This is useful for making settings while checking theoperation status of the K3MA-J.Process MeterK3MA-J5Convenient FunctionsScaling TeachThe parameters (inp.1, inp.2) for the K3MA-J’s initial setting level can be set using actual input values with the teaching function. After displayingthe parameters, the actual input settings can be made with the following operation.Teaching modeUseto shift tothe next parameterwithout registering.“T” flashes.Monitor modeUseto registerand shift to monitormode.Normal change“T” lights toindicate that theparameter isvalid for teaching.“T” turns OFF.Next parameterOUT Types (Comparative Output Models Only)OUT 1 and OUT 2 can be set to operate in one of the three following modes in accordance with the compared values:• Upper limit (High Acting):The output is turned ON when the measurement value is greater than its set value.• Lower limit (Low Acting):The output is turned ON when the measurement value is less than its set value.• Upper and lower limits (Outside Band Acting):An upper limit (H set value) and lower limit (L set value) can be set independently.The output is turned ON when the measurement value is greater than upper-limit set value or less than the lower-limit set value.Upper Limit (High Acting)OUT1/2 valueLower Limit (Low Acting)OUT1/2 upper-limit valueHysteresisMeasurement valueMeasurement valueONOutputHysteresisHysteresisOUT1/2 lower-limit valueONOutputONOFFOFFOFFHysteresisMeasurement valueOUT1/2 valueOutputUpper and Lower Limits(Outside Band Acting)The three types of output operations shown above can be combined as desired.
