Use Of Probe Check Wizard; Manual Probe Compensation - Hantek DSO4072 User Manual

1.3.2 Use of Probe Check Wizard

Every time you connect a probe to an input channel, you should use the probe check wizard to
verify that this probe is operating correctly.
Use the vertical menu (for example, push the CH1 MENU button) to set the Probe option
attenuation factor.

1.3.3 Manual Probe Compensation

Upon the first connection of a probe and an input channel, you should manually perform this
adjustment to match the probe to the input channel. Uncompensated or miscompensated probes
may lead to errors or faults in measurement. To adjust the probe compensation, follow the steps
below.
1. Set the Probe option attenuation in the channel menu to 10X. Set the switch on the probe to
10X and connect the probe to Channel 1 on the oscilloscope. If you use the probe hook-tip,
ensure it is firmly inserted onto the probe. Attach the probe tip to the PROBE COMP
~5V@1KHz connector and the reference lead to the PROBE COMP Ground connector.
Display the channel and then press the AUTOSET button.
2. Check the shape of the displayed waveform.
3. If necessary, use a nonmetallic screwdriver to adjust the variable capacity of your probe until
the shape of the waveform turns to be the same as the above figure. Repeat this step as
necessary. See the figure below for the way of adjustment.
