ULTRA™ THERMOMETER ACCURACY
Ultra™ thermometers are tested at se-
lected test points to be within tighter than 
normal tolerances to assist in providing 
improved accuracy. Other points will not 
necessarily fall within accuracy as those 
found at selected test points, but will be 
within an accuracy of ±1.0°C.

protective sheath. Press ON/OFF button 
to activate. Press °F/°C button to switch

ture. Insert probe into the material to be 
measured and read display. 
MAX/MIN MEMORY
To view the minimum temperature reached 
since activating unit, press MAX/MIN 
button. “MIN” appears on the display to in-
dicate the minimum temperature recorded. 
Press MAX/MIN button a second time 
within 3 seconds to view the maximum 
temperature reached since activating unit. 
“MAX” appears on the display to indicate 
the maximum temperature recorded. 
NOTE:
Three seconds after pressing the 
MAX/MIN button, the unit auto-
matically returns to current sam-

Turn the unit OFF to reset max/min 
to current temperature.
ALL OPERATIONAL DIFFICULTIES
If this thermometer does not function 
properly for any reason, please replace 
the battery with a new high quality battery 
(see “Battery Replacement” section). Low 
battery power can occasionally cause 
any number of “apparent” operational dif-
ficulties. Replacing the battery with a new 
fresh battery will solve most difficulties.
BATTERY REPLACEMENT
The Lollipop™ thermometer displays a 
low battery indication, “
”, when it is
time to replace the battery.
Erratic readings, faint readings or no 
display are all indications that the battery 
must be replaced. Using a screwdriver, 
unscrew the three screws located on the 
battery cover on back of the unit. Remove 
the exhausted battery and replace with 
a new battery. Make certain the positive 
(+) side is facing you. Equivalent battery 
replacements are: RAYOVAC RW42, 
DURACELL D357, and EVEREADY 357. 
Replace the battery cover. Screw the 
three screws back into the unit. Do not 
over-tighten the screws as this may cause 
damage to the battery cover.
