1.6.4 Performance Enhancement

Registers 20 through 33 can be used to enhance the per-

formance of the Model 335 in specific applications.

P20: - - - a Damping

Factory default value for P20 is: 5 (60 seconds).

Parameter register 20 can be used to reduce undesired

fluctuations of the display and output, and enhance per-

formance in turbulent applications.

P22: - - - a Dome top tank compensation

Factory default value for P22 is: 0.

Non-contact ultrasonic transmitters can occasionally

receive two or more echoes when the transducer is mount-

ed in the center of a domed top tank. If the transducer can

not be positioned away from the center of the domed top,

the 335 provides compensation to reduce the effects of

multiple echoes.

P23: - - - a Register P23 is not used with the

Model 335

Factory default value for P23 is: 0.
