Welch Allyn Medical Diagnostic Equipment Thermometer 690 Manual De Usuario

The temperature switches to 

F or C scale by pressing and releasing the C/F button. The 

default temperature scale can be set to 

F or C in the biotech mode. A temperature must be 

displayed on the screen to switch between 

F and C.

This mode displays the most recently completed predicted temperature. 

Whenever the instrument is in Low Power or Pulse Timer mode, pressing and releasing the 
Recall button on the front panel will cause the most recently predicted temperature to display 
for 5 seconds. The unit will then automatically go into Low Power mode. 

Pulling the probe from the well in Recall mode will start a predict cycle.  To enter Biotech 
mode, hold the Recall button down and then pull the probe from the well.  Model 692 units 
must be in the wall holder to enter Biotech mode.

Pressing the Pulse Timer button on the Model 692 thermometer will interrupt the temperature 
recall function.

Note:  No Monitor mode temperatures are saved for recall. When a temperature is recalled, 

the mode in which it was obtained (Oral, Adult Axillary, Pediatric Axillary, or Rectal) is 
displayed, regardless of the current mode the thermometer is in.

This mode is used to set and check special features of the thermometer listed in Table 2-1. All 
Biotech mode settings are saved so they are not lost when the batteries are replaced.

1. Place the thermometer in the wall holder (Model 692 Only).

2. Press and hold the Recall button, while removing the probe from the probe well. Once the 

probe is removed, release the Recall button. 

3. Press and release the Recall button to move sequentially through the various program 

categories. Changes within each category are made by pressing and releasing either the 
Mode Selection or C/F button.

4. The Biotech mode control settings are stored in nonvolatile memory so that they are not 

lost when the batteries are changed. The Biotech mode will automatically time out after 5 
minutes of inactivity.

5. Replacing the probe into the probe well at any time will exit the Biotech mode and return 

the unit to normal operation.
