4. Temperature Measurement:

4.1 Ear Temperature Measurement, important – adhere unconditionally:

a. It is recommendable to measure 3 times in the same ear. If the

results differ take the highest value.

b. To avoid the risk of cross-infections you should clean the mea-

suring tip after every use as described under “Maintenance and

Cleaning”.

4.1.1 Gently pull the ear back to stretch the auditory

canal. (Fig. 4.1.1) Place the measuring tip

comfortably into the auditory canal. It has to

4.1.2 Press and hold the “SCAN” key till you hear a

beep. You can now remove the measuring tip

from the ear and read the measurement from

the display.

c. For healthy individuals, temperatures at different body parts can

vary by 0.2~1°C.

d. Clinical repeatability of readings: Deviation max. 0.23°C (<1 year

old), 0.22°C (1~5 years old), 0.21°C (>5 years old)

4.2 Temperature Measurement in Scan Mode:

4.2.1 When you press the “SCAN” key, the device will immediately show the

current temperature. Holding the “SCAN” key will update the tempera-

ture reading continually.

4.2.2 Possible applications: Temperature measurements of water, milk,

infections, you should clean the measuring tip after every use as

described under “Maintenance and Cleaning”.

5.3 Put the protection cap onto the device when you don’t use it.

How to measure the heartbeat pulse?

Use the stop watch to determine your pulse frequency. Also

see chapter 3.3 “Stop Watch”.

If you have counted 18 heartbeats within 15 seconds,

you can calculate that you have 72 heartbeats within one

minute.

Important!
