Features
The K3NH Temperature Meter displays temperature input.
The K3NH has the following functions.
Refer to page 31. Sensor voltage or current output is converted into a value with-
in a specified range.
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 53.
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 K3NH 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 4-3 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 4-2 Displaying and Resetting of Maximum and Minimum Values.
Teaching
The K3NH 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 K3NH.
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 K3NH 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 K3NH is con-
nected, especially when some inputs cannot be operated. The K3NH simulates
an input to check the output conditions.
Refer to 5-2 Output Test for details.
Standby Sequence
When the K3NH is tuned on, the K3NH will have no output until the measured
value is within the PASS range. This function avoids unnecessary output until
the output is within the measurement range after the power is turned ON.
Hysteresis
The established setting value includes a hysteresis setting to prevent “chatter-
ing” of the output when the measured value fluctuates in the vicinity of the setting
values.
Hysteresis is enabled when the measured value is starts to become smaller than
the HH and H setting values and larger than the LL and L setting values.
Refer to Hysteresis, page 46.
Remote/Local Selection
The K3NH can be operated remotely through a host computer or locally with key
inputs.
Remote Mode: For programming remotely by downloading setup parameters
from a host computer via RS-232C.
Local Mode:
Programming is performed with the front panel key input.
