How To Test Electrical Electronics Components With Multimeter For this purpose, take avo meter (or digital multimeter) and select “resistance” (in avo meter…rotate the knob to the “Ω” or resistance). now connect both terminals, i.e. both naked ends of the cable wire with the avo or digital multimeter terminals. if the meter reading shown “0 Ω”, it means cable wire is in “good condition”. Set the multimeter to ‘resistance’, then attach the probes of the meter to both terminals of the switch or push button. this test should produce a reading of ‘0’. next, push the button or flip the switch to put it into the off position, then perform the test again. this test should produce a reading of ‘infinite’.
How To Test Electronic Components With Multimeter Info4eee 1. turn the dial on the multimeter to read a dc voltage. look for 20v and turn the knob to select. if you used this setting to try and measure a 40v project the multimeter would run out of range. How to measure dc voltage. set the rotary switch to the appropriate dc voltage setting, denoted by v . connect your test leads to the circuit or device you want to measure. as before, connect the common (com) test lead first and remove it last. read the dc voltage on the multimeter's display. Testing resistance. to measure resistance, which is quantified in ohms (Ω), i confirm there’s no current flowing in the circuit. i set my multimeter to the ohms (Ω) setting and connect the probes across the component to get a reading. resistance test: set to resistance (Ω). insert black probe into com, red into vΩma. To begin, make sure no current is running through the circuit or component you want to test. switch it off, unplug it from the wall, and remove any batteries. plug the black probe into the com port on your multimeter. plug the red probe into the port labeled with a v symbol (in this case, the right port). 3 comments.
