That is mean!   

Somehow it would be interesting to me, what the connected DMM shows...

Another Ebay low cost ex-mod purchase to add to the collection;  not too much to say other the unit looks good inside, no sign of any previous battery leaks.  Very nice item, I look forward to playing around with it on the bench.

General Discussion / Re: How to choose a suitable power inverter?

Check the output voltage and power, make sure the power inverter’s power is not lower than your appliance, and the output voltage is consistent with your appliance. If your appliance is inductive load current, please choose pure sine wave inverter.

Dear "nhantruong123".

Sorry, but I am pretty sure: The user "AutoElecHack" has chosen and bought a DMM already five years ago...

I think the Fluke 87V might be a good choice, I appreciate it more than the rest of Fluke products. Possesses accurate measurement capability by true True-RMS multi-line non-linear current values. Measure AC / DC voltage up to 1000V; measuring the current of 10 A, 20 A in a maximum of 30 seconds, Measuring the frequency range of 200 kHz and% of operation cycle (duty cycle), measuring resistance with a measuring range of 50MΩ / 0.1 MΩ; measuring capacitance of 10,000µF accuracy ± (1% +2); Measure the rated temperature -200,0 ° C to 1090 ° C; measuring current intensity of measuring range 6000A / 0.001A; 20 A overload for a maximum of 30 seconds. The device also supports an input alert function (Input Alert) that gives you an audible warning when using the wrong probe position, ensuring the highest safety for users. Built-in temperature measurement with built-in probe. Designed to meet EN 61010-1 to CAT III 1000V, CAT IV 600V & Electrical safety certification of UL, CSA, TÜV, VDE. Choosing the Fluke 87V is a good choice, see more about this product here: https://techmaster.com.vn/dong-ho-van-nang-fluke-87v.

I think your device is having problems. You should check it out.

I have used and evaluated the [url]Fluke 115[ https://techmaster.com.vn/dong-ho-van-nang-fluke-115-true-rms/url] as a multifunctional power meter, providing users with many applications for checking electrical equipment and electrical systems. The device is equipped with True RMS, which effectively measures many different lines in the circuit. AC / DC voltage measurement with 600.0 mV rating; measuring 600 Ohm circuit, automatic alarm <20 Ohm, switching off> 25 Ohm, breaking open circuit or short circuit of 500µS or longer; resistance measurement with a range of 40,00 Mohm / 0.01 Mohm; measuring capacitance> 1000 µF, accuracy of 5% + 20%; Measuring range frequency 50kHz / 0.01 kHz. Model 115 measures the main circuits with 600V power measurement. The appropriate voltage level measures a 3-phase power distribution system, withstands continuous overpressure that can occur on the grid or in industrial environments. The device meets all electrical safety standards CAT III 600V, IEC 61010-1, providing safety and peace of mind for users. It makes my work much more effective.

Solar Power / Re: Advice please

« Last post by Kimberly on February 21, 2019, 04:22:17 PM »

Solar is a serious investment and one you’ll be living with for a long time – so it’s important you engage a competent solar panel installer. You may have purchased the best equipment money can buy, but it will not achieve its full electricity generation potential if it is installed incorrectly – and the array may even be dangerous.
