Injury
Use Proper Power Cord. Use only the power cord specied for this product and
certied for the country of use.
Use Proper Voltage Setting. Before applying power, ensure that the line selector
is in the proper position for the source being used.
Connect and Disconnect Properly. Do not connect or disconnect probes or test
leads while they are connected to a voltage source.
Connect and Disconnect Properly. De-energize the circuit under test before
connecting or disconnecting the current probe.
Connect and Disconnect Properly. Connect the probe output to the measurement
instrument 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 instrument.
Ground the Product. This product is grounded through the grounding conductor
of the power cord. To avoid electric shock, the grounding conductor must be
connected to earth ground. Before making connections to the input or output
terminals of the product, ensure that the p roduct is properly grounded.
Ground the Product. This product is indirectly grounded through the grounding
conductor of the mainframe power cord. To avoid electric shock, the grounding
conductor must be connected to earth ground. Before making connections to
the input or output terminals of the product, ensure that the product is properly
grounded.
Observe All Terminal Ratings. To avoid re or shock hazard, observe all ratings
and markings on the product. Consult the product manual for further ratings
information before making connections to the product.
The inputs are not rated for connection to mains or Category II, III, or IV circuits.
Connect the probe reference lead to earth ground only.
Do not apply a potential to any terminal, including the common terminal, that
exceeds the maximum rating of that terminal.
