3.2 Serial Number:
Load plate, loading device and testing computer form a single unit and
have been attuned to one another during calibration of the device. These
three components may only be used in conjunction with each other and
may not be interchanged with the components of other devices.
Accordingly, the single components are identified with particular serial
numbers. These serial numbers are identical and located on metal tags,
which are attached to each component. Each serial number consists of
a four-digit number.
The serial number is located:
On the load plate, directly between the handles.
Inside the testing computer, on the partition panel in the storage box.
On the drop weight of the loading device. Additionally, drop height as
well as month and year of last calibration are noted here.
