The TP4000ZC has 14 measurement functions. The measurement functions are explained in this pdf. The 14 functions include an auto test function, a manual test function, a load test function, a voltage measurement function, a voltage load test function, a voltage wiring function, a current measurement function, a current load test function, a current wiring function, a measuring resistance function, an external resistance function, an external resistance manual test function and an external resistance load test function. The load test function is performed by the TP4000ZC. The function automatically preforms an open-circuit test and a short circuit test. The software also has a built in memory function. The memory function remembers the last 10 or 100 measured data. The data can be saved in a file or cleared. The data can also be loaded into the memory function. The software also has a configuration function.
Check out the product manual for the TENMA 72-7745 and the documentation for the PC software. The software is useful, and may answer many of your questions. But the disclaimer is that it is not intended to replace professional meter repair or calibration, which the user is responsible for. I recommend that you purchase a meter that is specified for professional use. This disclaimer is applicable to the software and to the information and opinions in this post. -Davo
The software needs some work to improve the menus and their usability. Also, the software is slow to start up. And, a useful feature is missing - it would be great if the switches were highlightable, since it is often easiest to see which switch is in which slot.
I have been using the Tekpower TENMA 72-7745 with its Tekpower TENPA-10 battery pack for the last year. So, I have been very familiar with this meter and I have worked on it extensively, making modifications to the software and the meter. I have had a close look at the build quality and the software.
It is a well-made meter, which is what you should expect from Tekpower. The backlight is just as bright as advertised. The LCD display is easy to read. It contains a power switch, which is positive. I did not like the software selection menu, which has three pages of choices, but I can live with that.
USB Port: The UNI-T meter has a standard USB port and appears to communicate with a PC in the same way that any other meter would. Most meters communicate with the PC by sending digital data over RS232.
Then I spend some time on evaluating the battery performance before a complete teardown. In the teardown I found that the PCB is actually for a UNI-T UT60E. If you want to know as much as possible about this meter or the UNI-T UT60E for that matter then check out the specifications listed in part 1 and watch both videos. 827ec27edc
