DPO6000, MPO6000 Series Digital Fluorescent Oscilloscope Product Manual V1.3

2. No waveform is displayed on the input signal screen after the oscilloscope is
turned on.
(1) Check whether the oscilloscope probe is correctly connected to the BNC connector
of the signal input channel.
(2) Check whether the channel switch is on (CH1～CH4 menu button).
(3) Check whether the input signal is correctly connected to the probe.
(4) Check if there is signal output from the measured circuit.
(5) If it is a DC signal and the amplitude is relatively large, please increase the ampli-
tude.
(6) You can press the automatic measurement button to automatically detect the signal
first.
If there is still no waveform display, please contact Hantai Technical Support in time.
3. The input signal waveform distortion is serious
(1) Check if the oscilloscope probe is connected to the channel BNC connector.
(2) Check whether the probe is well connected with the measured object.
(3) Check whether the oscilloscope probe is calibrated properly. If there is no calibration,
please calibrate according to the relevant content in the manual.
4. The waveform continuously scrolls on the screen and cannot be triggered.
(1) Check whether the trigger data source is consistent with the signal input channel.
(2) Check whether the trigger level is adjusted correctly. You can press the trigger level
knob to return the trigger level to the signal center point.
(3) Check whether the trigger mode is correct, because the default trigger is edge trig-
ger. For different input signals, the trigger mode should be selected correctly.
Technical specifications
All technical specifications are applicable to the DPO600 / MPO6000 series digital stor-
age oscilloscopes. For details, see the last part of this chapter. To verify that the oscillo-
scope meets the technical specifications, the oscilloscope must first meet the following
conditions:
➢ The oscilloscope must have been working continuously for more than 20 minutes
within the specified operating temperature.
➢ If the operating temperature changes by more than 5 degrees Celsius, you must
perform the “self-calibration” operation. This operation can be performed through
the [Utility] menu.
