Maximum Input Ranges - PICO PicoScope 9000 Series Quick Start Manual

PicoScope 9000 Series Quick Start Guide
WARNING
To prevent injury or death use the product only as instructed and use only accessories
supplied or recommended. Protection provided by the product may be impaired if
used in a manner not specified by the manufacturer.

2.2 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 range is the maximum voltage that can be
accurately measured by the instrument. The overvoltage protection range is the maximum voltage
that can be applied without damaging the instrument.
WARNING
To prevent electric shock, do not attempt to measure voltages outside the specified
full-scale measurement range below.
Model
All PicoScope 9000
Series oscilloscopes
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.
± 70 V DC
PicoScope 9000 Series PC 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.
CAUTION
To prevent permanent damage, do not directly connect the high-voltage differential
step generator of the PicoScope 9311 to channel inputs or other equipment. Do not
remove the 20 dB pads fitted to the generator outputs, as they ensure the signal is
reduced to safe levels. Do not replace the pads with smaller values unless safety is
ensured by other test circuit losses and peak ratings.
CAUTION
Exceeding the overload protection range on any connector can cause permanent
damage to the oscilloscope and other connected equipment.
