Notes:
1 «Relay 3: Gas alarm» is the only function of relay 3 in all software versions
prior to 6.1c1 (check with your distributor or SERVOMEX if in doubt about the
SW version of your instrument)
2 «Last» means the last valid measurement concentration before an error
occurred.
3 Relays 1 (Error), 2 (Warning) are set as for rows 3-6 independent of the input
switch of Normal/Maintenance/Zero/Span.
4 If relay 3 is configured for «Gas Alarm» this relay is set as for rows 3-6
independent of the input switch of Normal/Maintenance/Zero/Span, otherwise
maintenance mode is indicated.
5 When entering sleep (fault) mode, relay 3 is set according to measuring mode
immediately before. The state of relay 3 does not change even if attempting to
change measuring mode while in sleep mode.
