Channel Monitor
The channel monitor function of M300 allows users to monitor a single channel,
multiple channels, or all of the channels in the scan list. The instrument monitors the
channel and takes readings from the channel monitored continuously even during a
scan. This function is helpful for troubleshooting your system before a test or for
watching an important signal.
The channel monitor function can monitor the following channels: multiplexer
channels (configured to the scan list and the DMM module is enabled), DIO and TOT
channels of the multifunction module (no matter whether they are configured to the
scan list and the DMM module is not required).
Press Monitor at the front panel to configure the channel monitor function.
Single-channel Monitor
Press Monitor  Single to enter the single-channel monitor interface as shown in
Figure 2-12 and by default, the first channel in the scan list is monitored. If no scan
list is currently configured, the first channel of the multifunction module (DIO
channel) is monitored.
