(OP)
I have to go to India soon and measure a 4kw motor current in relation to speed that is used to start a big mining mill.
So i'm looking to produce a graph of rms current vs motor speed ( and time )
What would you recommend i take.?
Handheld current clamp / data logging software / multimeter etc etc
Please be model specific
I've been looking at there seems a hundred ways to go.
Anyone here done this thing before ?

I recommend a digital scope instead of a logging multimeter. You might have some transients that the meter will miss. The old scopes store data on floppy disks, the new ones on memory sticks, so logging is no issue. A two channel scope may also allow you to capture current and speed vs time, and then you can post process that data to get the current vs speed relationship.

Also, going to India for a 4 kW motor seems a bit OTT.

If it is inded 4MW, the test equipment becomes a quantum leap different, because it is likely to be Medium Voltage.
