Restore the Alarm mode to the original mode used in the loop. Verify that the analog
output current is correct.
RRM: Set Alarm Mode AOut 1 to original mode. Click Store to save changes.
Verify that the output current is correct.
Perform a two-point calibration check of the transmitter by applying level at two points
within the measuring range. Verify that the current output corresponds to the level
input values using a known reference measurement.
This step verifies that the analog output is correct in the operating range and that the
Primary Variable is properly configured.
Note that the applied level has to be between the Upper and Lower Range values,
otherwise the transmitter enters alarm mode. If the applied level is outside the
Maximum Measuring Range, the level reading accuracy may be reduced. For best
performance, use the
4-20 mA range points as calibration points. See
Enable write protection.
RRM: Select Tools, Lock / Unlock Configuration Area from the menu.
Restore the loop to full operation.
Remove the bypass from the safety PLC or otherwise restore normal operation.
Document the test results for future reference.
