5-3.Adjustments and checks
Trace Rotation Adjustment
Normally, when the trace is in parallel with the center horizontal graticule line,
there will be no need to adjust the TRACE ROTATION. If necessary, adjust the
TRACE ROTATION to make the baseline trace parallel to the center horizontal
graticule line by using a small straight-blade screwdriver or alignment tool.
Probe Compensation
To minimize the distortion of measured waveforms, check the compensation of
your probes before using them. The probe compensation should be checked
periodically whenever the probes are moved to different input channels.
1. Install the probes onto the oscilloscope (Press the BNC connector onto the
channel input and rotate the connector to lock it into place).
2. Set the probe slide switches to the ×10 position.
3. Briefly pressing the CH1/CH2 button to set the oscilloscope to channel 1 and
channel 2.
4. Pressing and holding the P×10 button to set the indicated deflection
coefficient of the channel displayed in the readout as a symbol “P10”.
5. Attach the probe tips to the CAL connection in the front of the oscilloscope.
6. Set the oscilloscope controls to display both channels:
VERTICAL: VOLTS/DIV 0.2V
COUPLING DC
ALT/CHOP CHOP
HORIZONTAL:
TIME/DIV 0.5ms
TRIGGER: MODE ATO

7. Observe the displayed waveform and compare them with the waveforms
shown in figure 5-2. If either probe needs to be adjusted, proceed the step 8. If

either probe does not need to be adjusted, proceed the “Function Check”.

8. Adjust the probe by using a small insulated screwdriver. Slowly rotate the
adjustment control until the probe is properly compensated.
