Q1 | The display response to the waveform change is unusually slow. |
Q2 | It takes 30 to 40 seconds for the multimeter to update the capacitor measurement. |
It takes longer time to measure small capacitors. 30 to 40 seconds are normal for measuring 5nF or smaller capacitors. See page93 for capacitance measurement details.
Q3 | The waveform does not appear at all in the display. |
The trigger level might be out of the waveform range. Press the AUTOSET key so that the GDS-122 automatically adjusts the trigger level.
If the trigger mode is Single, press the RUN/STOP key to trigger the waveform or switch the trigger mode to Normal. See page30 for trigger details.
Q4 | The waveform appears in the display but is not stable. |
Configuring the trigger might help you. Please refer user manual page30 for details.
Make sure the trigger source channel matches the input signal.
Make sure the correct trigger type, edge or video, is selected.
Try changing the HF and LF repression in the trigger coupling mode and filtering out high or low frequency noise.
