Review on 🔧 Revolutionize Your Toolbox with the PrvnPro Handheld Digital Backlit Multimeter Tool by Michael Hudson

I was very interested in the data collection capabilities of the USB port and the PC software. Since I didn't see a review on this feature, I decided to explore it myself. The first thing I did was see how "off" the measurement was compared to my BK 390 and Fluke 77. I measured the voltage of a 9 volt battery. This EM6180 fluctuated between 9.43 and 9.44 volts. The BK 390 was stable at 9.43 volts while the Fluke 77 fluctuated between 9.44 and sometimes 9.45 volts. My BC was calibrated a few years ago and has an accuracy of +/-(0.1% + 2) on this measurement. The actual measuring voltage of the BK 390 of 9.43 volts is therefore within the permissible range of 9.44 to 9.42 volts. This EM6180 has an accuracy of +/- (0.8% + 5) on this measurement. The actual voltage from the 9.43 volt measurement obtained with the EM6180 is within the acceptable range of 9.56 and 9.30 volts. Although the EM6180 has a wider tolerance range, its measurements are within a tighter tolerance range than the BK 390. That's not too bad, but the tolerances can be greatly improved with modern electronics, especially for a meter of this price. PrvnPro EM6180 has a USB data port. I was interested in data logging capabilities to measure various charge and discharge characteristics of batteries. What I needed was the ability to take a "snapshot" of temperature, voltage or current at an interval of at least 1 reading per minute. The bonus is that the data is also available in a file that can be exported to spreadsheets and charting programs. This meter comes with a blank label CD containing the software. This is VERY basic software as it doesn't do anything fancy, but it allows me to take measurements at intervals of up to seconds and save the data as different file types including Excel file type. very good! I tested the multimeter in USB mode to see if the multimeter would switch to USB power instead of using its 9 volt battery. I disconnected the 9V battery while the EM6180 powered my laptop and took "snapshots" of voltage readings at 5 second intervals. When I disconnected the 9 volt battery the meter died meaning the meter always uses its 9 volt battery. As long as this meter is in USB mode, it will never turn off automatically, which is ideal when you're logging data for long periods of time. Meter. Two improvements would be using the PC's USB power supply when the meter is connected to save the 9V battery and the other would be tighter circuit tolerances.
