DescriptionDescription
Product description
The infrared thermometer FlashBeam 8869 is a handy and precise de-
vice for contactless temperature measurements. It‘s features are:
• Laser sight
• Switchable between °C / °F
• Automatic Hold function
• Automatic switch-off
• Illuminated display
• Fixed emissivity
• Battery change indicator
Safety
• Use extreme caution when the laser beam is turned on.
• Do not let the beam enter your eye, another person’s eye or the eye
of an animal.
• Be careful not to let the beam on a reective surface strike your eye.
• Do not allow the laser light beam impinge on any gas which can
explode.
Operating elements
Operation
Operating element Description
Power ON/OFF The meter automatically powers when the
ON/HOLD key is pressed. Press the MEASU-
RE key to take a reading. Read the measured
temperature on the LCD. The meter powers
OFF automatically approximately 5 seconds
after the ON/HOLD key is released.
Selecting
Temperature units
(°C/°F)
Select temperature units (degrees C or F)
by rst pressing the ON/HOLD key and then
pressing the °C/°F key. The units will blink
on the LCD. Press the °C/°F key until the
desired units are shown on the LCD.
Data Hold This meter automatically holds the last tem-
perature reading on the LCD for ve seconds
after the ON/HOLD key is released. No extra
key presses are necessary to freeze the
displayed reading.
Backlite LCD Select backlite by rst pressing the ON/HOLD
key and then pressing the BACKLITE key.
Repeat the procedure to turn the backlight
OFF.

Measurement conditions
Holding the meter by its handle, point the IR Sensor toward the object
whose temperature is to be measured.
The meter automatically compensates for temperature deviations
from ambient temperature. Keep in mind that it will take up to 30
minutes to adjust to wide ambient temperature changes.
When low temperatures are to be measured followed by high tempe-
rature measurements, some time (several minutes) is required after
the low (and before the high) temperature measurements are made.
This is a result of the cooling process which must take place for the
IR sensor.
Battery replacement
A ashing display is the indication that the battery voltage has
fallen into the critical region (6.5 to 7.5 V). Reliable readings can be
obtained for several hours after the rst appearance of the low battery
indication. Open the Battery Compartment and remove the batte-
ry,then install a new battery and replace the cover.
