17 Parameter Transfer
There are two parameter operations: Individual Parameter Transfer and Individual Parameter Request.
A single session is concluded only when this Instrument returns an IPS (Individual Parameter Send) in response to an IPR (Individual Parameter Request) from an external device, or when an external device or this Instrument spontaneously sends an IPS. If this Instrument received an IPS, the value of the applicable parameter is changed.
Depending on the function of a parameter, Individual Parameter Send may be used to issue a command to the Instrument or Individual Parameter Request may be used to check Instrument status information.
