Now let’s jump on Klein MM400, an auto-ranging multimeter designed by electricians for electricians.
The MM400 might not have all the fancy features, but it’s really good at doing its job well. It can test lots of things including measures temperature, frequency, capacitance, continuity, diodes, and duty cycle. While the capacitance range may not soar to the skies, capping at 200µF. It can measure up to 600V AC/DC voltage, up to 10 amps of current, and up to 40 Ohms of resistance.
The MM400 is designed smartly with a rubber cover that makes it easier to hold and can even survive a drop from three feet because of the rubber protection. The screen is big and easy to read (count of up to 4000), with a backlight for visibility in low-light conditions.
It includes a low battery indicator, a data hold function, and a Min/Max function to record signal variations. It comes with a CAT III 600V safety rating, suitable for various electrical setups.
Now, I won’t pretend that the MM400 can match the robustness of its higher-tier counterparts like the MM600 or MM700, but for its price point, it offers great value.

What Users Say About Fluke 101 vs Klein MM400
Let’s hear what users have to say about the Fluke 101 and the Klein MM400.
Regarding the Fluke 101, one user who rebuilds old vacuum tube volt meters raves about its performance. They regularly use it to calibrate and troubleshoot circuits in 50-60-year-old technology. After almost a year of consistent use, they haven’t had to change the batteries yet. The auto shut-off feature gives them peace of mind. Right out of the box, the resistance and voltage measurements were spot on. The only downside they mention is the lack of a kickstand, likely due to the leads coming out the bottom. However, they found a .stl file to 3D print a plastic base if needed. They also suggest that a rubber over-molded sleeve would be a nice aftermarket addition, in case the multimeter gets dropped.
On the other hand, let’s dive into a user’s experience with the Klein MM400. Initially, they had a negative encounter, but the way Klein Tools handled it turned their experience around.
