this does not result in a setting error. In such cases, check the upper and lower alarm limits.
(See 5.1.6 Alarm setting for details on alarm settings.)
Range Setting Limits
(1) The relationship between Range 1 value, Range 2 value, lower limit value, and upper limit
value shall be set to satisfy the following equation.
Lower limit range ≤ Range 1< Range 2 ≤ Upper limit range
(2) The maximum number of digits that can be entered in the range is 4. Decide the number
of decimal places considering that the maximum value varies depending on the number of
decimal places.
Example Number of decimal places = 2: Maximum value = 99.99
