• To continue programming the meter, refer to the menu maps in Appendix A of the
Programming Manual and
navigate to the desired menu. Then, proceed to the appropriate section of the manual for instructions.
• To leave the User Program and retain the previous settings, press [EXIT] twice and then press [F1] = NO at the
SAVE prompt. Any programming changes will be discarded and you will be returned to the data display.
• To leave the
User Program and return to measurement mode, press
[EXIT] twice and then press [F2] = YES at
the
SAVE prompt. Your programming changes will be entered into the meter’s memory, and you will be
returned to the data display.
1.7.5 Entering Setup Data
The signal limits and response times for the Model GS868 are specified via the SETUP submenu. While following the
programming instructions, refer to the menu map in Figure 12 on page 84 in Appendix A, Menu Maps. The following
three submenus are included in this section:
•
SIGNL - set the parameters related to the transducer signal
• AVRG - specify the response of the meter to step changes
• INIT - initialize all parameters to default values.
• ADVAN - setting parameters for mass flow and multiple K-factors.
Enter the SETUP submenu by pressing

steps:
Proceed to the appropriate section to program the option selection made at the above prompt. Remember to record
all programmed data in Appendix B,
Data Records.
1.7.5.1 Setting Transducer Signal Limits
Use this option to set the limits for the incoming signal and other parameters affecting the transducer signal. For
example, the programmed signal strength low limit may be used to determine the trigger point for an alarm. Table 5
on page 19 provides a summary of signal upper and lower limits and default values.
Complete the following steps to enter the signal parameters:
1. Press [ENT] to accept the current Signal Low Limit value or enter a new value and press [ENT] .
The default value for this parameter is 20 and values from –20 to 100 are acceptable. The E1: LOW SIGNAL error
message appears when the signal strength falls below the programmed SIGNAL LOW LIMIT value. See the Service
Manual for a discussion of error codes.
2. Press [ENT] to accept the current Cor. Peak Limit value or enter a new value and press [ENT] .
The default value for this parameter is 100 and values from 0 to 500 are acceptable. The E4: SIGNAL QUALITY error
message appears when the signal quality falls below the programmed COR. PEAK LIMIT value. See the Service
Manual for a discussion of error codes.
