Overvoltage Protection - pico Technology PicoConnect 442 Guia Del Usuario

2.3 Maximum input ranges
Observe all terminal ratings and warnings marked on the product.
WARNING
To prevent electric shock, do not use the probe with voltages above the
following limits:
+ve to chassis 1000 V DC + AC pk
–ve to chassis 1000 V DC + AC pk
+ve to –ve 1000 V DC + AC pk
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
precautions when working on equipment where hazardous live voltages may
be present.
±70 V DC
WARNING
Operation outside of the above measurement or protection ratings is likely
to cause permanent damage to the product, connected equipment and the
protection that it provides. DO NOT continue to use a probe that may have
been compromised.
WARNING
To avoid injury or death, observe all safety precautions appropriate to the
circuit under test.
2.4 Environment
