To begin, allow’s measure voltage on a AA battery pack: connect the probe that is black COM additionally the red probe into mAVО©. Set the multimeter to “2V” into the DC (direct present) range. The majority of portable electronic devices use direct present), maybe perhaps perhaps not alternating electric current. Connect the probe that is black battery pack’s ground or ‘-‘ as well as the red probe to power or ‘+’. Squeeze the probes having a pressure that is little the negative and positive terminals associated with AA battery pack. If you a fresh battery pack, you need to see around 1.5V regarding the display (this battery pack is unique, so its voltage is somewhat more than 1.5V).
If you should be measuring DC voltage (such as for instance a battery pack or even a sensor hooked as much as an Arduino) you intend to set the knob in which the V features a line that is straight.
