PCS500 / PCS100 / K8031
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 with 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.
ÞMeasurements 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.
ÞThe maximum input voltage for the connections of the unit stands at 100Vp (AC+DC)
ÞDo NOT open the enclosure while performing measurements.
ÞRemove all test leads before opening the enclosure in order to avoid electrical shock.
ÞUse 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.
