【正文】 ronic equipment.When it must be assumed that safe operation is no longer possible,the puter,charge amplifier,etc. must be taken out of operation and secured against unintentional use.Whenever opening covers or removing where this can be done by hand,use caution where parts under hazardous voltage are exposed. WarningAny breakage of the ground conductor inside or outside the insrtumerts,or loosening of the ground conductor connection may render the instrument dangerous.The power plug must be inserted in to a socket with a ground connector. The protection must not be nullified by an extension line lacking a protective ground connector.When changing the signal conditioner fuses,only the stangard type with the specified or shortcircuiting the fuse holder is expressly forbidden. How To Use This ManualWhether you are a novice at puters or a long time programming expert,you will bee familiar with the operation of DynoWare.
