Safety Instructions

To avoid personal injury and to prevent fire or
damage to this product or products connected
to it, review and comply with the following safety
precautions. Be aware that if you use this probe
assembly in a manner not specified the protection
this product provides may be impaired.
– Only qualified personnel should use this probe
assembly.
– Use only grounded instruments.
– Do not connect the probe ground lead to a
potential other than earth ground. Always
make sure the probe and the measurement
instrument are grounded properly.
– Connect and disconnect properly.
– Connect the probe output to the measurement
instrument and connect the ground lead to
earth ground before connecting the probe to
the circuit under test. Disconnect the probe
input and the probe ground lead from the circuit
under test before disconnecting the probe from
the measurement instrument.
Observe probe ratings.
– Do not apply any electrical potential to the probe
input which exceeds the maximum ratings of
the probe.
– Make sure to comply with the voltage versus
frequency derating curve on page 8.
Keep away from live circuits.
– Avoid open circuitry. Do not touch connections
or components when power is present.
– Do not operate with suspected failures.
– Refer to qualified service personnel.
Indoor use only.
– Do not operate in wet/damp environment. Keep
product surfaces dry and clean.
– Do not operate the product in an explosive
atmosphere.

Operating the Probe HZO20 safely
The HZO0 is rated for 1000 V
CAT II.
Note that the max. input voltage rating of the probe
decreases as the frequency of the applied signal
increases (see Derating section).
Refer to the relevant section of this instructions
manual for the maximum input voltages, dera-
ting information and definitions of relevant IEC
Measurement Categories (CAT).
Grounding the Probe
Connect the probe to the oscilloscope input and
connect the ground lead to earth ground before
performing any measurements. Note that all
accessible metal parts are connected to the BNC
instrument connector (GND), except for the probe
tip and the BNC centre-conductors.
The HZO0 is designed for ground-referenced
measurements only.
