Probes 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 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.
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.
