying case, detachable light sensor, photo-sensor cover, instructions
and a 9-Volt battery.

3. MEASUREMENT PROCEDURES
• Insert the SENSOR plug into the SENSOR INPUT socket.
• Turn the meter on using the ON button.
• Remove the lens cap from the PHOTO SENSOR.
• Press the 1X button for measurements of 0 to 1999 LUX, or select
the 10X button for measurements of 2,000 to 19,990 LUX. If you are
uncertain about which range to use, select the highest range.
In 10X mode, “ “ appears in the right bottom LCD.
• Range Overload is indicated when “1” appears on the left side of the
display. If this occurs, switch to the highest range or discontinue use.
• Point the PHOTO SENSOR toward the source and read the results
on the display. To convert LUX results to FC, multiply the meter
reading by the factor of .0929
• Push the HOLD button to freeze the reading in the display. The word
“HOLD” is displayed. Press the HOLD button again to exit this function.
• Press the OFF button to turn the unit o󰀨.
NOTES:
• Keep the lens cap on the PHOTO SENSOR at all times except when
actually taking a reading.
• Fluctuations in the reading are generally due to shadows or
uctuations in the line voltage. Ambient temperature, drafts and
ventilation also a󰀨ect the luminous ux output.
• Avoid range overload and do not store in areas of high temperature
and/or humidity. Remove the battery for long-term storage.
4. ZERO ADJUSTMENT & CALIBRATION
• With the sensor cover securely in place and the meter turned on, the
LCD display should indicate “0000”. A slight variation will not a󰀨ect
readings; however, if a precise reading is required you may use the
ZERO SETTING terminal to reset the unit.
• To make an adjustment, cover the PHOTO SENSOR and press
the 1X button.
• Use a small screwdriver to turn the ZERO SETTING terminal until
“0000” is displayed.
• To maintain accuracy, annual laboratory calibration is recommended.
WARNING: Only use the terminal marked "ZERO" for adjustment.
The unmarked terminals are for professional laboratory calibration only
and tampering with these terminals will result in inaccurate readings
and require professional calibration of the meter.
