  8. SETTING AND KEY OPERATION 8.1 Limiting the Setting Range of Set Value (SV) To limit the setting range of the Set value (SV), Setting limiter is used.  Description of function Setting limiter is a function to limit the setting range of the Set value (SV) within the input range. Example: The input range is from 200 to 1372 C, the Setting limiter high is 400 C, and the Setting limiter low is 0 C.

• Page 113
  8. SETTING AND KEY OPERATION Setting limitter high is initialized to the input range high value when the input range is changed. Similarly when setting limiter low is changed, it is initialized to the value of Input range low. [Example] Assuming that the setting limiter high is set to 200 ºC and the setting limiter low is set to 50 ºC on the instrument with a range of 0 to 400 ºC, changing the input range high to 300 ºC will initialize the setting limiter high to the value same as the input range high (300 ºC).
