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 ac-
curacy as those found at the selected test points,
but will be within an accuracy of ±1 °C.
OPERATION
1. Press the ON/OFF button to turn the unit on.
Press the °F/°C button to switch between
Fahrenheit and Celsius.
2. Insert the probe into the material to be
measured and read the display.
3. Press the ON/OFF button to turn the unit off.
To conserve battery life, always turn the unit
off when not in use.

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” sec-
tion). Low battery power can occasionally cause
any number of “apparent” operational difculties.
Replacing the battery with a new fresh battery will
solve most difculties.
MAX/MIN MEMORY
1. To view the minimum temperature reached
since activating the unit, press the MAX/MIN
button. “MIN” appears on the display to indicate
the minimum temperature recorded.
2. Press the MAX/MIN button a second time,
within 3 seconds, to view the maximum
temperature reached since activating the unit.
“MAX” appears on the display to indicate the
maximum temperature recorded.
Note: Three seconds after pressing the MAX/MIN button,
the unit automatically returns to the current temperature
reading. (“MIN” and “MAX” are no longer displayed.)
3. Turn the unit off to reset the minimum and
maximum memories.

BATTERY REPLACEMENT
Erratic readings, a faint display, no display or
appearing on the display are all indications that the
battery must be replaced. Using a coin, turn the
battery cover on back of the unit in the direction of
the “open” arrow. Remove the exhausted battery
and replace with a new 1.5 volt silver-oxide 389
size battery. Make certain positive (+) side is vis-
ible. Replace battery cover.
