Probe and Test Leads
Before connecting probes or test leads, connect the power cord from the power connector to a properly grounded
power outlet.
Keep fingers behind the protective barrier, protective finger guard, or tactile indicator 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 floating voltage from the probe reference lead to earth
ground.
These two voltage ratings depend on the probe and your
application. Refer to the Specifications section of the manual for more
information.
Warning: To prevent electrical shock, do not exceed the maximum
measurement or maximum floating voltage of the oscilloscope input.
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 or
frequencies 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.
Grounding reference for
Oscilloscope
Do not float the reference lead of this probe when used with an oscilloscope
with ground as reference. The reference lead must connect to ground
potential (0V).
Use floating measurement
Do not float the reference lead of this probe above to the floating voltage.
