HVD3605 / HVD3605A Voltage Derating and Burn Limit
The Maximum Input Voltage curve (solid line) shows the maximum voltage that can be
applied to the probe inputs without risking damage to the probe.
The lower Burn Limit curve (dashed line) shows the maximum voltage that can be applied
to the probe inputs while the operator is handling the inputs. Handling the inputs while
connected to active signals above this burn limit could result in injury to the operator.
WARNING. To avoid risk of electric shock or fire, comply with the burn limit when
measuring high-frequency signals with hand-held accessories. Do not exceed the
voltage or category rating of the probe or accessories (whichever is less). Keep your
fingers behind the finger guard of the probe. Keep the probe body and output cable
away from the circuits being measured. Use only the specified accessories.
