P837 Auto False-Echo Suppression
Use P837 and P838 together, to set MultiRanger 100/200 to ignore false echoes. Use P838
to set the Auto TVT distance first.
If MultiRanger 100/200 displays a full level, or if the reading fluctuates between a false
high level and a correct level, set P837 to elevate the TVT in this region and to de-
sensitize the receiver from any ‘base noise’ caused by internal transducer reflections,
nozzle echoes, or other vessel false echoes. Set P838 and then P837 (detailed instructions
follow P838).
Notes:
• This function works best when the vessel is empty or nearly empty: use it only if
there is a minimum distance of 2 meters from the transducer face to the material.
• Set P837 and P838 during start up, if possible.
• If the vessel contains an agitator, the agitator should be running.
