Trigger System
The trigger determines when the oscilloscope begins to acquire data and display a
waveform. Once a trigger is properly set up, the oscilloscope can convert unstable
displays or blank screens to meaningful waveforms.
The triggering mode of this series oscilloscope is edge trigger.
Edge trigger distinguishes the trigger points by seeking the specified edge (rising, falling,
rising & falling) and trigger level.
Trigger Source: Select the trigger source signal to CH1 or CH2. You can use the trigger
source options to select the signal that the oscilloscope uses as a trigger.
Trigger Mode: You can select the Auto or Normal mode to define how the oscilloscope
acquires data when it does not detect a trigger condition. Auto Mode performs the
acquisition freely in absence of valid trigger. It allows the generation of untriggered
waveforms with the time base set to 100ms/div or slower. Normal Mode updates the
displayed waveforms only when the oscilloscope detects a valid trigger condition. Before
this update, the oscilloscope still displays the old waveforms. This mode shall be used
when you want to only view the effectively triggered waveforms. In this mode, the
oscilloscope displays waveforms only after the first trigger.
Trigger Level: It sets the amplitude level the signal must cross to cause an acquisition
when using the Edge or Pulse Width trigger. Press Trig button to enter, and press Up or
Down direction keys to change the trigger level.
Force Trigger: Used to complete an acquisition regardless of an adequate trigger signal.
This button becomes useless if the acquisition is already stopped.

Measurement
Scale measurement
Graticule: This method allows you to make a quick, visual estimate and take a simple
measurement through the graticule divisions and the scale factor.
For example, you can take simple measurements by counting the major and minor
graticule divisions involved and multiplying by the scale factor. If you counted 6 major
vertical graticule divisions between the minimum and maximum values of a waveform and
knew you had a scale factor of 50mV/division, you could easily calculate your
peak-to-peak voltage as follows:
6 divisions x 50mV/division = 300mV.

signal output. The output waveform of the signal generator can be observed through
an oscilloscope.
For example, set a sine waveform with 2Vpp@10KHz to output as follows:
The waveform observed by an oscilloscope is as follows:
Troubleshooting
1. If the oscilloscope does not start up at power on, follow these steps:
1） Check whether the battery is installed and confirm whether the battery level is enough.
2） If the battery level is not enough, use the power adapter to charge.
3） Restart the instrument after the battery level is enough.
4） Contact your local HANTEK distributor or directly keep touch with HANTEK Technical
Support department if the oscilloscope still can not be turned on normally.
2. If there is no display of waveforms on the screen when the oscilloscope is
turned on, follow these steps:
1） Check the probe to assure its proper connection to the input BNC;
2） Check the channel switch (Channel button) to make sure it has been turned on;
3） Check the input signal to verify it has been connected to the probe correctly;
4） Affirm that all measured circuits have signals to output;
5） Turn up the magnitude for DC signals with large magnitude;
6） In addition, you may press the Auto button to perform an automatic detection of
signals at first.
7） Contact HANTEK Technical Support department in time if there is still no display of
waveforms.
3. If the waveform of the input signal is distorted seriously, follow these steps:
1） Check the probe to assure its proper connection to the channel BNC;
2） Check the probe to assure its good connection to the measured object;
3） Check the probe to verify it has been well calibrated. Otherwise, refer to the content
about calibration described in this manual.
4. If the waveform is rolling continuously on the screen but can not be triggered,
follow these steps:
1) Check the trigger source to make sure it consistent with the input channel;
2) Check the trigger level to assure its correct adjustment. You may press TRIGGER
button to enter trigger menu, and use Up, Down, Right, Left direction keys to adjust
trigger level to return to signal.
General Care and Cleaning
General Care
Do not put or leave the device in a place where the LCD display will be exposed to direct
sunlight for long periods of time.
Note: To avoid damage to the oscilloscope or probes, do not expose them to sprays,
liquids, or solvents.
Cleaning
Examine the oscilloscope and probes as often as operating conditions require. To clean
the exterior surface, perform the following steps:
1） Use a lint-free cloth to remove floating dust on the outside of the oscilloscope and
probes. Take care to avoid scratching the glabrous display filter.
2） Use a soft cloth dampened with water to clean the oscilloscope. For more efficient
cleaning, you may use an aqueous solution of 75% isopropyl alcohol.
Note: To avoid damage to the surface of the oscilloscope or probes, do not use any
corrosive or chemical cleaning agents.
