6. The waveform displays like ladder:
1) The horizontal time base may be too low, you can
increase it to improve the horizontal resolution so as
to make a good waveform displaying.
2) The lines between the sample points may also
cause ladder-like displaying if the "Type" in menu of
"DISPLAY" is "Vectors". Please turn the "Type" to
"Dots" to solve the problem.
7. USB storage can't be recognized:
1) Check if the USB flash disk can work normally.
2) Check if the USB Device Host can work normally.
3) Make sure the USB disk being used is of flash type,
the instrument does not support USB of hardware
type.
4) Make sure the system format of used USB disk is
FAT32.
5) Restart the instrument and then insert the USB to
check it.
6) If it is still in abnormal use, please contact CA.
8. To Enable Quick-Cal
Quick-Cal can calibrate the measure deviation which
cause by the temperature (if the operating
temperature changes by more than 2 degrees).
If the temperature the DOX3x04 is working at is not
stable, do the following steps:
English
Press the button "UTILITY" on the front panel to
-
enter the UTILITY function menu.
- Press the Next Page softkey to go to the second
page of the UTILITY function menu.
- Press the Quick-Cal to select On.
If the Quick-Cal has been set to On before powering on,
and the current vertical scale is 2mV or 5mV of any
channel, the oscilloscope will perform the quick
calibration procedure when it powers on.
During the calibration, most of the buttons are disabled.
