OPERATION:
• Turn the Checktemp 2on
by pressing the ON-
OFF switch located on
the front.
• Dip the Checktemp 2
probe into the sample
without exceeding the
maximum immersion
level.
• Stir gently and wait for
a few seconds until
the display stabilizes.

CALIBRATION
CHECK DEVICE (CCD):
Beneath the battery compartment
cover there is a CCD switch.
When activated, the circuit will send
a signal to the LCD requesting a
0.0°C (32.0°F) reading. The
Checktemp 2 should display 0.0°C
±0.3°C (32°F ±0.5°F). This assures
the user that the reading is reliable
and accurate.
BATTERY REPLACEMENT:
When the Checktemp 2 cannot be
switched on or the display fades,
pull out the battery compartment (af-
ter unscrewing the screw under-
neath the battery clip) and change
the 1.4V battery, paying attention to
the polarity.
Batteries should only be replaced in
a safe area using the battery type
specified in this instruction manual.
