1.8.2 Initializing Setup Parameters - Default Setup

Use this option to initialize (reset) all of the parameters within the
following steps to reset all of the parameters:
1. In the Keypad Program, scroll to PROG and press [Enter].
2. In the PROG menu, scroll to CH1 or CH2 and press [Enter].
3. In the Channel PROGRAM menu, scroll to Setup and press [Enter].
4. Scroll to INIT. Press [Enter].
5. Scroll to Yes to initialize default parameters or No to abort this command. Press [Enter].
Procedure Options
After completing the above steps, the XGS868i returns to the Channel Set up window. Do one of the following:
•
To continue programming, refer to Appendix A, Menu Maps, to navigate to the desired menu.
To leave the Keypad Program, press [Escape] four times.

Default
Value
If the burst mode is set to Skan/Measure (S/M), the meter switches from Skan
50 μsec to Measure Mode when Delta T is less than the M>S_Switch value. DO NOT
change this value unless advised by the factory.
The number of shifts corresponds to the actual number of transmits per
cycle (number of signals added together in one direction to produce an
3
averaged signal for one interrogation of the fluid) and need only be changed
if the environment is very noisy or the acoustic signal is weak.
The Divisor used to calculate the Measure Mode integrated threshold level is
2.5
not normally changed.
# Transmit Pulses specifies the number of pulses in a burst. For difficult con-
4 ditions (i.e. long paths, high velocity or high temperature), settings as high as
16 may be necessary.
The XGS868 calculates the size of the transmit window based on pipe size
0
and fluid sound speed. However, for special diagnostic purposes, it is
possible to reset the window size.
The XGS868 calculates the size of the receive window based on pipe size and
10
fluid sound speed. However, for special diagnostic purposes, it is possible to
reset the window size.
