8 Frequency/Rate Meter K3MA-F
Average Processing
Average processing stabilizes the display by minimizing any pulsat-
ing or flicker caused by fluctuations in the pulse width of sensor input
or by eccentricity in rotating shafts.
Hysteresis (Comparative Output
Models Only)
The hysteresis of comparative outputs can be set to prevent chatter-
ing in the output when the measurement value fluctuates finely near
the OUT value.
Auto-zero Time
This function sets the time for the display to return to zero when input
pulses stop. Set the time longer than the expected input pulse cycle
(the interval between one input pulse and the next). Proper measure-
ment is not possible if the time is set shorter than the input pulse
cycle.
Startup Compensation Time
The startup compensation time cancels measurement for a predeter-
mined time when turning power ON, to prevent unwanted output due
to temporary input fluctuations.
Changing the Display Color
The color of the value displayed can be set to either red or green. For
comparative output models, the display color can be set to change
from green to red, or from red to green, according to the status of the
comparison criterion.
Display Auto-return Time
This function automatically returns the display to the operation level’s
current value if no keys are pressed for a preset time (called the dis-
play auto-return time).
Move-to-Protect-Level Time
The time required to shift to the protect level can be set as desired.
MAX/MIN Display
The maximum and minimum measurement (display) values from the
time the power is turned ON until the current time can be stored and
displayed. This is useful, for example, when measuring the maximum
value.
