HANDHELD LCD OSCILLOSCOPE Velleman K7105 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.
