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.

Extras

  • Hints

    • Use a 9V DC non-regulated powersupply (PS905), or a 12 V DC regulated power supply. Do NOT use a non-regulated 12 V powersupply.
    • The use of alkaline batteries is NOT recommended.
    • If the scope shows 'startup' troubles ( the on-led lights, but the display remains blank ) when run on batteries, try replacing T6, BC547B or BC547C with a BC517 and replace ZD1, 5V6 with a 6V2 type.
