Important safet
y information
Beware of high voltages. Understand the voltage ratings for the probe you are using and do not exceed those ratings.
Two ratings are
important to know and understand:
The maximum me
asurement voltage from the probe tip to the probe reference lead
The maximum flo
ating voltage from the probe reference lead to earth ground
These two volt
age ratings depend on the probe and your application. Refer to the Specifications manual for more information.
WARNING. To prevent electrical shock, do not exceed the maximum measurement or maximum floating voltage for the
oscilloscope input BNC connector, probe tip, or probe reference lead.
Connect and disconn
ect properly.
Connect the probe output to the measurement product before connecting the
probe to the circuit under test. Connect the probe reference lead to the circuit under test before connecting the probe input.
Disconnect the probe input and the probe reference lead from the circuit under test before disconnecting the probe from
the measurement pr
oduct.
Connect and disconnect properly. De-energize the circuit under test before connecting or disconnecting the current
probe.
Connect the probe reference lead to earth ground only.
Do not connect a current probe to any wire that carries voltages above the current probe voltage rating.
Inspect the probe and accessories. Before each use, inspect probe and accessories for damage (cuts, tears, or
defects in the probe body, accessories, or cable jacket). Do not use if damaged.
