5. Using Loop Test, enter current value (mA) representing low alarm current. Verify that
analog output current and terminal voltage are correct using reference meters.
This step tests for possible quiescent current related failures.
6. Enable write protection.
7. Inspect the transmitter for any leaks, visible damage, or contamination.
8. Perform a two-point calibration check of the device by verifying level output for two
points on the probe within 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
The applied level has to be between upper and lower range values, otherwise the device enters
alarm mode. If level is outside maximum measuring range, the level reading accuracy may be
reduced. For best performance, use the 4-20 mA range points as calibration points. See Figure
6-2 for range values.
