Hi all,
I have a Hameg HM 7044 power supply. I also have a lbview program that should control the power supply.
However, The problem is that when I run the program, it gives me no error but any change in voltage or current is not relected on the power supply. I hjave tried with both USB and RS232 connections. It is as if labview program is not having any control on the power supply.
Is there any hardware setting or switch on the power supply that I have to set in a particular way to allow for control through RS232 or USB? I have looked up the manual but could not figure out what to do.
The open vi for HM7044 has choice of connections namely 'COM1', 'COM2'...etc. I have tried all options. It gives connection error only for one of these connections. For all other connections, the labview program gives no error but fails to change anything in the power supply.
Thanks a lot for your inputs
Best,
