ZENNER MULTIDATA WR3 - Manual (Page 2)

General information
With multidata you have acquired one of the
most up-to-date, modern heat calculators cur-
rently available on the market.
Expressive symbols in the display and easy
menu navigation make readout simple. It can be
operated with one single button. The setting of
the data loggers (depending on the type of de-
vice) is being done via the software GMM.
The calculator is equipped with a long-life battery
made for operation during the initial verification
validity period (5 years) including a reserve of at
least another year. With a second battery you will
reach 11 years. Initial verification
multidata is produced and tested in compliance
with the new European measuring instruments
directive (MID). According to this directive, de-
vices do no longer carry an initial verification
stamp, but rather the year of the device’s decla-
ration of conformity (recognizable on the front of
the device, for example: M09). The MID controls
the use of heat meters up to the moment they
are placed on the market resp. their first putting
into use. After this, the national regulations for
devices subject to legal verification apply within
the EU.
