Digital Displays Chapter 3 Menu modes 3 17 FILTER JUMP VALUE See the Easy Advanced mode selection page near the beginning of this manual and choose advanced mode The Filter Jump value allows you to decide how the display will respond to a process step change It does this by overriding the filtering if the input signal moves by more than a chosen amount in one conversion The Filter Jump default value is 10 This means that for noise amplitude which has a peak value of less than 10 of the input range filtering will be applied Any signal movement greater than 10 of the input range will cause the display to jump immediately to that value without filtering After that jump normal filtering will be re applied provided signal movement thereafter is less than 10 per conversion Guidance For noisy systems increase the Filter Jump value up to a maximum of 99 Choose a value which gives a good compromise between filtering and response speed For reasonably clean signals a Filter Jump value of around 10 or less will give a good compromise between filtering and response speed to step change inputs Output Al farms OFF LOK Lockout Switch must be OFF Mil Press repeatedly until you see FiL J XX where XX is the Filter Jump percentage Default FiL J 09 You can set from 00 to 99 Use the DIGIT and UP or DOWN button to increase or decrease this value Press repeatedly to accept and return to display 2
