Attached Functions
Sensor correction
coefficient
Sets slope of input value from a sensor.
Sensor correction
Corrects the input value from the sensor.
Set value lock
Locks the set values to prevent setting errors.
Auto/Manual control
switching
Switches Auto/Manual control.
In Manual control, sets MV with the or key.
SV ramp function
When the SV is adjusted, it approaches the new SV by the preset
rate-of-change. Set SV rise rate and SV fall rate respectively.
SV Rise/Fall rate start type
When control output is turned from OFF to ON, or switched from Manual
to Automatic control, SV start or PV start can be selected for SV rise rate
or fall rate action.
Program control
1 pattern; 9 steps
Power failure
countermeasure
The setting data is backed up in the non-volatile IC memory.
Self-diagnosis
The CPU is monitored by a watchdog timer, and if an abnormal status
occurs, the controller is switched to warm-up status, turning all outputs
OFF.
Automatic cold junction
temperature compensation
This detects the temperature at the connecting terminal between the
thermocouple and the instrument, and always maintains it at the same
status as if the reference junction location temperature was at 0 (32 ).
