Pick out a random resistor and set the multimeter to the 20kΩ setting. Then hold the probes against the resistor legs with the same amount of pressure you when pressing a key on a keyboard. The meter will read one of three things,, 1, or the actual resistor value.

REL Key: Press the “REL” key, the meter enters relative measuring mode, “REL” is displayed on the LCD and the present reading becomes the reference value and displayed on the display. Relative measurement R EL =measurement value-Reference value. • Do not apply more than the rated voltage, as marked on the meter, between terminals or between any terminal and earth ground. • Before use, verify the meter’s operation by measuring a known voltage. • When measuring current, turn off circuit power before connecting the meter in the circuit. Remember. Set your multimeter to the ohm meter on the selector knob. Plug the black probe into the common port. Insert the red probe into the jack marked for ohms. Gently tap the red and black tips together. Avoid touching the metal parts with your fingers while you do that. Your reading should be ohms or less.

If you're anything like me, manually opening cans is the bane of your existence — they're hard to puncture, they catch constantly, and they're often left with treacherous sharp edges. That's why it's extra important to have the best manual. For an instruction manual to be effective, it needs to be logically organized, easy to navigate through and written in clear language. People don't typically read an entire user manual, according to Online-Learning. It's more likely that us. According to data collected by the AAA, the average motorist pays cents per mile, or $9, per year, when they buy a new car. Small sedans, SUVs, hybrids and electric vehicles are the cheapest to run while pickup trucks cost way more.
