4.Using loop test, enter the mA value representing the low alarm mode. Verify that the analog output current is correct using the reference meter. This step tests for possible quiescent current related failures.

AMS: Select Configure / Setup, Analog Output from the menu. Click Loop Test... Select Other and enter the mA value representing the low Analog Output Level and follow the instructions. Click OK to save changes. Verify that the output current is correct.

Select End to stop loop test. Verify that the Current output is restored to the original mode.

5.Perform a two-point calibration check of the transmitter by applying level to two points on the probe 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 Figure E-1 on page E-2.

6.Enable write protection.

AMS: Select Device Diagnostics / Tools from the menu, click Write Protect... and follow the instructions. (Note that the password cannot be written with letters.)

7.Restore the loop to full operation.

8.Remove the bypass from the safety PLC or otherwise restore normal operation.

9.Document the test results for future reference.
