Velleman Kits & Projects

This handheld scope features options never seen in its category. It is packed with handy features which enables you to perform on-the-spot measurements quick, easy and accurate. Its high-contrast, wide viewing angle LCD screen enables operation under normal daylight conditions. All functions are accessible by means of a tactile keyboard with a pleasant touch feeling. The current operating mode is displayed on-screen. If desired, auto-setup mode takes care of all scope settings for instant visualisation of waveforms. The marker function enables you to make accurate measurements of voltage, time and frequency. Acting as a DVM, it displays True RMS, dB, peak-to-peak and DC volts. With its built-in variable gain sine generator, it allows easy service of audio equipment, etc.… Probe transient response can be adjusted using the calibration output. Finally, a RS232 port enables screen data to be sent to a PC for use in different applications. A charge circuit with indicator LED for rechargeable batteries is provided.

Charges NiCd or NiMH batteries, ideal for use in cars or boat. Transforms a standard mains adapter in to a charger (adapter socket included). Charge cellular phone, toys, portable CD or Mini Disc players, video batteries etc. Selectable charging current. LED charge indication.

To enable a computer to communicate with the outside world, it is usually fitted with a keyboard, a display and perhaps a mouse. If however it is to be used in certain control applications, or certain control functions are to be carried out, then an interface is needed. The interface card here excels in its simplicity of use and installation. The card is connected in a very simple way to the printer port (there is no need to open up the computer). Likewise there is no need to install an extra printer port, even if a printer is to be used. This can be connected to the card in the usual manner. Connection to the computer is optically isolated, so that damage to the computer from the card is not possible. The card is controlled in a simple way using Turbo Pascal, QBasic, Visual Basic, Delphi, C++ (to use with MS-DOS, Win3.11, Win95, 98, ME, NT, XP, 2000). These procedures are pre-programmed and are provided along with a number of test and example programs on the diskette supplied. The card itself has 16 optically isolated digital connections, which can be freely chosen as either inputs or outputs (eg. 6 inputs and 10 outputs) according to how they are set up by the user. Furthermore, the card has 9 analogue outputs, of which one is high precision, and 4 analogue inputs. If this capacity is not sufficient for a particular application then up to 4 cards can be connected together (1 master and 3 slaves), such that an enormous potential exists. The card can be used with many of our other kits such as : K6714 16 channel relay card, K8023 10-channel 2-wire remote control.
