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

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

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.
