Design and Build Quality

The Kaiweets KM601 digital multimeter stands out for its design and build quality. It has a traditional appearance, similar to older multimeters, with a compact and lightweight rectangular plastic case measuring about 6.5 x 4.37 x 2.13 inches and weighing only 1.1 pounds. It makes it easy to carry around, making it convenient for users who are always on the move.

Instead of the typical rotary knob, it features a red Auto/Func button that smoothly switches between Auto and manual modes. There are also four additional buttons on the sides. The RANGE button is used exclusively in Manual Mode for mA, voltage, and resistance tests. The SEL button lets you switch between DC and AC readings as a backup in case the Auto mode encounters any rare issues. The REL/HOLD button helps identify differences in voltage, mA, or resistance readings, and holding it for a few seconds clears stored data.

One unique feature is the presence of four LEDs under the buttons. These LEDs act as guides for probe placement, making it easier to take specific measurements in manual Mode. It is especially helpful for non-professional users who might find it confusing to determine which of the four identical ports at the bottom of the device to use. Although some users have noted that the bottom jacks can be inconvenient for certain tests, it’s important to mention that the first jack is designed for the 10A range, suitable for currents over 200mA.
