1: Change of digital output values under the following conditions
Ex.
• Input range: 0 to 100AAC
• Sampling cycle: 10ms/8CH
• Time constant setting: 1000ms (1s)
• CT input value: changed from 0A to 100A
When 1000ms passes after the CT input value reaches 100A, the digital output value with a primary delay filter
reaches 63.2% of the digital output value in the sampling process.

Ex.
conditions
• Time constant setting: 2000ms (2s)
• Time constant setting: 1000ms (1s)
• Moving average processing: 16 times
