Connecting to the Terminals
• Note the following maximum input voltage and maximum rated
voltage to earth.
600 V AC/DC (CAT III, II), 300 V AC/DC (CAT IV)
If their voltages are exceeded, this device will be damaged and
personal injury will result. Therefore, do not perform measure-
ment in this case.
The maximum allowable input voltage is the smaller of that of the
instrument or of the measurement cables.
• The relationship between the maximum allowable input voltage
and the maximum rated voltage to earth of the combined Mem-
ory HiCorder and measurement cables is as follows.
To avoid electric shock or damage to the instruments, do not
apply input voltage above the lowest maximum.
The maximum rated voltage to earth in the table applies when
measuring through input attenuators.
