6. How to Set the Probe Attenuation Coefficient

The probe has several attenuation coefficients, which will influence the vertical scale factor of the oscilloscope.

To change or check the probe attenuation coefficient in the menu of oscilloscope:

1. Press the function menu button of the used channels (CH1 MENU or CH2 MENU).

3. Press H3 button to display the Probe menu; select the proper value corresponding to the probe.

This setting will be valid all the time before it is changed again.

Note: The attenuation coefficient of the probe in the menu is preset to 10X when the oscilloscope

is delivered from the factory. Make sure that the set value of the attenuation switch in the

probe is the same as the menu selection of the probe attenuation coefficient in the

oscilloscope.

The set values of the probe switch are 1X and 10X (see Fig. 10).

Fig. 10 Attenuation Switch

Note: When the attenuation switch is set to 1X, the probe will limit the bandwidth of the

oscilloscope in 5MHz. If it is needed to use the full bandwidth of the oscilloscope, the switch

must be set to 10X.
