Safe Operating the Probe PHV1000
The PHV1000 is rated for 1000V AC rms or DC 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, derating 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 PHV1000 is designed for ground-referenced measurements only.
About PHV Probe Series
The PHV1000 is the PMK general purpose high voltage probe with a 100:1 attenuation. Its fast rise time and
accurate frequency response make it suitable for a variety of measurement applications. The very sharp probe
tip is spring loaded and minimizes the pressure to the dut (device under test). It also prevents the probe from
slipping on the board surface. Especially when probing at an angle. The probe tips are changeable. Replacement
tips are provided within the accessory pack. Refer to the maintenance section to learn how to change the probe
tip.
