2 Functions
QUESTempº II
The QUESTEMP
II consists of a belt or pocket worn electronic assembly with a thin flexible
cable leading up to a small earmold which contains the sensor and a small speaker for an
audible alert. The sensing device protrudes from the earmold and a disposable E.A.R.® foam
earplug slides over the sensor providing a comfortable vehicle for inserting and maintaining
the sensor. The speaker and earmold remain just outside of the ear to completely avoid any
possible damage or injury to the ear canal.
Functions
Ambient Compensation
Unique to the QUESTEMP
II, a second sensor, located in the earmold, will sense and
compensate for any non-drastic changes (less than +/-10
C) in the thermal environment.
This is necessary because changes in the thermal environment will have an effect on
the outer tissues of the body including the ear canal. By compensating for these
changes, error induced by the environment is notably reduced.
The earmold temperature is data logged and included in the printout as an indicator of
the changing thermal environment.
If the thermal environment changes drastically (greater than +/- 10
C), then the
QUESTEMP
II should be recalibrated in that environment.
Keypad Functions
A desired function is activated by simply depressing and releasing the
corresponding key. For the functions CAL, PRINT, CLOCK, PRINT
RATE, and ALARM LEVEL, when the key is pressed once the current
value or setting will appear in the display. Pressing the same key a
second time (consecutively) will allow that setting to be changed.
