Testing before commissioning It is recommended that after receiving a new oscilloscope, a check of the unit is carried out as follows: 1. check if the unit has been damaged during transport. If you find that the cardboard packaging or the protective foam pads are badly damaged, save them until the entire unit and its accessories have passed the electrical and mechanical test. 2. checking the accessories The accessories supplied are described in Appendix B "Accessories" of this manual.
Probe compensation When you connect the probe to an input channel for the first time, you must adapt the probe to the input channel. An uncompensated or incorrectly compensated probe will result in measurement errors. Perform the probe compensation as follows: 1. Set the damping factor of the probe to 10X in the menu, also set the switch on the probe to 10X and connect the probe to channel 1. When using the hook tip, make sure that it remains securely connected to the probe.
Setting the probe damping factor The probe has several probe damping factors that affect the vertical scaling factor of the oscilloscope. If the set probe attenuation factor is to be changed or checked, press the function menu key for the respective channel and then the selection key corresponding to the probe until the correct value is displayed. This setting remains valid until it is changed again. Note: The damping factor of the probe in the menu is preset to 10X at the factory.
Self-calibration With the auto-calibration, the oscilloscope can be quickly set to the optimum state for highly accurate measurements. You can run this programme at any time, but you must do so if the ambient temperature varies by more than 5°C. Remove all probes and cables from the input sockets before performing the auto-calibration. Press the "UTILITY" button, then the "H1" button to enter the FUNCTION menu; turn the "Multipurpose" knob to select "Adjust".
Set the vertical offset to 0 again: Turn the VERTICAL POSITION knob to change the vertical position of the channel and press the VERTICAL POSITION knob to reset the vertical position to 0. This is especially useful if the position track goes far out of the display area and the signal should immediately reappear in the centre of the screen. 2.

4. User instructions (for advanced users) In the preceding paragraphs, the user has already been familiarised with the basic functions of the function areas, keys and buttons on the front panel of the oscilloscope. Based on the introduction of the previous chapter, the user should already have gained first insights into changing the oscilloscope settings, selecting and evaluating the status bars and general operation.
Adjust vertical system The VERTICAL functions include 5 menu buttons such as CH1 ～ CH2 (2CH models) and Math, and 8 rotary controls such as VERTICAL POSITION, VOLTS/DIV for each measuring channel. Settings CH1 ～ CH2 Each channel has an independent vertical menu with functions based on that channel. Switch waveform display on/off (CH & Math function) Pressing the CH1 ～ CH2 or Math buttons has the following effect: - If the waveform is switched off, it is switched on and the channel menu is displayed.
1. Set channel coupling For example, to represent channel 1 with a square wave signal on a DC coupling basis, proceed as follows: (1) Press the CH1 button to display the channel menu. (2) Select Coupling in the lower menu. (3) Select DC in the right-hand menu. DC and AC components are thus recorded. (4) Alternatively, select AC in the right-hand menu. DC components are now blocked. 2.
Mathematical function The mathematical functions are used to display measuring channels added, subtracted, multiplied or divided. Alternatively, the FFT function can be activated.
User defined function Press the Math button to display the Math menu below. Select User Function in the bottom menu, an expression input keyboard appears. 3. create a representation. When you are finished, select on the keyboard to confirm. The division of the Math waveform is displayed at the bottom left of the screen. FFT function The FFT (Fast Fourier Transformation) function converts a time-based waveform into its individual frequency components.
Select FFT window ■ There are six FFT windows. Each window makes trade-offs between frequency resolution and amplitude accuracy. Choose the window based on what you want to measure and the characteristics of your source signal. The following table will help you choose the best window: Art Rectangle (Rectangle) Hanning Characteristics This window is best for frequency resolutions, but is the worst for accurately measuring the amplitude of these frequencies.
Notes for FFT use The waveform zoom function also works for FFT. Use the dBV RMS scale for a detailed view of multiple frequencies, even if they have different amplitudes. Use the linear RMS scale to compare all frequencies in an overall view. Signals that contain a DC component or offset can lead to incorrect FFT signal amplitude values. To minimise the DC component for the source signal, select AC coupling.
Set horizontal system The HORIZONTAL CONTROLS consist of the HORIZ-MENU button and adjustment knobs such as HORIZONTAL POSITION and SEC/DIV. 1. adjustment knob HORIZONTAL POSITION: with this adjustment knob you control the horizontal positions of all channels (including those created by mathematical calculation) whose resolution changes with the time base. 2. setting knob SEC/DIV: with this you set the horizontal scale factor with which you determine the main time base or window. 3.
Set trigger system The trigger determines when the oscilloscope starts acquiring data and displaying the waveform. Once set correctly, the trigger can convert a fluctuating display into a meaningful waveform. When the oscilloscope starts acquiring data, it records enough data to display the waveform to the left of the trigger point. The oscilloscope continues to record data while waiting for a trigger condition.

For a quick display of this signal, proceed as follows: 1. Set the probe attenuation to 10X in the menu and also to 10X with the switch on the probe. 2. Connect the probe of CH 1 to the desired measuring point. 3. Press the AUTOSET button.
Now the measured values (period, frequency, average value and peak-to-peak voltage) are automatically displayed in the lower left corner of the screen. Example 2: Measuring the gain of an amplifier Set the probe attenuation to 10X in the menu and also to 10X with the switch on the probe. Connect CH1 of the oscilloscope to the signal input of the circuit and CH2 to the output. Operation: 1. Press the Autoset button; the oscilloscope automatically makes the correct setting of the two channels. 2.
Example 3: Measurement of a single signal With the digital oscilloscope it is quite easy to record a non-periodic signal such as a pulse or a signal peak etc.. However, the general problem is how to set up a trigger if you do not know the signal? For example, if the pulse is a TTL logic signal, you should set the trigger level to 2 V and set the trigger edge to the rising edge. Since our oscilloscope supports various functions, the user can solve this problem quite easily.
Example 4: Detailed signal analysis Most electronic signals have noise. This oscilloscope provides the very important function of determining what is in the noise and reducing the noise level. Noise analysis The noise level sometimes indicates a fault in the electronic circuit. You can find out more about this noise using the Peak Detect function. To do this, proceed as follows: 1. Press the Acquire button to enter the Acquire menu. 2. Press the Acqu Mode button to display the menu. 3.
Example 5: Application of the X-Y function Examining the phase difference between the signals of both channels Example: Testing the phase change of a signal after passing through a circuit. The X-Y mode is very useful for checking the phase shift of two connected signals. This example shows you step by step how to check the phase change of the signal after it has passed through a certain circuit. The input and output signals of the circuit are used as source signals.
Example 6: Video Signal Trigger Observe the video circuit of a TV, apply the video trigger and get the stable video output signal display. (1) Press the trigger menu button to display the trigger menu. (2) Select the first menu item in the bottom menu. Select Single in the righthand menu. (3) Select Video as the mode in the left menu. (4) Select Source in the bottom menu. Select CH1 in the right menu. (5) Select Modu in the bottom menu. Select NTSC in the right menu. (6) Select Sync in the bottom menu.
10.technical specifications Unless otherwise stated, the technical data apply only to oscilloscopes with a set probe attenuation of 10X. The technical data only apply if the oscilloscope fulfils the following two conditions: at least The unit should run continuously for 30 minutes. Perform "self-calibration" if the operating temperature changes by up to or even more than 5℃ (see "Performing self-calibration"). All technical data, with the exception of those marked "typical", can be met.
