How to detect the Current Probe Programatically through labview in pico 3000 series scope

Post by RBEI » Fri Aug 23, 2019 6:35 am

Hello.

I am using Pico 3000 Series scope and trying to control it programmatically through LabVIEW using the DLL provided from Pico Tech.

I am able to read voltage programmatically through LabVIEW, but not able to read current programmatically through LabVIEW using the current probes provided from the Pico Tech.

Can anyone help :D

Hi,

The BNC probe interface on all the 3000 series scopes are completely passive. There is no way to detect the probe connect.
So using a current clamp or sensor, the scaling will have to be coded yourself. This scaling could fixed or controlled via front panel button etc. Especially if you have a current clamp that has two ranges.

For example our TA018 has two ranges-
1 mV/10 mA
and
1 mV/100 mA
So 1 mV/10 mA range you need multiple the channel voltage by 10 and
1 mV/100 mA range multiple the channel voltage by 100.
