Siemens 200 instruction manual P837 Auto False-Echo Suppression, Values

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.

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.

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).
