Data Grid on DAQ Bench Vue displays values in scientific notation. Can this be changed?
Not sure what you mean. Data is shown in uV, mV, V, etc. Not in x.xx x 10^y. This format can't be changed.
I would have to disagree with you. I have multiple channels that display calculated data from my measurement channels the as an example calculation is (ChA - ChB)/(ChA + ChB). As you can see the result of this calculation is unit less. The range of the result is also always between ±1.000. Because of this format we actually lose a digit of resolution when the gain goes negative.
Up until now we have used BenchLink. We did not have any trouble viewing these values on the monitor they were displayed xxx.x m or -xxx.x m not as shown in the BenchVue Data Grid screen grab above.
When we export the data it is fine.
Perhaps you have set your Windows preferences to show scientific notation. Or you have an older version of the DAQ app. Here is a screen grab from the most recent release of the DAQ app:
I have the latest version of the DAQ app.
As I said the channels being monitored are calculated channels not mesurement channels.
Give this a try:
Set up a calculated channel that subtracts 102 from 101. Call it A (102 - 102) Vdc
Set up a 2nd calculated channel that adds 102 to 101. Call it B. (101 + 102) Vdc
Set up a 3rd channel that divides A by B (A/B) no units.
Now put the 3rd calculated channel in the data grid.
What do you see?
OK, now I see. You're right, computed channels are displayed with scientific notation. I think that's probably because we have no way of knowing what kind of math you will be doing, so the result could be very small or very big. And as you noted, there is no way to change this.
There are WIndows localization settings that can affect numbers. That's what I was referring to. But it clearly does not apply here.
We were using Benchlink prior to getting this latest version of BenchVue. Benchlink did not have the data grid tool, it just displayed the current values of all channels next to the channel in the channel configuration table (BenchVue does not do this either). The values for the calculated channels displayed there were not in scientific notation. Why the change? We use these current values to determine if we are going to allow these long term tests that we are running to continue. We may just have to go back to BenchVue.
I have passed your concern on to the developer of the app and the rest of the BV team. We have made a lot of changes to the DAQ App so that it can eventually replace BLDL 3 (basic and Pro), and I see no reason why we can't offer some way to format this data. Thanks for pointing this out.
Thank you Brian! I appreciate the exchange.
