Probe Safety

Check and observe probe ratings before using probes.
A guard around the P2220 voltage probe body provides a finger
barrier for protection from electric shock.
WARNING. To avoid electric shock when using the probe, keep
fingers 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 before you connect the probe
to your circuit to take any measurements.
Any non-attenuating probe that applies more than 150 VAC to the
oscilloscope BNC input connector must be third party certified with
the probe reference lead rated to float to 300 V CAT II.
For information on isolated channels and floating measurements, see
page 1- - 4. For information on high voltages, see page 1- - 5.
WARNING. Do not float the P2220 probe reference lead to > 30
V . Use the P5120 (floatable to 600 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
voltage probe.
