Memory Function and Real-Time Saving Function
File size (bytes) = header size
*1
+ data size
*2
*1. Header size = 190 + 27 × saved analog channels + 64 × saved logic channels
*2. Data size = (20 + 16 × saved analog channels + 9 × saved logic channels) × (Recording Length (div) × 100 + 1)
(Saved logic channels = 0: none saved / 4: saved)
Recorder Function
File size (bytes) = header size

*1. Header size = 190 + 27 × saved analog channels + 64 × saved logic channels
*2. Data size = (20 +32 × saved analog channels +18 × saved logic channels) × (Recording Length (div) × 100 + 1)
(Saved logic channels = 0: none saved / 4: saved)
