The K3NX Process Meter displays voltage or current input after performing the
numeric conversion of the input.
The K3NX has the following functions.
Scaling Current or voltage input is converted into a value within a specified range to dis-
play engineering units.
There are two scaling methods: scaling by using measured input values or scal-
ing without connecting a sensor and using assumed input values instead.
Refer to 3-2-4 Scaling Menu.
Comparison output patterns can be selected from the standard, level, or zone
output depending on the application.
Refer to Comparative Output Patterns, page 48.
Refer to Linear Output Range, page 51.
BCD Output A digital data output format where every four binary bits is numerically equivalent
to one decimal digit.
Refer to Section 6 BCD Output.
Refer to the Communications Manual.
HOLD is an external input which is used to stop the A/D process and freeze the
display. The comparative, linear, and BCD outputs are also retained.
Refer to 4-4 External Input Signals for details.
RESET is an external input to reset the present maximum and minimum values.
The process value when the RESET is ON is set as the maximum and minimum
values. The maximum and minimum values can be reset using the front panel
keys.
Refer to 4-3 Displaying and Resetting of Maximum and Minimum Values.
Teaching The K3NX is provided with a teaching function that can set an actual measured
value as a setting value without key input.
This function is useful for setting parameters while checking the operating status
of the K3NX.
The teaching function can be used to set the set and scaling values. It can be
also used to set the linear output range of the K3NX with a Linear Output Board.
Refer to 5-1 Teaching Function for details.
Output Test This function is convenient for checking a system to which the K3NX is con-
nected, especially when some inputs cannot be operated. The K3NX simulates
an input to check the output conditions.
Refer to 5-2 Output Test for details.
Forced-zero By turning the ZERO input ON, the process value can be calibrated to zero.
This function is useful for measurement on the basis of any process value as
zero.
This calibration is maintained without being influenced by input range changes
or power interruptions until the next time the ZERO input signal is turned ON or
the scaling value is changed.
Refer to 4-1 Forced-zero for details.
