figure 16: Peak Detection

Term interpretation

Collecting mode: The oscilloscope transforms the collected analog data into a digital form after

they are gathered in the following three different modes, such as sampling, peak value detection

and averaging values.

Sampling: The oscilloscope takes samples from the signal at a equal time interval to reconstruct

the waveform in this mode, by which the analog signal can be expressed correctly in most cases,

yet, the rapid changes can not be collected between two sampling time intervals, causing the

confusion and loss the narrow pulse in the signal probably.

Peak value detection: The oscilloscope takes samples from the maximum and minimum of

signals in each sampling interval and shows the waveform with the sampled data in this mode,

thus, by which the oscilloscope may collect the possibly lost narrow pulse in the sampling mode

but the noise is obvious.

Averaging values: the oscilloscope collects several waveforms and average over them, and

displays the averaged waveform in this mode, by which the random noise can be reduced.

Duration time: When a new waveform is displayed, the previous waveform shown on the screen

does not disappear immediately only to be displayed for a period of time, that is, the duration time,

by setting which, the waveform can be displayed more continuously and thus a display similar to

that shown by the analog oscilloscope can be achieved.

Roll scan mode: The oscilloscope updates the waveform sampling points by scrolling display

through a screen from left to right in this mode, which is only applicable to the primary time base

setting of above 50ms.

When starting the acquisition of data, the oscilloscope collects sufficient data to draw the

waveform at the left side of the triggering point. With waiting for the triggering condition, the

oscilloscope is gathering data continuously. After a trigger is detected, the oscilloscope gathers

enough data continuously to draw the waveform at the right side of the triggering point.

To make a trigger mode setting, do the following:

1. Press the MENU key and the function menu appears at the right of the screen.

2. Press the MENU ▲ or MENU ▼ key to select TRIG MODE and five items selectable are

displayed at the bottom of the screen.

Term interpretation

Trigger modes: There are three kinds of trigger modes available for this oscilloscope, they are

auto, normal and single shot.

Automatic trigger mode: The oscilloscope can acquire the waveform without any triggering

condition detected in this mode, in which it will be triggered compulsively when waiting for a

specified period of time without any triggering condition ignited When an invalid trigger is enforced，the oscilloscope can not keep the waveform in phase.

Back to previous menu

Normal trigger mode: In this mode, the oscilloscope cannot acquire the waveform till it is

triggered. When there is not any trigger, the oscilloscope will display the origin waveform without

４４

oscilloscope mode.

z Check whether the signal item in the trigger mode menu matches the actually used signal

channel.

z Check on the trigger mode: The edge trigger mode is applicable to the universal single

and the video trigger mode applicable to the video signal. Only when the proper trigger

mode is applied, can the waveform be in stable.

z Try to change the trigger coupling into the HF rejection and LF rejection to filter the HF

or LF noise trigger by the interference.

6. There is no display on the screen when you push down RUN/STOP key

under the oscilloscope mode.

Check whether the trigger mode in the trigger mode menu is in normal or single shot and

whether the trigger level is out of the waveform range.

10.2 Appendix B: Maintenance and Cleaning

10.2.1 Common Maintenance

Do not store or place the instrument in locations where the liquid crystal display (LCD) may be

directly exposed to the sunshine for a long time.

Be careful: Do not make spraying agent, liquid and solvent touch with probes to avoid the

instrument or probe being damaged.

OWON HDS Series Handheld DSO & DMM 10-Appendix

Cleaning

Inspect the instrument and the probe frequently in accordance with operating conditions. Clean the

outer surface of the instrument according to the following steps:

1. Wipe off the floating dust outside of the instrument and the probe by using soft cloth.

When cleaning the LCD, do not scuff the transparent LCD protective screen.

2. Wipe the instrument in power off status by soft cloth that is moist but not dripping. It is

allowed to be cleaned by soft detergent or fresh water. Do not use any abrasive chemical

detergent to avoid the instrument or the probe being damaged.

Warning: Before repowering and reuse, please confirm that the instrument has been

dried out so as to avoid electrical short circuit and personal injury caused by moisture.

10.2.2 Storage of Oscilloscope

If the test tool is to be stored for a long time, it is required to charge the lithium battery before

storage.

Charging the oscilloscope

The lithium battery is possibly not charged when delivery. To make the battery with enough

electric quantity, it must be charged for 4 hours (the test tool must be turned off during charging).

The battery can supply power for 4 hours after being charged completely.

When supplying power by using the battery, a battery indicator is displayed on the top of the

screen to show the consumption condition of electric quantity. The symbols that are possibly

appear include minutes. To charge the battery and power the instrument, connect the oscilloscope using a power

adapter according to Figure 1 to charge the battery. The charging speed can be increased by

turning off the test tool.

Notice

To avoid superheat of battery during charging, the environment temperature is not allowed to

exceed the permissible value given in technical specification.

Note:

No hazard will occur even connecting the charger for a long time, e.g. during a whole weekend.

The instrument can automatically switch to slowly charging status.
