parameter, and
related with them minimum durations of logical states
“PULSen”
- input divider, can be set in range 1 to 19 999. This parameter defines the
number of pulses per single revolution .
Value 0 is interpreted by firmware as
1
pulse/rev.
This parameter must be set correctly to let device works properly.
“PrEc”
-
precision of result displaying. There are available settings from
“0”
(precision of 1
unit) to
“0.00000”
(precision with 5 digits after decimal point)
“unit”
- The unit of rotational speed used for recalculation of current measurement can be
set to:
“SEC”
- result expressed in revolutions / second
“min”
- result expressed in revolutions / minute
“hour”
- result expressed in revolutions / hour
“F or P”
- kind of value shown on the display:
“Freq”
- frequency (rotational speed),
“PEriod”
- period (time per one revolution).
