When I send the measurement command "MEAS: VOLT?" to DMM6500, after sending the set voltage value command "APPL CH1,(voltage)" to 2230G-30-1, I found that no matter whether the measured value is displayed on the screen, or when the NI-VISA driver "Session.RawIO.ReadString()" is used to read the data, there is always a delay of one step to obtain the accurate value. In other words, the voltage value measured this time is the voltage value output by the power supply in the previous step. Is this normal? Or is there any way to solve this problem?
The delay time I set for each step is 1 second, DMM6500 FW version is 1.0.04b.

Please download and apply firmware update from tek.com site.
If issue persists after FW update, an IOTrace file will be helpful to fully see the sequence of events between the PS and the DMM.
