Important safety information
Keep fi ngers behind the fi nger guards on the probes.
Remove all probes, test leads and accessories that are not in use.
Use only correct Measurement Category (CAT), voltage, temperature, altitude, and amperage rated probes, test leads,
and adapters for any measurement.
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 measurement voltage from the probe tip to the probe reference lead.
The maximum fl oating voltage from the probe reference lead to earth ground
These two voltage ratings depend on the probe and your application. Refer to the Speci fi cations section of the manual
for more information.
WARNING. To prevent electrical shock, do not exceed the maximum measurement or maximum fl oating voltage for the
oscilloscope input BNC connector, probe tip, or probe reference lead.
Connect and disconnect 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 product.
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.
Ground-referenced oscilloscope use.
Do not fl oat the reference lead of this probe when using with ground-referenced
oscilloscopes. The reference lead must be connected to earth potential (0 V).
