Setting the input compensation function for each section (4 sections)
This compensation function can be used when there is a mechanical
problem such as a heater block, a chamber, etc., and when the present
value(PV) does not match the external measured value due to the
position of the temperature sensor.
⑨ Alarm latch function setting (OFF-AL1-AL2-AL3-ALL)
This function maintains the alarm status until it is manually released
from the outside after an alarm occurs. To disable this feature, press
the Shift ( ) button on the front of the product.

minimum value to identify the problem.

Ex.) The actual temperature of the control object used at
0 ~ 1000 ℃ was measured. Measurements at 250 ° C are
+ 5 ° C, -2 ° C at 500 ° C, and + 7 ° C at 750 ° C,
In this case, the compensation settings are as follows.
FR-L=0℃, BSP1=250℃, BSP2=500℃, BSP3=750℃, FR-H=1000℃
BS0=0℃, BS1=-5℃, BS2=+2℃, BS3=-7℃, BS4=0℃
