FCC information for the USA

This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more
of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to

which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

Important

This equipment was tested for FCC compliance under conditions that include
the use of shielded test leads between it and the peripherals. It is important
that you use shielded cables and connectors to reduce the possibility of
causing Radio and Television interference.

Shielded probes, suitable for the PCS500 oscilloscope can be obtained
from the authorized Velleman dealer.

If the user modifies the PCS500 oscilloscope or its connections in any way,
and these modifications are not approved by Velleman, the FCC may withdraw
the user’s right to operate the equipment.

The following booklet prepared by the Federal Communications Commission
may be of help: “How to identify and Resolve Radio-TV Interference problems”.
This booklet is available from the US Government Printing Office, Washington,
DC20402 Stock No. 044-000-00345-4.

GENERAL

The PCS500 / PCS100 / K8031 are digital storage oscilloscopes, using a
computer and its monitor to display waveforms. All standard oscilloscope
functions are available in the Windows program supplied. Its operation is just
like a normal oscilloscope wit h the difference that most operations can be
done using the mouse. The markers for indicating voltage and frequency also
provide considerable ease of use and can be operated without difficulty using
the mouse. Apart from being used as an oscilloscope, the unit can also be
used as a spectrum analyzer and as a transient signal recorder, for recording
voltage variations or for comparing two voltages over a longer period (over
more than a year!). Connection is through the computer's parallel port; the
scopes are completely optically isolated from the computer port. Any waveform
displayed on the screen can be stored for later use in documents or for
comparison of waveforms. Together with the PCG10 function generator, a
powerful Bode plotter can be made. In the PCS500 the oscilloscope and
transient recorder have two completely separated channels.

SAFETY and WARNINGS

Symbols displayed on the unit

!

Important safety information, see user manual.

The PC scopes are optically isolated from the PC, but even then it

is advisable to measure only safe devices.

⇒ Measurements should be avoided in case of polluted or very humid air.

One should also refrain from measuring conductors or installations that
use voltages that exceed 600Vrms above ground level. CAT II indicates
conformity for measurements of domestic installations.

⇒ The maximum input voltage for the connections of the unit stands at 100Vp

(AC+DC)

⇒ Do NOT open the enclosure while performing measurements.
⇒ Remove all test leads before opening the enclosure in order to avoid

electrical shock.

⇒ Use a measuring probe with an insulated connector ( e.g. type

PROBE60S) when measuring voltages exceeding 30V.

Before making measurements and for safety reasons, it is important to know
some information about the measured unit.
Safe devices are:

• Battery operated equipment

• Equipment supplied via a transformer or adapter.

Unsafe devices are:

• Equipment directly connected to mains (e.g. old TV sets)

• Equipment that contains components that are directly connected to mains

(dimmers…).
It is advisable, when measuring on above equipment, to use a isolation
transformer.
Always be careful when measuring directly to the mains; please remember

that the ground of both channels is interconnected!

FIMPORTANT: Prior to measuring high voltages, set the probe to the X10

position.
