Hello there.
I have a OMEGA FPR 303 Flux meter which counts pulses. I conect it to a agilent 34972A using a 34901A board. I know that the pulses are at a 10V range and i use the frequency measument. When i configure the agilent using its front panel i manage to receive a right response, zero when the flux meter is still and some value when there is some flow.
Although I can configure using its front panel I can not configure using labview.
I tried several different programs but until now i wasn't able do this (yes, I am trying to solve this for 3 weeks already).
I can configure temperature, voltage, and even switching (using a 34903A board in the latter). But something happen when i try to send the configuration for frequency measurement to the datalogger.
In the end i only receive background noise, which is the response for 100mV range (which is the auto configuration).
What i Ask here is: How can I use labview to get Frequency measuments using 34972A along with a 34901A board?
Here is the program I am using right now.

LIke anything else with an HP/Agilent/Keysight 34970/34972.
You diagram only covers step 1
You need to pass your stan list to these two VI's (Even if your scan list is just ONE channel)
Then scan in instrument...

Here is a better picture of steps 1 and 2 but I am configuring for voltage, current (scaled shunt) and temperature, then setting up my scan list.

oK, I will try this and report back!
Thank you so much.

Hello again,
This is what i did, trying to follow your advice.
I managed to obtain a good measurement with right range. When I try to run it for a longer period, however, I keep on receiving this error that i do not know whats the cause.
I would really appreciate if someone gave me a help on solving this

First off the sequences are NOT needed, use the Error Cluster for flow control.
You should pause for a moment and have a look at some basic LabVIEW tutorials http://www.ni.com/getting-started/labview-basics/environment
As for the error I don't think you need to set a scan interval, or just set it to 0.00.
I have attached my 34970 scan VI you can use. It's basically the example from the Agilent VI's with a few modifications to make it more usable.
