8. Battery power and external power supply indication.
9. Channel 1 waveform.
10. The pointer indicates the trigger electrical level position of the channel.
11. Channel 2 waveform.
12. The icon indicates trigger-related information, including trigger channel,
coupling mode, trigger type and trigger electrical level. For details, please
refer to P18 Trigger System.
13. The current sampling rate.
14. The channel information reading indicates the voltage position of the
corresponding channel.
The icon indicates the coupling mode of the channel:
"—" means DC coupling
"～" means AC coupling
" " Means ground coupling
15. The pointer indicates the grounding reference point (zero position) of the
waveform displayed in CH2 channel. If there is no pointer indicating the
channel, it means that the channel is not open.
16. The pointer indicates the grounding reference point (zero position) of the
waveform displayed in CH1 channel. If there is no pointer indicating the
channel, it means that the channel is not open.
17. Waveform display area.
Functional Check
Making a quick functional check to verify that the instrument is working
properly. Please proceed as follows:
1. Press the switch at the bottom left of the main unit .
The internal relay will make a slight click. The instrument executes all
