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 ±1.0°C.
OPERATION
1. Extend probe to 45/90/135/180° to switch on the unit.
2. Press F/C button to select the desired temperature
