Current Measurement AC/DC
Current Measurement AC/DC
Looked at the CM3 DataLogger but it looked like it was AC only. Found the current probes, such as TA167 that will do both AC&DC but not sure which data logger to match to.

Hi chazsolar,
The answer to your question completely depends upon what it is that you are trying to achieve. So could you explain, in detail what you want do with the device?

Re: Current Measurement AC/DC
Measure DC current upto essentially 50Amps for a Hydrogen ingestion unit for data logging changes in current consumption. Later, the set-up could be used to measure AC on motor circuits all under 200Amps. The probes that can readily measure AC or DC are pretty clear but the collector side is not.

Hi chazsolar,
OK, How many channels of data would you be expecting to log at once, and how detailed do you need the measurements to be (to how many decimal places)?

Re: Current Measurement AC/DC
One decimal place and up to three channels maximum. This would allow me to measure the DC channel or an AC 3phase motor (Phase A,B,C) current. For these projects that is all I really need.

Hi chazsolar,
O.K., up to 1 decimal place of 200 is a full-scale range of 11-bits, so you would need a 12-bit PicoScope. That leaves you two choices, depending upon whether or not you will also be measuring potentially hazardous voltages.
If the answer is that you're not, then a PicoScope 4244 should be all you need (see here: https://www.picotech.com/oscilloscope/4 ... 4-overview). If you are going to measure anything resembling the mains voltage at a wall outlet then you would be better off using a PicoScope 4444 (see here: https://www.picotech.com/oscilloscope/4 ... ifications), which has cost-effective differential probes for 1000V (pk) voltage, CAT III measurements (see here: https://www.picotech.com/accessories/d9 ... tial-probe).
