RA(WU150) REV. 02- 10/01/2017 2
By choosing the WUNDER model RA professional electronic scale, you have purchased a high precision
instrument.
Since over 40 years WUNDER has placed its experience at the service of health. This instrument is
compliant with national standards in hospitals and clinics with medical class I with measurement function
and Is calibrated in conformity with accuracy class III.
The instrument is characterised by the possibility of fixing the electronic terminal to the weighing platform by
means of a column or else installing the terminal autonomously.
The instrument is equipped with a dual LCD electronic terminal with triple reading to simultaneously view
Weight, Height. and BMI

environment due to fixed RF transmitters, it should consider the electromagnetic survey of the site. If the
field strength measured at the place where you use the instrument exceeds the applicable level of
compliance of the above, it should be placed under observation normal operation of the tooth divice. If you
notice abnormal performance, it may take additional measures as a different orientation or position of
instrument.

For transmitters with maximum rated power output not reported above, the recommended separation
distance d in meters (m) can be calculated using the equation applicable to the frequency of the transmitter,
where P and the maximum rated power output of the transmitter in Watt (W) according to the manufacturer
