9-2 Relay Comparator Mode
9-2-1 Relay operation mode
In comparator output function, there are 4 modes and measurement value and setting
value is compared and output from relay output terminal (L1, L2, L3) of rear panel.

Only Lo & Hi value setting is available from basic limit mode. OK setting is unavailable.
In other modes, operation is conducted by RY1, RY2, and RY3 setting value.
