The SIGNL Option(cont.)
The percentage of peak used to calculate the transit times and Delta T
is specified at this prompt. The default value for this parameter is
50% and values from 1 to 100% are acceptable.
Both the upstream and downstream transducers transmit ultrasonic
pulses in bursts, which consist of a series of transmit pulses.
XMIT
SAMPLE SIZE determines how many bursts are sent in one direction
before sending in the other direction. The default value for this
parameter is 8 and values of 2, 4, 8, 16 and 32 are acceptable.
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.The default value for this parameter is 50
µ
sec and
values from 0 to 250
µ
sec are acceptable.
