Getting Started
Probe Safety
Check and observe probe ratings before using probes.
A guard around the probe body provides a fi nger barrier for protection from
electric shock.
Finger guard
WARNING.
To avoid electric shock when using the probe, keep fi ngers behind
the guard on the probe body.
To avoid electric shock while using the probe, do not touch metallic portions of
the probe head while it is connected to a voltage source.
Connect the probe to the oscilloscope, and connect the ground terminal to ground
before you take any measurements.
Any probe or cable used to apply more than 30 VAC
RMS
(42 V peak) to the
oscilloscope BNC input connector must be third-party certi fi ed for the voltage
to be applied, including rating the probe reference lead or cable shield to fl oat to
600 V
RMS
CAT II.
This manual contains important information on isolated channels, fl oating
measurements, and high voltages. (See page 3, Taking Floating Measurements .)
WARNING.
Do not fl oat the TPP0101 or TPP0201 probe reference lead to >
30 V
RMS
. Use the P5120 probe ( fl oatable to 600 V
RMS
CAT II or 300 V
RMS
CAT III)
or similarly rated, passive, high voltage probe (not the ground referenced P5100
probe), or an appropriately rated, high voltage, differential probe when
fl oating
the reference lead above 30 V
RMS
, subject to the ratings of such high voltage probe.
To avoid electric shock when using probes with exposed metal parts, do not
connect the reference lead to voltages above 30 V
RMS
.
