Ground the measuring instrument
The protective grounding terminal of the oscilloscope must be
connected to ground.
Check the grounding
Before connecting the probe input terminal to the device under
measurement, ensure that the measuring instrument is grounded
properly and that the probe's BNC connector is connected to the
oscilloscope input.
Observe the maximum input voltage
Do not apply voltage exceeding ±100 V instantaneously or ±35 V
(DC + ACpeak) continuously between an input lead and ground or
between two input leads.
Be careful of electric shock
Never use the probe with wet hands or when the probe itself is wet.
Doing so may cause electric shock. Be careful of electric shock
when you connect the probe to the device under measurement.
Avoid exposed circuitry
To prevent electric shock, remove metal and jewelry such
as watches and rings. Do not touch exposed connections or
components when power is present on the device.
Precautions when connecting and disconnecting the probe
Do not disconnect the probe from the oscilloscope while the probe
is connected to the device under measurement. Doing so may
cause electric shock.
Do not operate in wet or damp conditions
To prevent electric shock, do not operate the probe in wet or damp
conditions.
Do not operate in explosive atmosphere
To prevent injury or fire hazard, do not operate the probe in an
atmosphere of flammable or explosive gases or vapors.
Do not operate with suspected failures
Stop using the probe if you suspect that the probe is damaged.
Consult your nearest YOKOGAWA dealer.
