e) Click Stop to end loop test.
4. Using Loop Test, enter current value (mA) representing low alarm current. Verify
that analog output current is correct using the reference meter.
This step tests for possible quiescent current related failures.
a) Select Setup Output Analog Out 1 and click Loop test.
b) Enter current value representing low alarm current.
c) Click Start to output current.
d) Verify that analog output current is correct.
e) Click Stop to end loop test.
5. Enable write protection.
a) Select Tools Lock/Unlock Configuration Area.
b) Enter password to lock.
6. Inspect the transmitter for any leaks, visible damage, or contamination.
7. Perform a one-point level measurement verification of the device. Verify the current
level measurement with an independent measurement such as the BPCS level-
sensor or a manual reading.
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 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 8-3.
