OPERATIONAL CHARACTERISTICS
INTRODUCTION
Note:
This manual describes both the Model 670 and the Model 675 thermometers. The bulk of the
discussion is equally applicable to both products. Where there are differences, it will be noted as to which
instrument the discussion applies.
The Welch Allyn Model 670 and 675 Thermometers are the next generation of thermistor based medical
grade thermometers providing the accuracy and ease of use of thermistor technology as in the well known
Model 600, with enhancements in speed and features. Model 670 provides a Normal mode oral temperature
in about 10 seconds. Model 675 provides this temperature in about 4 seconds. These are significantly faster
than the typical 30 to 40 second average time to temperature in earlier products. Several other features
have been added, including a temperature recall feature, probe type display, displayed error codes for more
information when operation is abnormal, and a biotech mode to allow further investigation of some internal
parameters without the need for disassembly.
