Makeup

The Test Facility Makeup routine allows you to command the meter to re-acquire the operating param-
eters established during the Initial Makeup routine invoked by the [Install Completed?] command (see
Pick/Install Xdcr).

4.11.8 TROUBLESHOOTING TIPS

The FUG1010GCN has highly reliable circuitry and will provide trouble-free operation within specified
environments. Even a well-crafted precision instrument can fail if exposed to extreme temperature or
vibration conditions during service, storage or transportation. The Diagnostic menu shows how the sys-
tem interprets a problem. The test functions and alarm indicators identify "hidden" problems automatic-
Measured flow rate in selected flow units.
Sound Velocity in meters per second.
Represents the digital sample position of the receive window.
Displays the receive waveform in its proper superposition or registra-
tion. The true delta time will be displayed by NOT selecting "Corre-
lated Plot".
Indicates with a large vertical marker the peak energy of the receive
waveform.
Displays the minimum and maximum digital damping exponent along
with the active damping exponent.
Receive signal transit time in microseconds.
Transit time delta (difference) in nanoseconds.
Displays %Valc (amplitude), %Vaer (aeration factor) and numeric ALC.
Indicates the signal to noise ratio of the receive signal. Increased
damping will increase the S/N ratio as the asynchronous noise reduces.
Percentage change of the signal from Initial Makeup conditions.

HOT KEY SUMMARY

Expands (magnifies) waveform to view more detail.
Contracts waveform to view more or the waveform.
Shifts receive window to the left (waveform to the right).
Shifts receive window to the right (waveform to the left).
Brings waveform to the center of the screen.
Calls up Text Display menu items. <Left Arrow> to return to graph.
Exits the Graph Screen and returns to the main menu.
MinDamp Minimum damping exponent control (+ or - to increase or decrease).
MaxDamp Maximum damping exponent control (+ or - to increase or decrease).
TnSet Transit time adjustment (use + or - to move Tn marker).
ZCOSet Zero Crossover adjustment (use + or - to move crossover marker).
HiSet Signal envelope threshold level (use + or - to move threshold).
LoSet Signal envelope threshold level (use + or - to move threshold).
MaskSet Leading edge masking functions (use + or - to alter number of samples
masked).
Hold Set Set this number higher if intermittant mis-registration occurs.
Exits the command line.
Toggle graph between receive waveform and envelope waveform.
Dumps the digitized waveform data over the RS232 port. You must first
leave the Graph Screen mode before invoking this command.
