Temperature and Humidity Requirements
The best possible performance of the measuring machine is ensured during operation if the environmental
requirements specified in the table below and, more generally, in the relevant Hexagon procedure are strictly
respected.
See the Technical Data bulletin for the model of the GLOBAL S measuring machine in use to find out the
measuring performance that may be obtained when specific conditions for maximum measuring precision
and the experimental conditions are satisfied.

Table 4 Conditions for Maximum Precision
Electrical Power Supply
The measuring machine is powered by the control system. For detailed information on the electrical
characteristics, see the documentation provided with the control system in use.
Machines and devices manufactured by Hexagon work correctly within the limits laid down by the EN60204-
1 and EN 61000-6-2 standards.
Z-rail Counterbalancing System
Pneumatic and adjustable.
Maximum weight applicable to the Z-rail
Maximum weight that can be added to or removed from
the counterbalanced Z-rail without having to rebalance
the weight of the Z-rail itself and without altering the
machine’s measuring precision
