■ Clicking: Each fast click indicates a rise to a higher temperature, similar to a radar detector.
Slow clicking indicates that the thermometer is still scanning, but not finding any higher
temperature.
■ To Retain or Lock Reading: The reading will remain on the LED display for 30 seconds after
button is released. If measuring room temperature, the temperature will remain on the LED
display for only 5 seconds.
■ To Restart: Depress the ON button to restart. It is not necessary to wait until the LED display
is clear, the thermometer will immediately begin a new scan each time the ON button is
depressed.
Alternate sites when temporal artery or behind ear are unavailable:
■ Femoral artery: slowly slide the scanner across groin.
■ Lateral thoracic artery: slowly scan side-to-side in the area - midway between the axilla and
the nipple.
15.3.4 Measuring Procedure
Measure only the side of the head exposed to the environment. Anything covering the area to be
measured (hair, hat, wig, bandages, etc.) would insulate the area, resulting in falsely high
readings.
Slide the thermometer straight across the forehead, not down the side of the face. Midline on the
forehead, the TA is about a millimeter below the skin, whereas at the side of the face, the TA is
much deeper, and measuring there would result in falsely low readings.
Wait about 30 seconds before measuring the same person again to avoid excessive cooling of the
skin.
An infant is frequently swaddled in blankets and clothing covering the neck area. Unless visible
sweating, one measurement at the TA area is typically all that is required. Should the user feel the
temperature is low, then push aside any clothing or blankets covering the neck area for about 30
seconds or so, and repeat the measurement on the neck behind the ear.
Factors That May Affect Measurement Accuracy
■ Sweating
When a fever resolves, the body may bring its temperature down by sweating. The temp scanner
detects this reduction in temperature immediately. However, sweating also causes extra cooling
of the skin. As a result the reading given by the temp scanner may be low. The user should
therefore either wait until the sweating has stopped (wiping of the forehead is not recommended,
since the sweating immediately begins again), or use the following method:
1. Scan the temperature as normal, keeping the button depressed;
2. Gently nestle the temp scanner on the neck directly behind the ear lobe;
3. Release the button and read the temperature.
The artery behind the ear lobe does not provide a sufficiently accurate reading. However, this
area is less affected by sweating than the forehead. In addition, during sweating, increased blood
flow produces higher skin temperatures, equivalent to TA temperature, resulting in a good
reflection of body temperature.
