Good morning.
My company recently purchased a NI-4065 DMM USB and I am in the process of writing my own application in C++ Builder 6.0 to interface with it.
The purpose of the application is to do all ranges of measurements for DC Voltage, DC Current, AC Voltage, AC Current and 2-Wire Resistance. I have the application working properly and interfacing with the hardware properly. My DC readings and Resistance readings are very quick to update, but my problem with which I need assistance is the AC measurements. Although the measurement itsself is correct, it takes extremely long to read a value (2-3 seconds) no matter the resolution, min frequency, max frequency or power line parameters I set it up with.
I am using "niDMM_ConfigureMeasurementDigits" and "niDMM_ConfigureACBandwidth" to set up the session for AC measurement, and using "niDMM_Read" for reading the measurement value. I use this same read function to read my DC measurements and resistance and they execute very quickly.
Am I missing the initialization of some crucial properties for AC measurements to enable it to read quickly, or am I doing something completely wrong? I would like to have at least 1 reading per second but prefer more with less than 6.5 digits. I am also experiencing a huge time delay when switching measurement modes and sessions get closed and created again.
Please assist me with this problem if possible, as it is crucial to have a good measurement update rate.
Thank you.
