multimeter

Set your multimeter to diode mode. This activates a small forward bias voltage, mimicking the typical operating condition of a transistor.

I have read different ways or reasons that could affect the measurement of multimeter readings. I am measuring resistance across a circuit at two points using a kelvin probe (Keithly 5808). I get different readings every time I take measurements of the same circuit in intervals of time. I tried...

Hello, I have an ESC which is rated for 40A. I want to make sure that the 3 phase motor to which it is connected is getting sufficient voltage. How do I connect my multimeter to the ESC to measure voltage correctly? Should I just run the ESC at 80% PWM and measure 2 of the 3 outputs from the...

My digital multimeter starts fluctuating while I bring it near to my started bike even if the probes are not connected to any where .I can't read any value during that time.Therefore I cannot check my bike electrical circuit.My multimeter shows correct values when I connect to home ac supply...

Hello i have a wellhise wh-890d multimeter. Yesterday i was trying to charge a motorbike 12v battery i unplugged the charger to check voltage then i checked the amp it is taking then i forgot the probe was in the amp hole (left 20A hole on the photo) then i put the meter on voltage mode and i...

Hi everyone. I have a several decades old analog multimeter, which works fine except that the needle stops at slightly different position if the movement goes up, than if it goes down. As an example. If I probe 10 volts DC (12 V scale), the meter stops at aprox 9 V. If I change to 3 V scale...

Hey, I'm buying my second, better, multimeter (first one costed 3 € : ) ) and I have this checklist: * auto ranging * capacitance measurement at least up to 10mF (I see a lot under 1mF and that sounds pretty useless) * ? hFE - how important is this one? It sounds pretty useful to me * I've...
