Maximum input ranges
Observe all terminal ratings and warnings marked on the product.
The table below indicates the full scale measurement range and overvoltage protection
range for each oscilloscope model. The full scale measurement ranges are the
maximum voltages that can be accurately measured by each instrument. The
overvoltage protection ranges are the maximum voltages that can be applied without
damaging the oscilloscope.
WARNING
To prevent electric shock, do not attempt to measure voltages outside the
specified full scale measurement range below.

WARNING
Signals exceeding the voltage limits in the table below are defined as
"hazardous live" by EN 61010. To prevent electric shock, take all necessary
safety precautions when working on equipment where hazardous live voltages
may be present.
Signal voltage limits of EN 61010
±70 V DC
33 V AC RMS
±46.7 V pk max.
WARNING
PicoScope 3000D Series oscilloscopes are not designed to measure
hazardous live signals as defined by EN 61010. To prevent electric shock, do
not attempt to measure voltages outside of the limits shown in the table
above or the specified full scale measurement range, whichever is lower.
WARNING
To prevent injury or death, the oscilloscope must not be directly connected
to the mains (line power). To measure mains voltages, use a differential
isolating probe specifically rated for mains use, such as the TA041 listed at
CAUTION
Exceeding the overload protection range on any connector can cause
permanent damage to the oscilloscope and other connected equipment.
