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.
OPERATION
1. Remove the protective sheath.
2. Press the ON/OFF button to turn the unit on.
3. Press the °F/°C button to toggle the display
between displaying °F and °C.
4. Insert the stem of the thermometer into the
material to be measured.
To use the protective sheath as a thermometer holder,
slide the stem of the thermometer through the hole
located at the end of the sheath.
5. Press the ON/OFF button to turn the unit off.

when not in use.
6. Replace the protective sheath.
ALL OPERATIONAL DIFFICULTIES
If this thermometer does not function properly for
any reason, replace the battery with a new highquality battery (see “Battery Replacement” section). Low battery power can occasionally cause
any number of “apparent” operational difculties.
Replacing the battery with a new fresh battery will
solve most difculties.
BATTERY REPLACEMENT
Erratic readings, a faint display, or no display, are
all indicators that the battery must be replaced.
Use a screwdriver to remove the battery cap by
turning the cap counter-clockwise approximately
1/4 of a turn. Turning the cap further than 1/4 of a
turn may damage the cap. Replace the exhausted
battery with a new 1.5 volt, silver oxide, size 393
battery. Make certain the positive (+) side is visible.
Replace the battery cap by turning the cap clockwise approximately 1/4 of a turn. Turning the cap
further than 1/4 of a turn may damage the cap.
