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.
