Micro Motion CDM100M, Configuration And Use Manual

Page: 148 / 220

a. Attach a frequency counter, oscilloscope, digital multimeter (DMM), or digital
voltmeter (DVM) to the TPS output loop.
b. Compare the reading to the Sensor Time Period process variable at your meter.
Postrequisites
• If the mA output readings are within 200 microamps of each other, you can correct
this discrepancy by trimming the output.
• If the discrepancy between the mA output readings is greater than 200 microamps,
or if at any step the reading was faulty, verify the wiring between the transmitter
and the remote device, and try again.
• If the discrete output readings are reversed, check the setting of Discrete Output
Polarity .
10.5 Status LED states
The status LED on the transmitter indicates whether or not alerts are active. If alerts are
active, view the alert list to identify the alerts, then take appropriate action to correct the
alert condition.
Your meter has one or two status LEDs:
• A status LED on the display (only if your meter has a display)
• A status LED on the board, beneath the meter housing cover
CAUTION!
If your meter is in a hazardous area, do not remove the meter housing cover. Use a different
method to determine meter status.
The status LEDs use colors and flashing to indicate device status.
Transmitter status reported by status LED Table 10-1:
LED state Description Recommendation
Green No alerts are active. Continue with configuration or process meas-
urement.
Yellow One or more low-severity alerts are active. A low-severity alert condition does not affect
measurement accuracy or output behavior.
You can continue with configuration or proc-
ess measurement. If you choose, you can iden-
tify and resolve the alert condition.
Flashing yellow Calibration in progress, or Known Density Veri-
fication in progress. A low-severity alert condition does not affect
measurement accuracy or output behavior.
You can continue with configuration or proc-
ess measurement. If you choose, you can iden-
tify and resolve the alert condition.
