9.1 Loop Test (Test output)
This function enables you to set up any desired value, and to output it from the con-
verter for test. Since this function corresponds to flow rate totalization display and pulse
output, this makes it possible to check operation of individual function.
The test functions of status output are also provided.
• Test outputs take priority of the flow signal.
Do not forget to return to the normal operation mode after the loop test.
• In case "BI DIRECTION" is set at OUTPUT FUNCTION (Parameter No. b10), the
setting range is available -108 to +108. Please set the loop test value in +/- percent-
age based on the larger flow span within forward and reverse flow span.
• In case "AUTO 2 RANGES" is set at OUTPUT FUNCTION (Parameter No.b10),
the loop test setting value should be set in percentage based on the second range.
