  • Page 7: Safety And Warnings

    _________________________________________________________________________________________________________________________________________________________ SAFETY AND WARNINGS • The PersonalScope is ideally suited for measurements of category II installations with pollution degree 1 and using a maximum of 600V, in accordance with the IEC1010-1 norm. The enclosure is UL 94V0 listed • Consequently, all 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.

  • Page 8: Power Supply

    _________________________________________________________________________________________________________________________________________________________ POWER SUPPLY The HPS40 (HPS10) PersonalScope can be powered by means of an adapter, ordinary batteries or rechargeable ones. Rechargeable batteries are advised for intensive use. The higher the capacity of the rechargeable batteries, the longer the autonomy of the unit.

  • Page 10: Operation

    Use a standard terminal program or download software from our web site. ADJUSTING THE CONTRAST Short press: Backlight on/off. (Only for HPS40) Short press: Maximum contrast (Only for HPS10) Long press: Change the contrast. Keep pressing the ‘Contrast’-key to change the contrast. Release the button at the desired setting.

  • Page 11: Setup Menu

    A full grid divides the screen into reference lines.(Fig. 12) • Markers: Moveable markers in order to measure the signal (Fig. 13). • A cross inserts a coordinate system into the screen. (Just for HPS10) Notes: • The number of readout-digits depends on the selected display layout.

Auto power-off mode Select the desired off time: 15 minutes, 1 hour or infinite (no auto power off). Notes: • Before power-off, the scope holds the last screen. • The auto power-off timer is factory-set to 15min at first power-on or after a reset •...

    _________________________________________________________________________________________________________________________________________________________ READOUT SET-UP Press to call the meter 1 to 4 selection menu. Make use of the cursorkeys to set readout for up to 4 meters Setting up the measurement readouts: 1. Pressing the ‘meter’-key selects the first readout location. 2.

The signal's negative peak voltage (difference between zero and lowest value) is displayed. Peak to peak (Vpp). The signal's peak-to-peak voltage (difference between highest and lowest value) is displayed. True RMS readout (Vrms ac) The true RMS value of the AC wave is calculated and converted to voltage. dBV measurement (dBV ac).

    _________________________________________________________________________________________________________________________________________________________ • For all AC measurements: Make sure that at least one or two periods are displayed or select the auto-setup function. • You can choose “none” to hide readouts. • Depending on the selected screen layout one to four different meter readouts can be displayed. •...

  • Page 16: The Signal Markers

    A black bar (1) indicates the relative position of the signal in the sample window, see fig. 30. (Only for HPS40) Just for HPS10: A small dot in the left-hand corner of the screen will indicate the direction in which the signal has moved.

  • Page 17: Choice Of Input Coupling

    _________________________________________________________________________________________________________________________________________________________ Notes: • The Y-position cannot be shifted in ‘hold’-mode • A total of 256 samples are stored in memory, but the X-size of the screen is limited. By shifting the X-direction you can display all stored samples. • At dynamic display mode (set-up menu), the widest display layout is chosen by shifting the x-position. •...

  • Page 18: Changing The Input Sensitivity And Timebase

    Adjusting the time base will visualize more or fewer periods of a signal (t/div = time per division). The divisions can be visualized through the Display set-up key (see display setup). Set the time base between 1h and 50ns per division. (1h to 0,2µs for HPS10) Press the ‘t-V/div’-key to set the cursorkeys action into ‘timebase’ mode.

  • Page 19: Trigger Setup

    • Pressing the ‘t-V/div’’ key into hold mode toggles the screen between the two stored waveforms. • At higher timebase (1µs and faster, 2µs for HPS10) the scope uses Oversampling mode, only repetitive signals are correctly displayed. • Use the minimum time base (250ns) as a starting point when measuring a signal and select longer time bases until the signal is displayed properly.
  • Page 20 • At time base of 1s/div and slower, the input coupling is DC-only • Normal triggering is the only triggermode for timebases of 1µs/div or faster (2µs/div for HPS10) because of the oversampling method. • Keep pressing this key during “hold” mode stores the current screen into memory.

    _________________________________________________________________________________________________________________________________________________________ M e m o ry HOLDING THE SCREEN Press the ‘Memory’-key to freeze the waveform on-screen. It may be useful to "freeze" certain signals on your screen. This will allow the user to study the signal or perform measurements with the markers. (Fig 43) Fig 43 Remarks: •...

    _________________________________________________________________________________________________________________________________________________________ M e m o ry SENDING A SCREEN CAPTURE TO THE COMPUTER (Only for HPS40) It is possible to send a screen picture to your computer using the RS232 output. During „hold‘ mode press and keep pressing the memory key. A screen bit map (BMP) file will be send to the computer. A capture program can be downloaded from our site.

  • Page 23: Resetting The Personal Scope

    _________________________________________________________________________________________________________________________________________________________ RESETTING THE PERSONAL SCOPE (FIG. 47) Press the sunk (1) ‘Reset’ push button for at least 10 seconds to return to the manufacture-programmed setup. Note: • Use the reset function in case of unusual behaviour of the unit, like distorted screen or not functional keyboard (see also troubleshooting).
