AddiƟon to the instrucƟon of medical scales
1. The manufacturer is not liable for the consequences of using the scale, in circumstances not
provided for operaon, including the power supply parameters other than those listed below:
a. 60mA 12V DC min
b. Polarity
c. Female plug 2.1 mmx9mm
2. When you turn on the scale and the weight, moving parts (pan of the scale and its structural
components) can not touch any part of the fixed - not related to the pan (wall coverings, other
equipment or apparatus, etc.) This may prevent the inclusion of the scale or the wrong indicaon.
3. When you weighing on the baby scale, the child should be placed to prevent it from slipping from
the pan. A child can not remain on the pan without adult responsible for his safety.
4. When you weighing on the personal medical scale the paent should be in a safe and stable stand
with both feet on the pan.
5. In the scale of the weighng chair scale two feet of the paent should be based on the turnover
brackets.
6. The manufacturer shall not be liable for the consequences of non-checking and verificaon in
requiring period of me for parcular scales referred to the convenient regulaons:
a. Verificaon by the Main Measuring Office should be held before the expiry of three years
from 1 December of the year in which the inial assessment of compliance. Last two digits
of the year in which the inial assessment of compliance are placed on a scker on
hologram (along with the number of units cerfied - the office issuing the check measure
weight) glued next to the plate of the scale.
Legal basis Art 8k paragraph. 3 of the Act of 11 May 2001 Law on Measures (Dz. U of 2004
No. 243, poz.2441, 2005, No. 163, item. 1632, No. 180, 1494, from 2006 r.Nr 170 , pos.
1217, No. 249, item. 1834, 2007, No. 176, item. 1238, in 2008, No. 227, poz.1505, of 2009,
No. 18, item. 97).
b. The next test (re-legalizaon) should be carried out within 25 months from the first day of
the last re-verificaon. Next to the plate are glued (the re-verificaon) 2 with the hologram
scker: monthly (Roman) and annual (two Arabic numerals).
Legal basis: § 27 and 28 and Annex 6 of the Minister of Economy dated 7 January 2008. on
legal metrological control of measuring instruments (Journal of Laws of 2008, No. 5, item
29)..
7. Declaraon and informaon on electromagnec emissions (EMC). Scales are designed to work in
any premises, including dwellings. Scales do not have any radio transmiers, the minimum
electromagnec emissions in the range of 9 kHz to 3 GHz is a result of the scale measurement
system and praccally eliminates any effect on the devices in the immediate vicinity. In accordance
with BS EN 60601-1-2.
8. Declaraon and informaon according to the resistance of the scale on factors - noise. All of the
following distorons do not increase the scale of the errors above the limit values for the parcular
type. However there is not desirable, long-term work under boundary confounders.
a. Changes in the supply voltage:
The lower limit Vmin = V-15%;
The upper limit Vmax = V +10%;
b. Short-term decreases in voltage electricity
Decrease in amplitude = 100% for a half period;
Decrease in amplitude = 50% for 2 half periods;
c. Electrical glitches in electricity with a value of 1 kV.
d. Electrostac Discharge at least 10x at intervals of 10s:
Direct 6kV;
Indirect (by air), 8kV;
e. Electromagnec radiaon: Frequency range 26 MHz to 1 GHz;
Magnec field of 3V / m;
Modulaon 80% AM, 1 kHz sine wave.
In accordance with BS EN 45501
