Disable the product if it is damaged. Do not use the product if it is damaged or operates incorrectly
. If in doubt about safety of the product,
turn it off and disconnect the power cord. Clearly mark the product to prevent its further operation.
Before use, inspect voltage probes, test leads, and accessories for mechanical damage and replace when damaged. Do not use probes or
test leads if they are damaged, if there is exposed metal, or if a wear indicator shows.
Examine the exterior of the product before you use it. Look for cracks or missing pieces.
Use only specified replacement parts.
Do not operate in wet/damp conditions
Be aware that condensation may occur if a unit is moved from a cold to a warm environment.
Do not operate in an explosive atmosphere
Keep product surfaces clean and dry
Remove the input signals before you clean the product.
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. It is important to know and understand he
maximum measurement voltage from the probe tip to the probe reference lead.
The voltage rating depends on the probe and your application. Refer to the Specifications section of the manual for more information.
WARNING: T
o 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.
WARNING: T
o prevent damage to the alligator clip insulation, do not use in high A/m magnetic fields at high frequencies, which
can cause induction heating of the jaws.
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.
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.
