I am tring to control a power supply (from Kikusui), using the Kikusui device, USB-TP PIA4850. I use the library, Ivi.Visa.Interop. Following is the code where I am succesfully able to control the power supply, by setting the desired voltage.

(Link to programming guide: https://www.kikusui.co.jp/kiku_manuals/P/PIA4800/english/index.html)

(Link to operation manual: https://www.kikusui.co.jp/kiku_manuals/P/PIA4850_E5.pdf)

Using Ivi.Visa.Interop;
namespace USBTPTest

class USBTPController


private IResourceManager3 rm = new ResourceManager();
private IMessage iMessage;

public USBTPController() //to get the address of the device connected and open the address if found
 
 string[] adrsList = rm.FindRsrc("?*");
 if (adrsList.Count() != 0)
 
 Open(adrsList[0]);
 
 

public bool Open(string str)
 
 string addr = str;
 iMessage = (IMessage)rm.Open(addr, AccessMode.NO_LOCK, 0, "");

 //iMessage.WriteString("TRM 2");
 iMessage.WriteString("NODE 5");
 iMessage.WriteString("CH 1");
 iMessage.WriteString("REM 1");
 bOpened = true;
 return true;
 

public bool SetVoltage(float vol) //method to set the desired voltage to the power supply, when called with an appropriate argument

The set voltage is checked by a multimeter on the power supply terminals. Similarly current is also set and checked. Until here the code runs and gives the expected results.

public string ReadVOut()
 
 iMessage.WriteString("VOUT?"); //Query OUT(ON/OFF) measurement value
 string VOutStatus;
 VOutStatus = iMessage.ReadString(1024); //Read from PIA
 return VOutStatus;
 
public string ReadIOut()
 

 iMessage.WriteString("IOUT?"); //Query OUT(ON/OFF) measurement value
 string COutStatus;
 COutStatus = iMessage.ReadString(1024); //Read from PIA
 return COutStatus;

 

The problem occurs when I read the voltage/current values being outputted. Although I am able to read the values correctly, sometimes reading Voltage using ReadVOut() gives current and vice versa. I am not able to figure out if its a fault in the code or in the power supply I am connected to, or something else. And kind of help/ideas/leads would be much appreciated.
