Dynasonics D601 Series Doppler Ultrasonic Flow Meter - Manual (Page 21)

Rev. 4/00 -3.8- D601
After a successful flow meter installation and startup
(covered in the previous sections of this manual) the D601
can be keypad configured to provide select engineering
unit readings of flow and a scaled 4-20mA output.
Configuration inputs are made via the keypad and are
stored by the microprocessor. The entries are retained by
the flow meter’s E
2
PROM memory in the event of power
failure. If fluid velocity readings, FPS or MPS, are the
only required measurement keypad configuration is not
required.
UP/DOWN Arrows
Allow changing of the D601 configuration constants. Use
the UP arrow to increase constant values and the DOWN
arrow to decrease values. The arrows can be
momentarily pressed to change values incrementally or
held to advance continuously. Constants outside of the
valid range of the D601 cannot be displayed. The
scrolling rate at which the values will change is two tiered.
Scrolling will be relatively slow during the first five seconds
of a continuous keypad press; the scrolling rate will
increase after that time to allow rapid changes of large
values.
