Explanation of Functions Zero-limit If the input value is less than the set value, the measurement value becomes "0. " This function is effective to eliminate display drift and displacement near "0. " L1 z-lim (Z-LIM) Set the following parameter for zero-limit. The zero-limit value can be set only when zero-limit has been enabled. Parameter Zero-limit z-lim Zero-limit value lim-p Set value on/off 0 to 99 Meaning of set value on: Enabled off: Disabled 0 to 99 * L1 lim-p (LIM-P) * The decimal point depends on the "decimal point position" setting. Parameter Setting Procedure A Press the L [LEVEL] Key for at least 3 s in RUN level to move to the initial setting level. · "L 0" is displayed on the level/bank display to indicate the initial setting level. B Press the L [LEVEL] Key again once (less than 1 s) to move to the input adjustment level. · "L 1" is displayed on the level/bank display. C Press the M [MODE] Key several times to switch the PV display to "z-lim. " L 3 s min. L 0 Displays "L 0. " Functions and Operations L Less than 1 s L 1 tmg-h nomal Displays "L 1. " M S L 1 z-lim off D Press the S [SHIFT] Key to make the SV display flash. · The setting can be changed when the SV display starts to flash. E Use the U [UP] Key to change the set value to "on. " · Change the set value to "off" to disable the setting. F Press the M [MODE] Key to switch to the next parameter "lim-p. " · The set value is registered.

Explanation of Functions Average processing There are two types of averaging: "simple" and "moving. " Select one type. The number of samples ("averaging times") can also be specified for the input values to be averaged. Simple average is used when the display refresh period is to be lengthened. Moving average is used to remove periodic noise superimposed on input signals. [. . . ] The setting to be changed will flash. To next parameter. Appendices A-25 Appendices Sampling and Comparative Output Response Times The K3HB-S sampling and comparative output response times depend on the calculations, timing hold type, and, for simple averaging, the averaging times. Refer to the following description for details. Output Refresh Period The K3HB-S repeats input reads, calculation, and judgement output processing. The output refresh period differs depending on whether there are one or two inputs, as outlined below. One input 0. 5 ms Input Input A or Input B Output Input read Output refresh Output Output Output Output 0. 5 ms Input 0. 5 ms Input Input Input Input Every 0. 5 ms Every 0. 5 ms Two inputs 0. 5 ms Input Input A Input B Output Input read Output Output Output Output Output 0. 5 ms Input 0. 5 ms Input Input Input Input Input Input A: every 1 ms Input B: every 1 ms Output refresh Every 0. 5 ms Appendices A-26 Sampling and Comparative Output Response Times Output Response Time The comparative output response time is the sum of the data processing time and the output (relay or transistor) response time. One input 0. 5 ms 0. 5 ms 0. 5 ms Data processing time R R R R Output response time (See note 1. ) Two inputs 0. 5 ms 0. 5 ms 0. 5 ms 0. 5 ms Data processing time R R R R R Output response time (See note 1. ) (Note 1. ) For transistor outputs For one input: OFF ON 1 ms and ON OFF 1. 5 ms For two inputs: OFF ON 2 ms and ON OFF 2. 5 ms For relay outputs The relay operation time of 10 ms is added to the transistor output response times.
