This is useful, for example, when measuring the maximum value. Use this to reset the K3MA-L after returning it to its factory-set condition. ## **Average Processing** ~~a~~ **==> picture [107 x 132] intentionally omitted <==** **----- Start of picture text -----**<br> Current value<br>MAX/MIN<br>SHIFT UP “=<br>MAX value<br>MAX/MIN<br>SHIFT UP<br>MIN value<br>) ) =<br>Ee»<br>MAX/MIN<br>**----- End of picture text -----**<br> 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 chattering in the output when the measurement value fluctuates finely near the OUT value. **Upper limit (high acting)** **==> picture [129 x 82] intentionally omitted <==** **----- Start of picture text -----**<br> Set value<br>Hysteresis<br>Measurement value<br>ON<br>Output F<br>OFF<br>**----- End of picture text -----**<br> **6** **K3MA-L** ## **Nomenclature** |**K3MA-L**<br>**Nomenclature**|**K3MA-L**<br>**Nomenclature**|**K3MA-L**<br>**Nomenclature**|**K3MA-L**<br>**Nomenclature**| |---|---|---|---| |**1**<br>Max<br>Min<br>**SV**<br>**MAX/MIN**<br>**LEVEL**<br>**MODE**<br>**SHIFT**<br>**UP**<br>2.
