what do you meen with "its only USB A to USB C" 1:00 you make it sound like your missing something with "it's only USB A to USB-C" what else had you hoped for.? a secondary cable with TypeC to TypoC, which doesnt make sense as most 5v chargers are still Type-A. I really dont see the point with using a process meter as a very crude DMM for reading voltage or resistance, or current .. Wouldn't you turn to your DMM (std. multimeter) and a tool that is optimised for that, and often comes with better safety, features, accuracy resolution. I notice your videos about these process meter seems to center around, using them to measure things. IMO, its all these specialized features with close to ref-output-signals, that you can mix & match with programs, conversion.. that could be handy and where other std. tools comes short. Its the granularity of the signal manipulation, timebase, programs, conversion on a small handheld unit with close to ref values' that I see value in. and how can the 20 Ohm test value get a passmark with an error of -1.46% . . 17:11
Process meters are optimised for a specific range and are usually more accurate across that range than a standard DMM would be. There will be very few DMMs in the price range of this LB02 that can measure 4 to 20mA with its level of accuracy and resolution. People are free to utilise the meters however they wish, I just do basic videos to determine the measurement accuracy as I don't have the ability to record videos on sites. The accuracy is made up of a 0.025% of reading +0.3 Ohms, therefore the reading fell between the minimum/maximum acceptable tolerance values. It is not unusual for the overall error value to be greater than the specified accuracy % for low values like this because of the additional digits have a greater affect. Thanks for watching and commenting.
@@three-phase562 I have seen precious little comparing of process equipment and your efforts are appreciated!! The ability (and accuracy) of these relatively inexpensive multifunction devices amazes me. As you have stated, you will struggle to find an accurate DMM in the working PROCESS mA & mV & V ranges (possibly a high end bench unit) and you would need a small stable supply in addition. You would need to spend approx 10x the value of the LB02 to achieve this. Temperature would require a decent decade box (RTD's) plus the power supply as mentioned. Makes the LB02 look like seriously good value. Also I would like to add that the LB02A offers a full colour LCD display plus extra temperature functions. Does the LB02 allow you to set the internal cold junction temperature (like LB02A) to zero?
@@scottshaw1310 I appreciate you putting me on to this LB02 unit. It is quite an eye opener what capability I am seeing with these units for the price they are being offered at. I am only really seeing the LB02 on Amazon UK. There are a few for the LB02A but they don't seem to match the specification on the Brightwin website. Yes you can manually set the cold junction temperature when you are in TC / RTD mode. The manually entered value gets reset to the ambient temperature when the units is powered down and back on again, so has to be set again. Thanks for watching and commenting.
Nice work that adds the details to LB02 performance.
