OPERATIONAL CHARACTERISTICS
Introduction
The Welch Allyn 767 SureTemp is a wall mounted thermistor thermometer to be used for measuring
patient temperatures ranging from 84 °F to 108 °F (28.9 °C to 42.2 °C). Oral and rectal temperatures
are taken using Normal or Monitor operating modes. Axillary temperatures are taken with an oral
probe with the unit operating in the Axillary mode. In the Normal mode, the thermometer’s
microprocessor “predicts” body temperature in about 4 seconds for oral temperatures, about 15
seconds for rectal temperatures, and about 10 seconds for axillary temperatures. The Monitor mode
continuously displays the temperature of the probe which will reflect the patient’s actual temperature in
about 3 minutes and will continue for as long as the probe remains in place.
Basic System Description
The thermometer system consists of four main components: the external AC power supply, the
thermometer instrument, the probe, and the probe cover.
The M767 Thermometer can use either a Welch Allyn Model 767 domestic (120V 60HZ) or
international (230V 50Hz) Wall Transformer or a Welch Allyn Model 77305 AC Adapter for its external
AC power supply. These power supplies are available from Welch Allyn.
The main instrument’s operation is described below.
The Model 767 is easily connected to the Model 767 Wall Transformer. Two screws are used to
secure the Model 767 to the Model 767 Wall Transformer.
