Chapter 4. Printing Data
68 DigitalFlow™ GF868 Programming Manual (1-Channel)
4.7 Printing Signal Array Data (cont.)
The data printed using the SIGNL submenu consists of 1024 lines, each of which lists the following three values:
• Index - this is the printout line number, which locates the data point within the complete body of data.
• Upstream - this is the amplitude of the signal from the upstream transducer at the listed index number.
• Downstream - this is the amplitude of the signal from the downstream transducer at the listed index number.
Note: The printouts generated from the
CROSS and BOTH submenus will appear after the SIGNL printout, as separate
listings.
The data printed in this array permits a comparison of the relative signal strengths of the upstream and downstream
transducers, which are used to calculate a single flow measurement.
4.8 Printing RTD Data
Use the RTDs submenu to send the numeric point value of a connected RTD device to the RS232 port for display on a
terminal or RS232 printer. By viewing the point value of the meter at a given temperature, you can calculate the points
at the Set Temperature, and the slope of the RTD input in points/degree. (See Chapter 1, Calibration, of the Service
Manual for more details.)
1. To access the Print Menu, press the [PRNT] key.
Note: The Print Menu is not protected by the security feature and a password is never required to access this menu.
2. Press the [ or [ key to display the option bar shown, and then press [F3] to select the RTDs submenu.
3. At the Dump RTD Data prompt, press [F1] to leave the PRINT menu without dumping data, or [F2] to send the RTD
data to the RS232 port.
After the selection has been made, the Model GF868 returns to the standard data display screen and normal
measurement taking. If you have selected YES at the DUMP RTD DATA prompt, the meter continues to send data until you
reenter the PRINT menu and select the STOP option.
