K-50

Temperature Meter 

K3MA-L

Temperature Input Shift

Input shift equivalent to the setting value supported for all points within 
the sensor measurement range.

Parameter Initialization

This function returns all of the parameters to their initial values.

Use this to reset the K3MA-L after returning it to its factory-set condi-
tion.

Average Processing

Average processing stabilizes displayed values to minimize flicker by
averaging the fluctuating input signals. Average processing can be
performed for the measurement values in either of four steps (OFF, 2
times, 4 times, or 8 times).

This is useful for ignoring rapid fluctuations, e.g., eliminating spike
noise.

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.

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.
