4. Wait while the meter collects and analyzes process data.
This step should be complete in approximately 20 seconds.
5. Check the results in the
Results
data display.
•
If all process variables passed the tests, no action is required. Select
Close
to exit the wizard.
•
If one or more process variables failed the test:
—
For problems with Line Temperature, verify that the ambient temperature of the meter is stable,
and that the meter temperature has stabilized in the test location. Then retry the Known Density
Verification procedure.
—
For problems with Verification Time Period Signal or Drive Gain, ensure that the meter is clean
and dry. Then retry the Known Density Verification procedure.
—
If the Known Density Verification procedure continues to fail, contact customer service.
14.4 Check power supply wiring
If the power supply wiring is damaged or improperly connected, the transmitter may not receive enough
power to operate properly.
Prerequisites
You will need the installation manual for your transmitter.
Procedure
1. Use a voltmeter to test the voltage at the transmitter’s power supply terminals.
•
If the voltage is within the specified range, you do not have a power supply problem.
•
If the voltage is low, ensure that the power supply is adequate at the source, the power cable is
sized correctly, there is no damage to the power cable, and an appropriate fuse is installed.
•
If there is no power, continue with this procedure.
2. Before inspecting the power supply wiring, disconnect the power source.
CAUTION
If the transmitter is in a hazardous area, wait five minutes after disconnecting the power.
3. Ensure that the terminals, wires, and wiring compartment are clean and dry.
4. Ensure that the power supply wires are connected to the correct terminals.
5. Ensure that the power supply wires are making good contact, and are not clamped to the wire
insulation.
6. Reapply power to the transmitter.
CAUTION
If the transmitter is in a hazardous area, do not reapply power to the transmitter with the housing
cover removed. Reapplying power to the transmitter while the housing cover is removed could
cause an explosion.
7. Test the voltage at the terminals.
