HIGH-VOLTAGE PRECAUTIONS

CAUTION:

This instrument provides output voltages as high as 250 Volts under

normal operating conditions, and generates > 250V internally, so extreme caution must
be employed when using this instrument. The instrument should only be used by
individuals who are thoroughly skilled in high voltage laboratory techniques. The
following precautions should always be observed:

1. Keep exposed high-voltage wiring to an absolute minimum.

2. Wherever possible, use shielded connectors and cabling.

3. Connect and disconnect loads and cables only when the instrument is turned off.

4. Keep in mind that all cables, connectors, oscilloscope probes, and loads must have

an appropriate voltage rating.

Do not attempt any repairs on the instrument, beyond the fuse replacement procedures
described in this manual. Contact Avtech technical support (see page 2 for contact
information) if the instrument requires servicing.
