ULTRA™ THERMOMETER ACCURACY
Ultra™ thermometers are tested at selected 
test points to be within tighter than normal 
tolerances to assist in providing improved 
accuracy. Other points will not necessarily fall 
within the same accuracy as those found at 
the selected test points, but will be within an 
accuracy of ±1° C.
ALL OPERATIONAL DIFFICULTIES
If this thermometer does not function properly 
for any reason, replace the battery with a 
new high quality battery (see the “Battery 
Replacement” section). Low battery power 
can occasionally cause any number of 
“apparent” operational diffi culties. Replacing 
the battery with a new fresh battery will solve 
most diffi culties.

BATTERY REPLACEMENT
Erratic readings, a faint display, or no display 
are all indicators that the battery must be 
replaced. To replace the battery, remove 
the three battery cover screws. Remove the 
battery cover. Replace the exhausted battery 
with a new 1.5-volt, silver oxide, #357 size 
battery. Make certain the positive (+) side 
is visible. Replace the battery cover and 
battery cover screws. Do not over-tighten the 
screws as this may damage the unit. 
NOTE: When replacing the battery cover, ensure 
the screws are tightened securely to maintain the 
unit’s water-resistance.
