[MinDamp #] Command
Pressing the <1> key will cause [MinDamp #] to appear on the command line at the lower
left-hand corner of the screen. The number listed to the right of the command code
represents the exponent in the meter exponential averaging routine, where the larger the
number the greater the digital averaging. Pressing the <+> key will increase the damping
value. Likewise, pressing the <-> key will decrease the damping value.
To exit this mode, press the <0> key on the keypad.
[MaxDamp #] Command
Pressing the <2> key will bring up the [MaxDamp #] command. The function of this
parameter is similar to the [MinDamp #] command described above; however, the two
parameters interact in the following manner. The MinDamp value must not exceed the
MaxDamp value; therefore increasing the MinDamp value above the previous MaxDamp
value will set both parameters to the same value. In most cases, it is preferred that both
damping parameters be set to the same value, however, in cases where rapid response to
changes in liquid sound velocity for flow rate is required, the two values may be set
differently. In this situation the meter will use the MaxDamp value when conditions are
stable, but then switch to a faster damping value (limited by MinDamp) when a significant
change in sound velocity or flow rate is perceived.
To exit this mode, press the <0> key on the keypad.
To access the Digital Damping Control using the Test Facilities Graph Screen, proceed as
