Select the signal source for the selected channel. This can be
any external analog or digital signal – see APPENDIX 1 for full
list.
Note. The tabs change according to the selection made.
Note. Setting a channel source to 'None' does
off the analog input to which the channel was assigned
previously – i.e. the analog input continues to be monitored.
To switch off an analog input, set 'Analog I/P Type' for the
required channel to 'Off' – see Section 4.6.2.
The trace color cannot be changed. The trace colors are:

Notes.
• Applicable to analog signal sources only.
• Filters are applied to the recorded values shown on the
chart view only, not to instantaneous values displayed on
the channel indicators or bargraphs.
Instantaneous – A
Average – The average value of the analog signal
Minimum – The minimum value of the analog signal
Maximum – The maximum value of the analog signal
Max/Min – Two values are recorded to capture the
