Use to set a differential gap of the Event.
Attribute:
R/W
Digits:
7 digits
Number of data:
2 (Data of each channel)
Data range: 
Deviation, Process, Set value, Deviation action between channels:
0 (0.0, 0.00) to Input span (Unit:

C)
(Varies with the setting of the decimal point position.
However, even if "3: Three decimal places" is set, the maximum
settable decimal places are 2.)

MV: 0.0 to 110.0 %
Factory set value: 
Deviation, Process, Set value, Deviation action between channels:
1.00

MV: 1.0
Related parameters:
Comprehensive event state (P. 9-4), Event state monitor (P. 9-8),
Event set value (P. 9-19), Event type (P. 9-52), Event interlock (P. 9-57),
Event delay timer (P. 9-59), Force ON of Event action (P. 9-61)
Function:
It prevents chattering of event output due to the Measured value (PV) fluctuation
around the event set value.
