            A:  No you cannot use this item to test a capacitor it does not have the capability of reading microfarads. This multimeter has no mfd symbol. Do not buy this product it is terrible doesn’t even work and I tried returning the very next day n was told it cannot be exchanged or returned no refund not even store credit

            by|Jul 13, 2022

            A:  The MM300 Multimeter does not test capacitance. For a multimeter that tests capacitance, please see Klein Tools model # MM400 600V Auto-Ranging Digital Multimeter

                      The Klein Tools MM300 is an affordable compact LED readout manual ranging multimeter
                      The Klein Tools MM300 is a great compact multimeter for use around the house or on a job site. The meter measures AC/DC voltage, DC current, continuity, and resistance. There also is a setting to test batteries, diodes, for continuity. The meter also has a built-in stand, and test lead holders integrated right into the meter housing. Requires 2 AA batteries which are included.

                      Pretty paperweight
                      As the pictures will indicate, the LCD screen never lit up and there were no other signs of life from this device when turned on in spite of replacing the included batteries with new AAAs and following the instruction manual to the letter. It is a nice, durable looking instrument which just doesn't work. The instruction manual included directions to remove the back in order to replace the fuses. I did this and checked the fuses which were OK. Still - no joy! Serious disappointment.

                      Very Impressive
                      This Klein MM300 Multimeter can measure AC/DC Voltage, DC Current, and Resistance. Can also test Batteries, Diodes and Continuity. Has a Hold Button and a large bright digital readout. Just make sure that you insert the test leads (Black & Red) fully into the meter. They have to click/lock into place without any gaps. This is outlined in the directions. I compared this unit with my neighbors $600 Multimeter and I found it to be 100% accurate. This meter is made out of high impact shock absorbent plastic with a built in stand and 2 clips on the back to hold your test leads in place. Each lead is about 39in. long and the tips can be removed to expose a longer test lead if needed. Uses 2 AAA batteries included and instruction manual included. Also a low battery indicator.

                      Don't Blow the Fuse!
                      This is functionally a very nice meter. It does exactly what the specifications say it does and is probably great for most people especially if they never use the current features. Just be very careful not to blow either of the current fuses. They are specialty fuses and will run you $13 each, almost half the value of the meter. The 200mA jack is fused at exactly 200mA, so in reality you can't measure current close to 200mA without risking blowing this expensive fuse.

                        I have used Klein tools for over 40 years and I bought this MM300 Multimeter to do simple household functions, and to test my cars AGM batteries. The unit works really well for me, at a very reasonable price. It is well made, robust and easy to use.
