Abstract
An apparatus to determine if an echo signal shown on a multi-echo analog display unit that is produced by an ultrasonic animal backfat measuring and analyzing instrument is an accurate indication of the depth of backfat under measurement. This display unit has a small hand retainable switch to freeze the signal under measurement to allow the analyzing portion of the instrument to send a signal to the display unit to inscribe a graphical overlay indication upon the echo signal. If the overlay indicator passes through the strongest one of the echo signals then the echo signal is thereby identified as being an accurate measurement of the animal backfat. If it does not, this indicates that something has interfered with this signal and it is therefore inaccurate.
