Dear all,
I have faced some issues when trying to read DC voltage values from a hp 3478a multimeter. The Labview version I have is 2022 Q3. The connection between instrument and PC is via a GPIB/USB interface: 82357A. In the attached figure1, the NI instrument driver finder detects all other instrument connected to my PC except the 3478a multimeter. The multimeter shows up with the category of other manufacturers and with a number which is physically shown on my multimeter. I believe the multimeter is connected to my PC since it returns this value. However, in my .vi file, I want to read the DC voltages from the multimeter but the front screen shows 0 (.vi picture shown in Figure 2, the DMM icon box is from the instrument driver downloaded from NI website). Can anyone help on resolving this issue? Any suggestions would be greatly appreciated.
