Setup Items
Assigning Computation Channels
• First-CH/Last-CH
You can assign channel numbers [31] to [60] as computation channels. The range of
numbers here is used to set the range of channels for setting the computation
function.
• Math Off/On
Turn ON/OFF the computation function for the computation channels specified by
First-CH and Last-CH.
