1.8.2 Initializing Setup Parameters - Default Setup
Use this option to initialize (reset) all of the parameters within the
Setup
menu to their default values. Complete 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

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.
M>S Switch
0 to 250
μ sec
50 μ sec
If the burst mode is set to Skan/Measure (S/M), the meter switches from Skan
to Measure Mode when Delta T is less than the M>S_Switch value. DO NOT
change this value unless advised by the factory.
# Shifts 0 to 10 3
The number of shifts corresponds to the actual number of transmits per
cycle (number of signals added together in one direction to produce an
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.
A Divisor 0.1 to 10 2.5
The Divisor used to calculate the Measure Mode integrated threshold level is
not normally changed.
# Transmit
Pulses
1 to 16 4
# Transmit Pulses specifies the number of pulses in a burst. For difficult con-
ditions (i.e. long paths, high velocity or high temperature), settings as high as
16 may be necessary.
T Window
(cycles)
0 to 1000 0
The XGS868 calculates the size of the transmit window based on pipe size
and fluid sound speed. However, for special diagnostic purposes, it is
possible to reset the window size.
R Window
(cycles)
10 to 128 10
The XGS868 calculates the size of the receive window based on pipe size and
fluid sound speed. However, for special diagnostic purposes, it is possible to
reset the window size.
