content: Good morning. We're in need of several portable multimeters with the following capabilities:Will see DC use onlyMax/Min and AVERAGEmA and uA measuringExternal datalogging (ideally without too much expense)We have a single Fluke 289 now which is good but too expensive to be buying in multiples and the additional expense for data logging is high.Have many many Uni-T UT61C meters that have served us well but are lacking the AVERAGE feature which is a big deal for our use.

content: Since you log the readings can you use some software like Excel to calculate the average?

content: Quote from: mwb1100 on April 06, 2023, 06:24:48 amMany thanks for the recommendation. Unfortunately the Uni-T and EEVBlog recs don't seem to have the average function. The Brymen's do so I'll likely go this direction.

content: Quote from: Sierra on April 07, 2023, 01:36:54 pmI should make clear that I don't own any of these meters, so I'd call it more "a list of meters to look into" than a recommendation. And according to the manuals, the Uni-T and GW121 do support the avg functionality:

content: Have now ordered Brymen BM827s, UT-71A, UT181 and unfortunately none of them will work. The Brymen won't allow muting at the same time as logging and several other quirks.The UT-71As seemed to be the ticket but DESPITE what is written in the manual do not provide an Average value.The UT-171 would be an option however it uses a rechargeable battery which in the UT-181 did not provide sufficient runtimes. The 171A would be an option however they're no longer available and who's to say they actually include the AVG function.Any other recommendations for a meter that providesmA and uAmax / min and AVERAGEinexpensive datalogging via TestControllerUser replaceable batteriesMost of the time these will be used in the field where the Average function is critical and data logging will not be possible.Now have nearly a day into reviewing meter data sheets and unfortunately after 3x models still can't find something that hits these really, fairly basic, requirements.

content: Try the 121GW and log via phone/tablet/laptop? (No Test Controller support unfortunately.) One quirk is that it only logs what is on the screen. If you're logging and select the Min/Max/Avg function and select Avg for example, it will only log to the app the average being displayed. And, of course you can't download what is logged to the SD card without taking it apart. But you can use the menu system to turn off beep and auto power off and it will retain those settings.Also, look for used F287/F289, especially the F287 as it is typically cheapest.

content: Quote from: Sierra on April 05, 2023, 12:48:26 pmStick with the 289 you already have. You can log and view/share the Fluke forms between staff. Also, servicing and know-how, calibration will be streamlined.Stick with the same vendor. I have 289 and used it for logging, it is great, allows you to create your own reports, exportto Excel or whatever other data processing you want to use.Don't reinvent the wheel. Stick with what works well.If I was running a business, and had engineers designing/testing, I would want them to use the same brand of equipment.289 is kinda bulky, but it works well.Either go with Brymen or stick with Fluke.PS. Anyone can calibrate all your Flukes, not so sure about the Chinese brands.
