To Compensate the Probes 
Perform this adjustment to match the characteristics of the probe and the channel 
input. This should be performed whenever attaching a probe to any input channel at 
the first time. 
 
1.    From CH1 menu, set the Probe attenuation to 10X (press CH1→Probe→10X). 
Set the switch to 10X on the probe and connect it to CH1 of the oscilloscope. 
When using the probe hook-tip, inserting the tip into the hook-tip firmly to 
ensure a tight connection. 
Attach the probe tip to the connector of the Probe compensator and link the 
reference wire cramp with the ground connector of the probe compensator, 
Select CH1, and then press AUTO. 
 
2.    Check the shape of the displayed waveform.

3.  If necessary, use a non-metallic tool to adjust the variable capacitor of the probe 
for the flattest square wave being displayed on the oscilloscope.   
 
4.  Repeat if necessary. 
 
 
WARNNING: To avoid electric shock while using the probe, be sure the 
perfection of the insulated cable, and do not touch the metallic portions of 
the probe head while it is connected with a voltage source.
