Since the multimeter is measuring resistance as a calculation of an observed voltage drop due to an injected current, having the circuit powered on will cause interference with the resistance ...

Measuring resistance is a simple enough concept ... a sensibly sized constant current to the load, the voltage to be measured is too small for conventional multimeter. To overcome the problem ...

In Figure 1, resistor R SER provides voltage ... The voltage in Figure 4was measured at a zener-diode current of 2.8 mA. Figure 4 Measure the voltage across a zener diode with a digital multimeter.

You can apply a short circuit and measure ... a digital multimeter to the multimeter terminals if you need a more accurate measurement. You can use a suitable rotary switch or a variable resistor and ...

Still, any high-end digital multimeter can accurately measure currents down into the microam Measuring current is always a nuisance because you have to break the circuit to put the measuring ...
