F.3.33 Pulse repeat (P041)
The nominal rate of repetition for ultrasonic pulses from the transmitter is one pulse per second.
If two transmitters were located within the same tank, it is possible this would allow ultrasonic
pulses from one unit to be received by the other. This can be prevented by having both
transmitters operate with different rates of pulse repetition, which means this interference is
rejected as not consistent (pulse-to-pulse). Pulse Repeat allows the pulse repetition interval to
be adjusted by increments of 0.1 seconds.
This parameter is not available in the 3100 Series DD (Device Descriptor) file. However, it can be
adjusted using the integral buttons (see "Setting the pulse repetition frequency (on the 3102/3105)"
on page 67).
