Setting example
■Example 1
This example assumes that the thermocouple input module is used with the following settings for the channel where a K
thermocouple (-270 to 1370) is connected.
• "Scaling enable/disable setting": "Enable"
• "Scaling range upper limit value": 5000
• "Scaling range lower limit value": -1000
• "Scaling width upper limit value": 100
• "Scaling width lower limit value": 0
A measured temperature value and scaling value become as follows.
