Warranty and Repair

HAMEG instruments are subjected to a strict qua-
lity control. Prior to leaving the factory, each in-
strument is burnt-in for 10 hours. By intermittent
operation during this period almost all defects are
detected. Following the burn-in, each instrument
is tested for function and quality, the specifications
are checked in all operating modes; the test gear
is calibrated to national standards.
if the instrument shows visible damage,
if the instrument has loose parts.
if the instrument does not function,
after long storage under unfavourable cir-
cumstances (e.g. outdoors or in moist envi-
ronments),
after excessive transportation stress (e.g. in
poor packaging).
