are identified as LIMIT 05-08.
13.1.3 Third Channel Installed
The third Relay Output channel installed in an instrument adds
another four limits to the instrument (Limit 9, Limit 10, Limit 11 and
Limit 12). Its relay outputs show the status of these limits.
In the SYSTEM -> CONFIGURATION sub-menu, channels of this type
are identified as LIMIT 09-12.
13.1.4 Fourth Channel Installed
The fourth Relay Output channel installed in an instrument adds
another four limits to the instrument (Limit 13, Limit 14, Limit 15
and Limit 16). Its relay outputs show the status of these limits.
In the SYSTEM -> CONFIGURATION sub-menu, channels of this type
are identified as LIMIT 13-16.
