10. Memory Recall: Press the RECORD BUTTON. Use the RECALL

BUTTON (3-6, fig. 1) to recall the minimum and maximum readings.
With the REC symbol on the display, press the RECALL BUTTON (3-6,
fig. 1) once. The maximum recorded value will be displayed. The letters
“Max” will also appear, indicating that this is the maximum or highest
reading. A second press of the RECALL BUTTON will display the
minimum reading. The letters “Mm” will appear indicating that this is the
minimum or lowest reading.

NOTE: The Data Record function must be on to utilize the Memory recall
features. Once the RECORD BUTTON has been pressed a second time to
deactivate the data record function, the minimum and maximum values are
no longer stored.

COMPUTER INTERFACE
This unit features computer output. A COMPUTER OUTPUT SOCKET (3-11,
fig. 1) is located on the top of the unit. To utilize this feature, connect the unit
to a PC with an accessory Data Acquisition System. See ACCESSORIES.

BATTERY LIFE
If the letters ‘LBT’ appear on the left corner of the display, it indicates the
batteries are low and need to be replaced. To replace the battery, slide the
battery cover located on the back of the unit away from the unit. Remove the
old battery and replace it with a new 9-Volt alkaline battery. Use an alkaline
battery, NOT a regular or heavy duty battery. Properly connect the battery.
Replace the battery cover. Incorrectly installed batteries may damage
electronics.

The unit has an automatic shut off feature to prolong battery life. If no button
on the unit is pressed for ten minutes, the unit will automatically shut off. To
deactivate this feature, press the RECORD BUTTON while a measurement
is being taken.

LCD CONTRAST ADJUSTMENT
The Contrast of the LCD may need to be changed either because of light
conditions, battery voltage drop, or user preferences. The LCD contrast can
be adjusted using the LCD CONTRAST ADJUSTMENT KNOB (3-5, fig. 1).
Simply turn the knob to the left or right until the optimal LCD contrast is
obtained. If the display is filled with “88888” when no reading is being taken,
the contrast needs to be adjusted. Turn the contrast knob to the left until a
single “0” appears.

ALL OPERATIONAL DIFFICULTIES
If this Light Meter does not function properly for any reason, please replace
the battery with a new 9-Volt alkaline battery (see Low Battery section,
above). Low battery power can occasionally cause any number of “apparent”
operational difficulties. Replacing the battery with a new fresh battery will
solve most difficulties.
