Probe Compensation 
 
When the probes are used for the first time or when the probe compensation signal 
does not match that shown in Figure 1-10 (refer to “Function Inspection”), you 
should compensate the probes to match the input channels of the oscilloscope. 
Non-compensated or poorly compensated probes may cause measurement error.  
 
The probe compensation procedures are as follows. 
 
1.  Perform steps 1, 2, 3 and 4 of “Function Inspection” in the previous section. 
2.  Check the waveform displayed on the oscilloscope and compare it with the 
waveforms shown in the figure below.

3.  Use a nonmetallic driver to adjust the low-frequency compensation adjustment 
hole on the probe until the waveform displayed is as the “Perfectly compensated” 
in the figure above.
