-18°C to 0°C (0°F to 32°F): ±2.5°C (5°F)
0°C to 400°C (32°F to 752°F): ±2.0°C (4°F) or 2.0%
of reading, whichever is greater
For 2268-20:
-30°C to -18°C (-22°F to 0°F): ±2.0°C (4°F) + 0.1°C / 1°C
-18°C to 10°C (0°F to 50°F): ±2.5°C (5°F)
10°C to 550°C (50°F to 1022°F): ±1.8°C (4°F) or 1.8%
of reading, whichever is greater
*Assume ambient operating temperature of 23°C ±2°C
(70°F to 77°F)
Repeatability: ±0.8% OR ±1°C (±2°F)
(whichever is greater)

ASSEMBLY
Loading/Changing the Battery
1. Using a flat screwdriver,
rotate the battery door
lock to the unlocked
position and open the
battery door.
2. Connect one (1) 9V
battery to the connector
block. Fit the battery
into the compartment.
3. Close the battery door.
Turn the battery door
lock to the locked position.
Selecting Celsius or Fahrenheit
To set the temperature scale, pull the trigger and
then press the SET button three times. Press the
buttons above the up and down arrows to toggle
between °C and °F. Wait 5 seconds for the setting
to save and exit.
Setting the Laser Lock
To turn the laser on and off, pull the trigger and
then press the SET button four times. Press the
buttons above the up and down arrows to toggle
between ON and OFF. Wait 5 seconds for the set-
ting to save and exit.

Distance to Spot:
10:1 (2267-20)
12:1 (2268-20)
NOTE: A quick change
in temperature (>10°F)
affects the meter's read-
ings. Allow the meter to
reach ambient tempera-
ture before use (5 to 30
minutes, depending on
temperature change).
2267-20: At 5' away, spot is 6" in diameter
2268-20: At 5' away, spot is 5" in diameter
Scanning Object Temperature
1. Pull and hold the trigger for at least 2 seconds
and scan the surface temperature of an object.
A laser pointer is used for aiming on the area
being scanned.
NOTE: The object should be
larger than the spot being
scanned. If not, readings will be
affected. See Distance To Spot
for necessary object size.
2. As you continue to hold the
trigger, the icon
is displayed
along with the primary measure-
ment (surface temperature) and
secondary measurement (maxi-
mum, minimum, average, or dif-
ferential temperature) readings.
3. Release the trigger. HOLD is
displayed until the screen shuts off in about ten
seconds.
Setting the Trigger Lock
To turn the trigger lock on and off, pull the trigger
and then press the SET button five times. Press the
buttons above the up and down arrows to toggle
between ON and OFF. Wait 5 seconds for the set-
ting to save and exit.
Mode
MAX
Displays maximum temperature measured during a continuous reading
MIN
Displays minimum temperature measured during a continuous reading
AVG
Displays average temperature of last 20 measurements during a continuous reading
DIF
Displays the difference between MAX and MIN during a continuous reading
—— Center of Spot
– – – Laser pointer (approx. 3/4" above center of spot)
Spot size at distance indicated
2267-20 & 2268-20: At 1' away,
spot is 1.5" in diameter
2267-20: At 3' away, spot is 3.6" in diameter
2268-20: At 3' away, spot is 3" in diameter
OPERATION
Temperature Alarm
Press the ALARM button to turn on
the alarm function. The bell icon is
displayed. If the temperature read-
ing is outside the preset range, the
temperature reading will flash.
Setting Preset Range for the
Alarm
1. To set the alarm range, pull the
trigger and then press the SET
button. Repeat to toggle between
HI and LO settings.
2. Press the up or down arrow soft
keys to toggle between tem-
peratures. Wait 5 seconds for the
ranges to save and exit.
Low Battery
When the Low Battery icon is dis-
played, change the battery.
