General Safety Summary
Review the following safety precautions to avoid injury and prevent
damage to this product or any products connected to it.
To avoid potential hazards, use this product only as specified.
Only qualified personnel should perform service procedures.
To Avoid Fire or Personal Injury
Use Pro er Power Cord. Use only the power cord specified for this
product and certified for the country of use.
Connect and Disconnect Pro erly. Do not connect or disconnect probes
or test leads while they are connected to a voltage source.
Connect and Disconnect Pro erly. Connect the probe output to the
measurement instrument before connecting the probe to the circuit
under test. Disconnect the probe input and the probe reference lead
from the circuit under test before disconnecting the probe from the
measurement instrument.
Observe All Terminal Ratings. To avoid fire 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.
Use Pro er Probe. To avoid shock hazard, use a properly rated probe
for your measurement.

Floating. Do not float the P2220 probe reference lead to > 30 V RMS.
Use the P5120 (floatable to 600 V RMS CAT II or 300 V RMS CAT
III) or similarly rated, passive, high voltage probe or an appropriately
rated, high voltage differential probe when floating the reference
lead above 30 V RMS, subject to the ratings of such high voltage
probe.
Powering Off. The power cord provides Mains disconnect.
Re lace Batteries Pro erly. Replace batteries only with the proper type
and rating specified.
Recharge Batteries Pro erly. Recharge batteries for the recommended
charge cycle only.
Use Pro er AC Ada ter. Use only the AC adapter specified for this
product.
Do Not O erate Without Covers. Do not operate this product with
covers or panels removed.
Avoid Ex osed Circuitry. Do not touch exposed connections and
components when power is present.
Do Not O erate With Sus ected Failures. If you suspect there is damage
to this product, have it inspected by qualified service personnel.
Environment. Pollution Degree 2 (As defined in IEC61010--1:2001).
Do not operate in an environment where conductive pollutants may
be present. See Appendix A of the TPS2000 Oscilloscope User

Provide Pro er Ventilation. Refer to the manual’s installation
instructions for details on installing the product so it has proper
ventilation.
Avoid Electric Overload. To avoid injury or fire hazard, do not apply
potential to any input, including the reference inputs, that varies
from ground by more than the maximum rating for that input.
Avoid Ex osed Circuitry. Do not touch exposed connections and
components when power is present.
Avoid Electric Shock. To avoid injury or loss of life, do not connect or
disconnect probes or test leads while they are connected to a voltage
source.
Kee Probe Surface Clean and Dry. To avoid electric shock and
erroneous readings, keep probe surface clean and dry.
Attached the Reference Leads Correctly. If you are using multiple
oscilloscope channels, you must attach the probe reference lead for
each channel directly to the circuit common reference that you are
measuring. These connections are required because the oscilloscope
channels are electrically isolated. They do not share a common
chassis connection. Use the shortest possible reference lead with
each probe to maintain good signal fidelity.
If Question Marks are Dis layed. If a measurement display is followed
by a question mark, or a question mark is displayed instead of a
value, you have encountered an overrange condition or other error,
the reading may be invalid, and hazardous voltages may be present.
Readjust the vertical scale or position or press the front-panel
AUTOSET button.
