Measuring current with a multimeter requires careful setup, as it involves creating a series connection within the circuit. This means you'll need to open the circuit and insert the multimeter in such a way that the current flows through it. DC Current Set the dial to the DC current setting (A- or DCA).
To read a multimeter on an AC system, you'll need to locate the numbers and symbols on your circuit system. On an AC circuit, for example,V stands for "voltage," while a squiggly line indicates the alternating current. If you want to test a DC circuit, switch the setting on your multimeter to VDC or DCV.
Turn the dial to the DC voltage mode. Select a range higher than the battery’s voltage if the multimeter is not auto-ranging. Attach the red probe to the positive terminal. Attach the black probe to the negative terminal. Look at the digital display for the voltage reading. Ensure the reading is stable before recording the value.
If the needle of an analog multimeter points below zero even at the lowest range, then your "+" and "-" connectors are probably backwards. Switch the connectors and take another reading. If there is a mirror behind the needle of your analog multimeter, turn the meter left or right so that the needle covers its own reflection for better accuracy.
nt flows through the meter. The red probe c nnects to the power source. Some of the current flows through the fuse and feeds the analog-to-digital converter, while the remaining larger current flows throug the shunt and to the load.When the inductive clamp is used, the small induced current is first amplifi
