1. In case “Bi direction” is set at “Output function”, the setting range is available
with –108 to +108%. Please set the loop test value in +/– percentage based on the
larger flow span within forward and reverse flow span.
2. In case “Auto 2 ranges” is set at “output function”, the loop test setting value
should be set in percentage based on the second range.
