Operational Characteristics

SureTemp

Model 678/SureTemp

Model 679 1-5

Normal Mode

After instrument and probe warmer self tests, the system is ready for use. Normal

mode operation is the rapid mode of temperature taking. This is the default mode and

is automatically selected when the probe is withdrawn from the probe well.

1. Upon withdrawal of the probe from its storage well, every segment on the display

will be illuminated. Watch for the display to change from the all segments test to

the probe type display; “OrL/Aly” or “rEC”, depending on the probe and algorithm

type , followed by

C or

F, whichever is selected. This display might take several

seconds to appear. At the same time that the probe type is displayed, a short

beep will sound.

2. At this point, load a probe cover and take a temperature.

To change between the Oral and the Axillary algorithms; place the instrument in

Ready mode as described above, and press the Mode button for approximately two

seconds. Observe that the display changes between “Orl” and “Aly” every time the

Mode button is pressed for more than two seconds.

Note:

It is possible that the display will switch from the probe type display to the

“walking segments” display and back again several times before the probe is

inserted in the mouth. This is acceptable operation and will not adversely

effect the temperature taken.

The thermometer will automatically switch to Monitor mode under some conditions.

These are:

•

If the prediction algorithm has not been activated for more than 60 seconds after

taking the probe out of the storage well.

•

If the instrument determines that room temperature is above 33.9

C (93.0

F).

•

If the thermometer is unable to predict an oral temperature after 15 seconds due

to improper technique such as excessive probe movement.

With correct use, the patient’s temperature will be displayed in about 4 seconds for

Model 678 and for Model 679. The instrument will beep to signal completion of the

Normal mode temperature cycle.

Note:

The thermometer reads the probe temperature immediately upon removal from

the storage well. If the probe was just placed into the storage well from a

previous temperature and immediately extracted, insufficient time may have

passed to allow the probe to cool to room temperature. This will result in the

instrument determining room temperature to be higher than actual. This could

result in the instrument switching to Monitor mode immediately if it detects

room temperature to be above 33.9

C (93.0

F).

For best results, the user

should wait at least 30 seconds between Normal mode temperatures.

If the probe is left out of the storage well after completion of a Normal mode

temperature, the unit will shut down after 30 seconds to conserve power. Simply

replace the probe in the storage well to prepare for the next temperature.
