Range: -3.8 to 199.9°F / -19.9 to 110.0°C Resolution: 0.1° Accuracy: ±1°C (0 to 25°C); otherwise ±1.5°C (standard model) ±0.5° C at tested points; otherwise ±1.5°C (Ultra™ model) Update Rate: ~30 seconds

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 ±1.5° C.

DiSpLaYinG °f oR °c

1. Remove the clear rubber cap from the bottom of the unit to expose the °F/°C button.

2. Each press of the °F/°C button toggles the display between °F and °C.

3. With the desired unit of measure appearing on the display, replace the rubber cap to insure the thermometer remains water resistant.

MoUntinG tHe Unit

Most refrigerators have varying internal air tem

peratures, the unit should be placed as close as possible to the materials being observed.

Suction cup– Wet the suction cup with warm water. Apply to any clean smooth surface.

If the surface does not allow for the suction cup to hold, use the supplied Velcro® to mount the unit.

Velcro®– Remove the backing from one piece of Velcro®. Press the Velcro® rmly onto the suction

cup (the suction cup may atten). Remove the

backing from the second piece of Velcro the Velcro

rmly onto the selected surface for

. Press

mounting. Press the unit rmly into place.

aLL opeRationaL DifficULtieS

If this thermometer does not function properly for any reason, replace the battery with a new highquality 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.

If the unit is exposed to rapid changes in tem

perature, moisture may condense on the internal electronic components or on the display causing erratic, incorrect, or no readings on the display. To dry out the unit, open the unit by following steps 1 through 3 in the “Battery Replacement” section. Allow the unit to dry at room temperature for 24 hours. Close the unit by following steps 6 through 8 in the “Battery Replacement” section.

If the unit is exposed to temperatures below the range of the unit, the liquid crystal display may freeze, damaging the display.

BatteRY RepLaceMent

Erratic readings, a faint display, or no display, are all indicators that the battery must be replaced.

1. Remove the clear rubber screw covers from each side of the case.

2. Remove the two screws.

3. Lift the display from the bottom of the unit to expose the battery compartment.

4. Slide the battery out of the battery compartment.

5. With the positive “+” side facing up, slide a new

1.5V silver-oxide #357 battery in place.

6. Replace the bottom of the case.

7. Replace the screws and tighten securely.

not overtighten, this may damage the unit.

8. Replace the clear rubber screw covers so that the thermometer remains water resistant.
