5. The Intelis meter LCD moves to Test Display Mode.
Note
: When the Intelis meter is in Test Display Mode, FDM can be used to confirm the
meter is in Test Mode.
Recording prover consumption
While the Intelis meter is in Test Mode, the listed operations occur.
1. The Intelis meter records the Test Mode consumption in the index registers.
2. The Intelis meter continues to output an optical pulse.
Note
: While the Intelis is in Test Mode, the LCD refresh rate is more frequent than when
the meter is operating in Normal Mode.
3. The Intelis meter continues to update the normal volume registers.
Exiting Test Mode
The Intelis meter exits Test Mode after it receives a command from the FDM mobile client,
after the proving cable head is removed from the meter, or when the Test Mode timeout is
reached. The following operations occur when the Intelis exits Test Mode.
1. The Intelis meter logs an Exiting Test Mode event.
2. The Intelis meter ends the optical pulse output.
3. The Intelis meter LCD returns to normal display mode.
Note
: Perform a
Get
to verify the Intelis meter is no longer in Test Mode.
Adjusting the Intelis meter calibration
Adjusting the Intelis meter begins when FDM sends the FDM configuration file that contains
the parameters used by the Intelis to calculate correction factors for the flow rates.
Note
: The FDM configuration file values are not the correction factors but parameters that
are the result of the Test Mode ran in the utility meter shop.
The FDM configuration file initiates the following calibration operations.
1. The Intelis meter enters a
Calibration in Progress
state.
2. The Intelis meter calculates correction factors for the assigned flow rate to meet the
calibration parameters.
3. The Intelis meter sends the correction factors to the internal measurement device which
then, calibrates itself.
4. The Intelis meter logs a
Meter Calibrated
event.
5. The Intelis meter moves to a
Calibration Not in Progress
state.
Note
: Perform a
Get
to confirm the status of the calibration process.
