I would hope not the later, as this would mean the integral function is dependent on the software loop time, and has much lesser resolution than if it uses all the data. This should be no problem as I can get up to 5V. Target-scoped FIFO in case structure won’t excecute. The system cannot find the file specified. When I run the vi with the highlight bulb on, I can see both x and y data points are going into the xy graph for each change of x input. Then I interpolated the missing rest and came up with “Gauss3” — the orange curve. I of course ran into trouble with the very first VI that I am trying to upgrade.

This ensures the quality and reliability of the and provides protection to units under test. Ive attached both the main VI file and cgroma test VI that contains the password prompt Thanks in advance and sorry for the terribly long post.

Low voltage operation is possible towards zero volts with corresponding reduced current levels see de-rating curves. The number of ticks is determined via the built-in DSP 32bit-counter.

Any help would be much appreciated! I have an energy meter with pulse output. As show, the Vpeak value is significantly reduced and incorrect when using non-synchronous loading. The user can perform online voltage measurements and adjustments or simulate short circuit tests using the simple keypad on the front panel.

Part of this project involves a couple of motion sensorswhich trigger a buzzerledetc. Most of my work is with express VIhowever. The model mainframe holds five load modules to offer up to 10 W load input channels with standard choma inputs.

Hello everyoneThis is my first post here so please bear with me. Now here is the tricky part. The following are the specifications of setting parameters: Each load module contains 3 load current ranges lagview a minimum full current operating voltage of 0.

The maximum power for a single mainframe is 2kW when five load modules are paralleled. Does integral function sum all data in the buffer, or just the last point? Real time measurement of voltage and current are integrated into each load module using a bit measurement circuit with three current ranges. Not sure how to do it.

I want to keep the terminals on this VI the same if possible. I would hope not the later, as this would mean the integral function is dependent on the 6360 loop time, and has much lesser resolution than if it uses all the data. The dynamic loading mode can dhroma different loading conditions for most test requirements.


I’m designing my graduation project using labview. All the indicators were added for debugging purposes.

I am looking for any help and or advice. The Chroma electronic load mainframe accepts the user-installable series load modules for easy system configuration.

The ‘s lanview of the art design uses DSP technology to simulate non-linear loads using a unique CZ operation mode allowing realistic loading behavior. Contact us about this article.

But inspite of that no change of x value is visible is visible on xy graph. I have replaced a new ethernet card but the problem is still there. The installer doesn’t include any additional NI package, nor runtime engine. I also attached the front panel screen shot to have a view how the xy hraph appears during the measurement.

Figure 3 shows the parallel synchronous dynamic loading and Figure 4 shows the parallel non-synchronous dynamic loading of previous designs. I have created a VI that distinguishes difference between 2 images.

The right figure shows the programmable parameters which can be set within the loads: I need a minimum of 3 volts from my daq to control.
