Joy-it JT-DMSO2D72 - Function Introduction

You can press Channel button to enter the channel setting menu and select CH1,
and select the Probe option that matches the attenuation factor of your probe.
Make sure that the Attenuation switch on the
probe matches the Probe option in the oscillo-
scope. Switch settings are 1X and 10X.
When the Attenuation switch is set to 1X, the
probe limits the bandwidth of the oscilloscope
to 6MHz. To use the full bandwidth of the oscil-
loscope, be sure to set the switch to 10X.
