          No, this is a big problem when trouble shooting a DC circuit.

                  I would like to have this to run tests on appliance parts at home to pinpoint which parts are bad and need replacement. Would this multimeter work for that?

                    Can this be used to test a 12v car battery?

                    Answer This Question

                    Yes, you can measure the VOLTAGE on a 12V car battery. Set your dial to the 20vdc setting located at about 10 o'clock. You cannot measure the amperage of the battery as it is greater than 10 amps DC.

                          Does this provide a sound for continuity ?

                          Yes, this manual ranging Klein multimeter has a audio sound for continuity testing

                          Can someone from Klein answer this question and address how fast the continuity signal is. One answer said that is can take as long as 3 seconds. That would be very annoying if it was really that long.

                          By|May 27, 2020

                            Yes, there is an audible signal for continuity.

                            By|May 16, 2022

                              It does beep for continuity but the response time is pathetically slow at around a full 2-3 seconds.

                                Can it test capacitors

                                The MM300 Multimeter does not test capacitance. For a Multimeter that will test capacitance, please see Klein Tools Model # MM400 (for measurements up to 200µF), MM600 (up to 1000µF), or MM700 (up to 4000µF).
