Warranty

HAMEG warrants to its customers that the
products it manufactures and sells will be free
from defects in materials and workmanship for a
period of two years. This warranty shall not apply

describes briefly the faults observed. If at the
same time the name and telephone number
(dialing code and telephone or direct number or
department designation) is stated for possible
queries, this helps towards speeding up the
processing of warranty claims.

Maintenance

Various important properties of the module should
be checked carefully in certain intervals to ensure
that all signals and measurement results are
displayed with the accuracy on which the technical
data are based.
When removing the case detach mains/line cord
and any other connected cables from case of the
mainframe HM8001. Remove both screws on rear
