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 between
–20.0 and 100.0°C.

OPERATION

Slide the ON/OFF switch to ON to turn the unit on.
Slide the °C/°F switch to °F to display the tempera­ture in Fahrenheit or °C to display the temperature
in Celsius. Insert the probe into the material to be
measured. Slide the ON/OFF switch to OFF to
turn the unit off. Always turn the unit off when not
in use to conserve battery life.

NOTE: Both the probe and cable may be totally
immersed in liquid.

ALL OPERATIONAL DIFFICULTIES

If this unit does not function properly for any
reason, replace the battery with a new high-quality
battery (see “Battery Replacement” section). Low
battery power can occasionally cause any number
of “apparent” operational difficulties. Replacing
the battery with a new fresh battery will solve most
difficulties.

BATTERY REPLACEMENT

Erratic readings, a faint display, or no display are
all indications that the battery must be replaced
Remove the battery cap by turning it 1/4 turn
counter clockwise. Remove the exhausted bat­tery and replace with a new 1.5 volt silver oxide
battery. Make certain that the positive (+) side is
facing you. Replace the battery cap. Replacement
