content: I just changed jobs and am starting to work for my self.SCREW THE MAN!I am starting to do some lower power electronics from what I am used to and am looking at buying a higher end handheld multimeter. I would like to know if the the Fluke 289 or for that matter any other high end handheld DMM can measure voltage and current at the same time. I have not gotten my hands on a Fluke 289 to see if this can be done and would like to know if this can be done. If not can someone recommend a meter that could do this?My application is for those interested is to measure the energy consumption of some devices in the field and would like to know the current draw and voltage at the same time. So I need things like logging and connection over bluetooth or WiFi is a big plus.Thanks in advance,Wylie

content: I agree with mtdoc. With the Mooshimeter you get something you can leave to log the data. Actually you can buy 4 for the same price as the Gossen. Now if you want a Gossen, they are one of the top brands and you can't go wrong with them.

content: QuoteOk that is awesome and exactly what I am looking for! The right tool for the job. I cant seem to find the current resolution on ranges lower than 10A. Needs some more investigation.thank you mtdocQuoteI am getting a better multimeter than what I have. I entirely forgot about Gossen when writing this post and I am definitely considering buying one.It is kind of old why more meters would not have this kind of feature. I have a couple of old Fluke 45's that can measure current and voltage at the same time. It is interleaved but still is a very helpful feature when looking at power consumption of a DC load. AC makes things a big more complicated because of the need for phase measurement, but that is not hard when designing a meter. Other than the mechanical switch coupling the inputs, I would think it could be done with software. Maybe I am wrong I have never designed a DMM.

content: Quote from: thewyliestcoyote on May 08, 2015, 05:40:50 amThe main reason I have a Gossen Energy is due to the power and energy measurement. It can measure power from uW to kW for both AC and DC. Another nice detail is a single current connection, there is no need to move the plug when going from uA/mA to A (This has saved me a couple of fuses when I measure standby current and the device suddenly goes out of standby).

content: The fluke 123 and 124 I believe can. They have two DMM and Oscilloscope in one device.But pricey! Not sure how low on the amps. But you can get a shunt adapter to read 4 to 20ma.

content: The METRAHIT ENERGY has an optional external AC adaptor for bench use, a huge advantage over the Fluke.

content: The Gossen plug type changed after 2003. It has now 3 prongs.NA-HIT 2X 140$.Also made my own for the Gossen 30M.

content: Quote from: Wytnucls on May 08, 2015, 03:58:55 pmthere are still both types used, i.e. my Metrahit Energy uses the NA X-TRA (with stereo jack plug type) and my 30M has the connector used with the NA-HIT 2xCan you share some details about your DIY for the 30M?I have tried to find the connector but with no luck far.

content: Couldn't find the right plug either. Just a quick and dirty conversion to a stereo plug. Conversion is reversible with no meter damage.
