_________________________________________________________________________________________________________________________________________________________ GENERAL FEATURES • • • • • • • • • • • • • • • • • • • High contrast LCD. With backlight (Only for HPS40). Full auto set up for volt/div and time/div. Recorder roll mode, up to 25h per screen. Trigger mode: run - normal - once - roll, slope -/+ Adjustable trigger level (Only for HPS40) Peak measurements: Max, min. and peak to peak.
_________________________________________________________________________________________________________________________________________________________ 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.
_________________________________________________________________________________________________________________________________________________________ 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. Attention: Use a non-regulated adapter of 9VDC that supplies a min. of 300mA.

_________________________________________________________________________________________________________________________________________________________ OPERATION G • • • NOTE: If functions are used together with cursor keys a short indication will pop up at the right bottom of the screen. Some keys have double function selected with a long --- or short — press. In most selections, the unit will return to the default t-V/div mode if no key is pressed during 10 sec, a selection will be cancelled.
_________________________________________________________________________________________________________________________________________________________ Fig 12 • • • • Fig 13 A dot grid divides the screen into reference points. (Fig. 11) 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.
_________________________________________________________________________________________________________________________________________________________ 2. Auto power-off mode Select the desired off time: 15 minutes, 1 hour or infinite (no auto power off). 2 G 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 • Selecting a slow time base (equal or slower than 1min/div) will disable the auto power off.
_________________________________________________________________________________________________________________________________________________________ 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. Press the cursorkeys to highlight the desired readout function for meter1 readout. (Fig. 17) 3.
_________________________________________________________________________________________________________________________________________________________ 3. Minimum voltage (Vmin.). The signal's negative peak voltage (difference between zero and lowest value) is displayed. 4. Peak to peak (Vpp). The signal's peak-to-peak voltage (difference between highest and lowest value) is displayed. 5. True RMS readout (Vrms ac) The true RMS value of the AC wave is calculated and converted to voltage. 6.
_________________________________________________________________________________________________________________________________________________________ • 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. • At 1s/div timebase or slower, the readouts are forced to the instant information. ‘Vs’ (Fig.
_________________________________________________________________________________________________________________________________________________________ Marker 1-2 THE SIGNAL MARKERS The user can perform measurements on a certain signal by using the four moveable markers. This can be useful when measuring the interval between two points or the amplitude of any given peak. The following indications will appear on the screen: 1 2 3 Fig 28 4 F 1. The time interval between two vertical markers. 2.
_________________________________________________________________________________________________________________________________________________________ G • • • • 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.
_________________________________________________________________________________________________________________________________________________________ Autorange on (Fig. 32): • • • • • • • Fig 32 Time/div and Volt/div settings are displayed inverted The time base and input sensitivity are automatically set for optimal viewing of the input signal. Auto-triggering is set for time base 2µs/div or slower, (HPS10 : 5µs/div) Normal triggering is set for time base faster then 2µs/div.
_________________________________________________________________________________________________________________________________________________________ G Note: • Changing the timebase or sensitivity switches the auto range mode immediately off. (Fig 36) • The timebase or sensitivity cannot be changed into hold mode. • Pressing the ‘t-V/div’’ key into hold mode toggles the screen between the two stored waveforms.
_________________________________________________________________________________________________________________________________________________________ G • • • • • • Notes: Pressing the Trigger key generates a manual triggering (except in ‘HOLD’-mode) Changing the trigger mode switches the auto range mode immediately off.
_________________________________________________________________________________________________________________________________________________________ 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) 1 G • • • • Fig 43 Remarks: Most of the keyboard functions are disabled.
_________________________________________________________________________________________________________________________________________________________ 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.
_________________________________________________________________________________________________________________________________________________________ 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. G • • Note: Use the reset function in case of unusual behaviour of the unit, like distorted screen or not functional keyboard (see also troubleshooting). Do not use a sharp tool.
_________________________________________________________________________________________________________________________________________________________ TROUBLESHOOTING The screen remains blank or there is no signal: • No power supply • Batteries are discharged • Contrast adjustment is incorrect • Press RESET for at least 10 seconds REMARK: Temporarily remove both batteries and adapter in case RESET is not helping.
