I understand your point Frank, you get what you pay for LOL. I only paid $14 shipping included from China so I dont expect a top of the line meter
There is at the back two adjusting screws for the volts and amps calibration. If I connect the DVM as per my last schematic and it will show 99.9A...
It worked Frank but……….
My experiment with this Volt / Ampmeter is with a 12VDC /5A power supply unit along with a 12VDC computer cooling fan. I hope I understood correctly but when I connect everything as per attached schematic the amps reading took a few seconds to show a value of 99.9A; then...
Sorry Frank but I don't see where the black from the DVM and the red from the power supply will go
Perhaps on the attached simple schematic you can tell me how?
Thank you
Thank you Frank for the help
Measuring between the yellow / black looks like there is no continuity because my tester shows just 1. Perhaps I should have the power to the ampmeter connected?
When you say "Try, red to PSU + output, black to PSU - output, yellow to load" the yellow to load where...
I have a digital Volt / Amp meter rated: Operating voltage: DC 4.5 ~ 30V, Measure voltage: DC 0 ~ 100V, Measure current: 100A (require external shunt), Operating current: <20mA.
This meter has a Black / Red wires for the 4.5 – 30VDC power to the meter and 3 wires Red / Black / Yellow to connect...
