2380 Current Monitoring

Post by alanhawse » February 2nd, 2020, 7:16 am

On the back of the 2380 there is a terminal labeled "I Monitor".

I have two questions
#1 The relevant sections says:

"Current monitoring (I Monitor)
An external voltmeter or oscilloscope can be connected to the load through this terminal to display input current change. You can calculate the current value with the voltage value."

Presumably this means that the voltage value is proportional to the current... but I suppose it would have been nice to have documented that a bit more clearly... My question is what is the VI relationship for that terminal?

#2 Do you have a recommendation for a cable to attach to that BNC connector? I am assuming that probably was mainly meant to attach to an oscilloscope?

Thanks for bringing this to our attention.

The I monitor signal provides a 0-10V output proportional to the 0 to Full Scale of the current range in use.
Depending on which specific model you have, the ranges will be different.
For example, 2380-120-60 has both 6Amp and 60Amp range.

As for BNC cable to attach to it, most any with 50 ohm characteristic impedance will be fine.
With Tek AFG, we supply 3ft shield BNC cable using part number 012173200.
