About This Product

Klein Tools Multimeter Test Kit contains Cat. No. MM300 (Manual-Ranging Digital Multimeter), Cat. No. NCVT1P (Non-Contact Voltage Tester) and Cat. No. RT105 (Receptacle Tester). The MM300 measures DC current, AC/DC voltage and resistance. The NCVT1P automatically detects standard voltage in cables, cords, circuit breakers, lighting fixtures, switches, outlets, and wires. The RT105 detects the most common wiring problems in standard receptacles.

Highlights

  • Multimeter measures up to 600V AC/DC voltage, 10A DC current and 2MOhms resistance
  • Non-Contact Voltage Tester Cat. No. NCVT1P has a bright green LED to indicate the tester is working; it changes to red and audible tones sound when voltage is detected
  • NCVT1P has a high intensity, bright red LED that illuminates and an audible tone when voltage is detected from 50 to 1000 VAC power operating range
  • Receptacle tester Cat. No. RT105 detects wiring configurations and indicates correct wiring, and identifies common wiring faults
  • Identifies open ground, open hot, open neutral, hot/ground reversed; it does not indicate quality of ground, multiple hot wires, or a combination of defects
  • MM300 multimeter tests continuity with visual and audible continuity indicators
  • Test leads included for Cat. No. MM300; batteries included for Cat. Nos. NCVT1P and MM300

                The kit has two products that require batteries, and includes batteries for each -- a set of heavy duty batteries, and a set of alkalines. Which is for which?
                ByJun 4, 2023
                1 Answer | 
                Answer This Question

                You can use either battery in either tester. When purchased separately, the non-contact tester includes alkaline batteries, the multimeter includes the carbon zinc batteries.

                    Good quality meter. Feels good in the hands, the leads are flexible enough to be useful. Not full featured but awesome for this price point

                    Quality Has Gone Downhill – Buyer Beware
                    Suggest reading reecent and verified purchases. I purchased a Klein testing kit from Home Depot, which included a multimeter and a voltage tester. While the other components worked fine, the voltage tester was an absolute disaster. When I first opened the tester (after storing it unused in a dresser drawer), I found that the batteries had been shipped inside the unit. The batteries were greasy, corroded, and completely ruined the tester (see pictures). Naturally, it wouldn’t turn on at all. I contacted Klein customer support, and they sent me a replacement. But when I received the new unit, I thought they had sent back my original one—it looked identical to the defective one I had just returned! The only difference? This time, the batteries were NOT installed—because this unit came directly from Klein, not Home Depot. Despite that, it still wouldn’t work. I tried three different sets of fresh batteries, and nothing. The flashlight briefly flickered on and died. Plugging it into a live outlet? Nothing. To confirm it wasn’t just me, I had my contractor test it. He has an older Klein tester that still works perfectly, but he agreed: these new ones are garbage. This is clearly a company-wide quality control issue, regardless of whether the tool comes from Home Depot or directly from Klein. When I called Klein again, they had the nerve to tell me that I was "abusing" the tool—because apparently opening it and pressing the ON button is abuse now. Instead of a working tester, I’m stuck with a worthless piece of junk and forced to go through their ridiculous return process again. If you really enjoy spending hours writing emails, taking pictures of brand-new, out-of-the-package defective tools, and going back and forth with customer support, then throwing your money away, Klein is your brand. I’ve spent way too much time on this, and it’s been nothing but frustration. Tried to upload the pics but HD wouldn't let me. At this point, I wouldn’t trust Klein’s reputation at all. If you need a reliable voltage tester, you’d have better luck finding an old one at a yard sale than wasting money on these new defective units.

                      Buy a better tool, MM300 multimeter will not last.
                      I buy Klein assuming longevity and reliability. This meter has failed on both accounts. After one year of good service, the meter is headed to the recycling. It currently it reads -213vac on the 600v scale, and -14.9v on the 200v scale, with no leads attached. Last time I used it I had funky readings too. Spurious results mean the tool cannot be trusted. Where the MM300 feels good and appears to be well build, please buy something better. This unit should not have the Klein name on it.

                        Amazing products
                        [This review was collected as part of a promotion.] Three amazing tools for the price of one. Multimeter measures DC current, AC/DC voltage and resistance. Non-Contact Voltage Tester detects voltage 50 to 100 has the amazing features audible , red and green lights to notify you live wires. Outlet circuit tester show you exactly what's wrong with the wire connections .You can’t go wrong buying this complete set of tools.

                          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.
