Operation
Turn Power ON or OFF
1. Press the button to turn power on or off. The meter will perform a short self-test
when turned on.
Light sensor
1. The light sensor is permanently attached to the meter. A coiled cable attaches the
sensor to the meter.
2. The white domed light sensor lens is a photo diode and resides underneath the
protective cap.
3. The meter automatically zeroes, therefore a zero calibration is not necessary.
4. The back of the sensor has a tripod mounting hole.
Taking light measurements
1. Remove the protective cap from the sensor and face the white domed light sensor
toward the source of light to be monitored. For overhead lighting, the sensor can be
placed on a desk or table top.
2. The light being measured must encompass the entire white sensor dome.
3. Read the light level on the LCD. If the light measurement is out of range an “OL”
indication will appear on the display. If the ‘OL’ appears, select another range by
pressing the RANGE button.
Selecting Lux or Foot candle units of measure
Press the
LUX
button to select lux units and the
fc

MX MN Function (stores/recalls highest MX and lowest MN readings)
Press the
MX/MN
button once to put the meter in MX mode. The meter will now display
only the highest reading (MX is displayed on the upper left-hand portion of the LCD). Press
MX/MN
again to put the meter in MN mode where the meter displays only the lowest
reading (MN icon is displayed). Press
MX/MN
again to have the meter continue to record
the highest and lowest readings but display only the current reading (both MX and MN
icons appear flashing), then use the
MX/MN
button to scroll through the highest and lowest
readings. To exit the MX MN mode, press and hold the
MX/MN
button until the MX and MN
