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 verication

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 verication

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 rst putting

into use. After this, the national regulations for

devices subject to legal verication apply within

the EU.
