Stressometer type ADTM 60
- Dimensions of the main case: 121 mm x 171 mm x 38 mm (about 4.7 x 6.7 x 1.5 inches).
- Dimensions of the accelerometric sensor: 130 mm x diameter 40 mm (about 5.5 x 2 inches).
- Connection of the sensor to the electronic circuit: with a 4-conductor coiled cord.
- Weight of the main case (including batteries): about 320 grams (0.7 pounds).
- Weight of the accelerometer sensor (including coiled cord): about 85 grams (0.2 pounds).
- Weight with batteries, sensor, casing, without documents: about 660 grams (1.5 pounds).
- Temperature range: use from +5°C to +30°C (40° F to 85° F) ; storage from -10°C to +50°C (15° F to 120° F).
- Duration of the measurement in the 20 SECOND MEASURE mode: 20 seconds.
- Frequency of the display in the CONTINUOUS MEASURE mode: one second intervals.
- Energy consumption: approx. 0.01 W (2.5 mA at 4.5 V).
- Power supply: 4.5 V DC, with three 1.5 V standard batteries type AA or LR6 - capacity of approximately 1.500 mA-hours, good for about 600 hours of operation.
- Lifetime of a set of batteries in the 20 SECOND MEASURE mode: about 100 000 20&endash;second measurements, that is, 40 measurements a day during 5 years.
- Duration of a set of batteries in the CONTINUOUS MEASURE mode: about 5 years if used continuously for 10 minutes each day.
- Automatic stop-battery saver: after 1 minute of total immobility of the sensor.
- Band width: 3 to 20 Hz. With this band width, one can measure all types of human physiological tremors, psychological stress, senile tremor and pathological tremors (including Parkinsonian tremor and essential tremor).
- Definition of the measuring scale: linear accelerometric scale graduated in TNR COMBY units ranging from 0 to 999 ; 0 corresponds to total immobility of the sensor and 999 is the maximum range. One unit of TNR = 6,66 x 10-4m/s2 = 0,167 micrometer of amplitude at 10 Hz. A sinusoidal oscillation of amplitude 1 µm at 10 Hz corresponds to 6 units of TNR COMBY.
- Results: digitalized results are shown on a 3-digit liquid crystal digital display (LCD).
- Definition of the tremor scale: the REFERENCE SCALE is a linear accelerometric scale. A sinusoidal oscillation at 10 Hz of frequency and 1 µm in amplitude corresponds to 6 TNR units: 1 TNR unit = 6,66 x 10-4m/s2 = 0,167 micrometer of amplitude at 10 Hz. The precision of the sensor is about 1 TNR unit, about one tenth of a thousandth of millimeter (0.1 micrometer) in amplitude.
- CONTINUOUS MEASURE mode:
By pressing the CONTINUOUS MEASURE button, the tremor level of the subject is continuously displayed. While observing the variations of the tremor, the patient can perform stress management and educational exercizes (relaxation, meditation, self-hypnosis, concentration, respiration ) to gain control of his body and emotions, learning how to manage his stress. The subject thus progressively learns, through biofeedback training, a better control of his nervous system. The TNR measurements displayed give a direct image of the subject's nervous activity. It is more direct and more precise for biofeedback applications than temperature or GSR (galvanic skin resistance). The STRESSOMETER is therefore used by a number of biofeedback practitioners.
Such educational sessions can last typically 5 to 10 minutes. Used in this mode, the STRESSOMETER helps reduce nervous disorders and increases one's neuromuscular coordination and stress-control (applications for body management, students preparing exams, sports competition, etc.).
In the CONTINUOUS MEASURE mode, the STRESSOMETER is more than a measuring instrument: it is an educational, interactive biofeedback system which contributes in reducing stress, gaining better control of one's emotions, and improving one's neuromuscular precision, control and performance.
- 20 SECOND MEASURE mode:
By pressing the 20 SECOND MEASURE button, in this mode, the STRESSOMETER measures the Tremor of the Nervous system at Rest (TNR) of the subject in 20 seconds. The signal is treated electronically to eliminate the irrelevant vibrations. The result then appears on the liquid cristal digital display. In this 20 SECOND MEASURE mode, comparisons can be made between individuals, and the evolution over time of an individual's TNR can be followed, in respect to changes in his lifestyle, activities, training exercizes, nutritional balance (diet influences tremor) and other factors affecting one's stress and nervous condition. If the TNR is repeatedly located in the « High » or « Very high » zone, it is strongly advised to consult a physician.
- The electronic circuit of the STRESSOMETER COMBY type ADTM 60 measures the human nervous tremor which is influenced by stress and emotions: it is a portable version that can be carried and used in a wide variety of circumstances by: the public, for corporate stress management programs, for training, in sports competition, and for all those who want to gain better knowledge and better control of their nervous system.
- User friendly: as a scientific instrument, the STRESSOMETER offers high precision measurements, but yet it is user-friendly and simple to use, thanks to highly integrated technology. The electronic microchip does all the data treatment and calculations automatically. It eliminates parasite signals. Just respect the standard measuring position (SMP), press the ON button and choose your measurement mode (CONTINUOUS or 20 SECOND).
- Main case: modern and elegant design of the sensor and casing. The Stressometer is delivered to the customer as a complete ready to use measuring instrument and stress-reducing method including: the Stressometer, the high precision sensor, the casing, the batteries, the user's manual and exercizes to reduce one's stress.
- High precision sensor: to be held in the dominant hand: right hand for right-handed, left hand for left-handed.
