Ensure that the probe is suitable for the application, paying
particular attention to the temperature range and type of
thermocouple. Connect probe plug into the socket at top of
instrument ensuring correct polarity.

This is a function that gives an indicative reading within 14
seconds for poor thermal conductivity items. The use of this
function will reduce the accuracy to +/-2°C. For correct
SpeedRead measurements the probe must be in good thermal
contact with medium under test prior to activating the function. A
steep temperature gradient or wide temperature difference
between the initial probe temperature and item under test is
required. SpeedRead is suitable for core frozen food
measurements and hot/cold liquids. Good thermal contact is
unlikely when a general purpose probe is used on the surface of
food produce (not suitable for use with between pack probe).
Insert probe and press

Press
key to return to normal mode. If it is not possible to
obtain a faster reading due to the similarity of probe tip
temperature and temperature of item to be measured then the
symbol will be cancelled and the instrument will return to normal
mode.
