Frequently Asked Questions - HPS140 VELLEMAN

How do I charge the battery of the HPS140 oscilloscope?

Use the included USB charger by connecting it to a USB port (5 V/500 mA) or a 9 VDC/200 mA power adapter. Full charging time is about 6 to 7 hours. The charging LED lights up during charging.

What is the maximum input voltage of the oscilloscope?

The maximum allowed voltage on the BNC input is 100 Vp (peak) AC+DC. Never exceed this value to avoid damaging the device.

How do I use the display hold function (Hold)?

Briefly press the HOLD button to freeze the signal on the screen. To save the frozen data, hold the button down until MEM1 appears. The data is stored in MEM1 or MEM2 if the first is full. Press briefly again to unfreeze.

How do I set the probe to x10 mode?

In the detailed menu (hold the MENU button), select the probe configuration option and choose x10. You can also adjust probe compensation using the test signal (point 13 on the panel).

How do I measure voltage with the oscilloscope?

Connect the probe to the BNC input. The oscilloscope starts in automatic mode. Use the abbreviated menu (brief press of MENU) to set the volt/div or select AUTO. Choose AC/DC coupling according to the signal. Voltage markers (U1, U2) allow precise measurements.

What is the battery life?

After a full charge, the battery life can reach up to 6 hours of continuous use. This depends on the backlight usage and settings.

How do I use the time and voltage markers?

After freezing the display (HOLD), briefly press MENU to access the abbreviated marker menu. Use the UP/DOWN keys to move U1, U2 (voltage) and t1, t2 (time). The detailed menu (hold MENU) allows switching between time and frequency for the markers.

How do I save a waveform to memory?

First freeze the signal with the HOLD button. Then hold the HOLD button until MEM1 appears. The waveform is saved in memory 1. If it is already full, it will be saved in memory 2. The data remains even after power off.

What accessories are included with the HPS140?

The HPS140 comes with a USB charger. The HPS140i model additionally includes an isolated measuring probe PROBE60S (x10 attenuation). The NiMH battery (BPHPS140) is built-in.

How do I clean the oscilloscope?

Use a soft, dry cloth to clean the case and screen. Never use chemicals, solvents, or abrasive liquids. Disconnect the device before cleaning.

OVERVOLTAGE / INSTALLATION CATEGORIES

CAT II: A CAT II-rated meter is suitable for measurements on mono-phase appliances that are connected to the mains by means of a plug and circuits in a normal domestic environment. E.g. household appliances, portable tools...

Provided that the circuit is at least 10m apart from a CAT III- or 20m apart from a CAT IV-environment.

POLLUTION DEGREE

Pollution degree 2 : Only nonconductive pollution occurs. Occasionally, temporary conductivity caused by condensation is to be expected.(home and office environments fall under this category).

During use

• Never exceed the limit values for protection. These values are listed in the specifications.
• Do not touch unused terminals when the unit is linked to a circuit which is being tested.
• When carrying out measurements on a TV set or switching power circuits, always remember that the meter may be damaged by high amplitude voltage pulses at test points.
• Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep your fingers behind the probe barriers at all times during measurement.
• Use a measuring probe with an insulated connector when measuring voltages exceeding 30V.
• For X10 probe: Match the frequency response to the oscilloscope input by adjusting the compensation trimmer on the probe, see probe manual

Charging the oscilloscope

The are several charging options: Use the included USB charger, plugged into a computer USB port, a mains to USB adaptor, a car 12V to USB adaptor or any USB type socket that can supply 5V/500mA. For measurements during charging, it is strongly advised to use a 9Vdc/min 200mA mains adaptor.

Charging of completely drained batteries can take up to 7 hours. The charge LED indicator will light while the scope is charging.

Quick use of the oscilloscope

After turning ON, a start-up screen appears. During this time, some calibrations are performed, so it can take a few seconds before the oscilloscope is ready for use.

The scope always starts in full auto set-up mode. This mode can be used for most (repetitive) signals. Set the input coupling to "DC" if very low frequencies or DC voltages are measured (see further).

SHORT MENU > access by briefly pressing the menu button

The short menu is used to change the most common parameters like volts per division or time-base. For more advanced functions, the extended menu can be used.

Briefly press the menu button to select and highlight the desired parameter

Parameters in reverse= automatic mode.

Enlarge or reduce the signal vertically by adjusting the voltage per division, or select 'AUTO' for automatic signal display

Adapt the scope readout to the probe setting "x1" or "x10"

Time base: More or less signal cycles will be visible by modifying the time per division, or select 'AUTO' for automatic signal display

Select the input coupling AC / DC or choose a zero reference level (GND)

Select the desired voltage readout (Volt, dB, audio power measuring...)

Note: The menu will exit automatically if no button is pressed for a few seconds, or exit by a long press on the menu button.

Hint: In most settings, hold the UP or DOWN button pressed to activate the auto-range function.

EXTENDED MENU > access by keeping the menu button pressed

Briefly press the menu button to select and highlight the desired parameter

graph TD
    A["Select the desired trigger mode (run, normal)"] --> B["Select the triggering at a falling or rising edge of the input signal"]
    B --> C["Adjust the trigger level"]
    C --> D["Move the signal vertically over the display (Y scroll bar)"]
    D --> E["Move the signal horizontally over the display (X scroll bar)"]
    E --> F["Increase or decrease the contrast until the desired contrast is reached"]

Note: The last selected extended menu option will appear in the short menu, until an other parameter is selected.

'Hold'-function

The scope has two memories and one hold screen. The two memories are stored even after power off. Press the 'hold'-button briefly to freeze the screen

To store:

1- Press and keep the 'hold'-button to store the frozen screen until MEM1 appears
2- Your signal is stored in MEM1, if a signal was previous stored, this signal is moved to MEM2
3- Press the 'hold'-button briefly to release the screen for measurements
