HVFO103 High-Voltage Fiber Optically Isolated Probe
Except for gain accuracy adjustment, do not remove the probe's casing. Touching exposed
connections may result in electric shock.
Use only indoors and within the operational environment listed. Do not use in wet or explosive
atmospheres.
Keep product surfaces clean and dry.
Handle with care. Probe tips are sharp and may cause injury if not handled properly.
Do not operate with suspected failures. Before each use, inspect the probe and accessories for
damage such as tears or other defects in the body, cable jacket, etc. If any part is damaged,
cease operation immediately and sequester the probe from inadvertent use.
High Voltage Precautions
To avoid injury or death due to electric shock or burn:
Do not handle probe tips, leads or any part of the amplifier/modulating transmitter at any time if
DC bus voltages are >60 V. The probe is not rated for hand-held use above 60 V. If there is any
question as to whether >60 V voltages are present in the circuit, use caution and DO NOT touch
these components.
Always ensure that, when not hand-held, the amplifier/modulating transmitter and attached tip
are positioned to maintain adequate spacing between these two components and earth ground.
Some of the probe components float at the common-mode voltage and some do not. The
spacing requirements depend on the common-mode voltage present in the test setup.
