The PicoLog CM3 Current Data Logger is a compact, easy-to-use data logger for measuring the current consumption of buildings and machinery.
CM3 data logger - highly impressed and great value for money.
I have been using a CM3 to monitor a heavily loaded 63 amp 3 phase power supply for a music/dance/steam/beer festival.
The CM3 has been great. We got into a current imbalance situation, and with the PicoLog software set to give a 30 minute scrolling history, we could see how we needed to move things around to correctly re-balance things.
The CM3 is exceptional value for money. Neither the CM3 nor the software is perfect, but it’s a thirtieth of the price of my idea of excellent but still not perfect.
I also have a decent data set to say that we need to consider how we use that 63 amp three phase supply at prime event time, as it no longer seems up to the job.
