P-83 echo strength (V)
displays the absolute strength of the selected echo in dB above 1 uV rms
P-84 noise
average and peak ambient noise, in dB above 1 uV rms
ambient noise includes acoustical and electrical noise being picked up by
the transducer/receiver circuit when the transmit/receive cycles have been
disabled during the
CALIBRATE
mode

P-85 echo processing algorithms
enter 1 = best echo of first and largest (F)
2 = first echo
3 = largest echo
P-86 TVT curve
enter 1 = standard (F)
2 = flat
typical usage; solids applications where low confidence is obtained,
using flat echo extraction may yield higher confidence.
P-87 range extension
used to extend the measurement range into the far end blanking.
In applications where the zero level does not correspond to the bottom of
the vessel and it is desired to monitor this zone, the far end blanking may
need to be reduced. This is accomplished by entering a range extension
value as the percentage of P-3 which equals the extra distance required.
If it is found that false echoes are appearing ahead of the far end blanking
zone, the range extension should be decreased by reducing the factory
set value of 20%.
enter, as percent of P-3, distance below 0 not blanked (F=20)
P-88 number of transmit pulses
this parameter is used to select the number and duration of the pulses to
be transmitted per measurement.
