Logging a voltage and a current in the same time
AlexResch:
I would like to log a voltage ( 6.3V ) and a current ( 150mA) in the same time and then use the table to build a graph. Is there a multimeter which can do that at some chosen frequency ( aprox 3-5 times/second ).

The Mooshimeter might be a good option for you. They are quite handy.
RoGeorge:
Metrix MTX3283 DMM can log V and I in the same time (3 wires only), fastest sample rate is 1 measurement/second, and the maximum length is about 3000 measurements. The log is kept inside the DMM, so it can log without a PC.
joeqsmith:
Five samples/second with V/I may be an expensive meter. You may be better off with a cheap microcontroller evaluation board with a decent ADC.
There is always the Analog Devices, or in my case I have a Labjack.
