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 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 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.
