If you’re in the market for a reliable and affordable multimeter, the Kaiweets KM610S might just be what you need. This upgraded version of the KM601 model brings several improvements while maintaining a user-friendly experience. Let’s dive into the details of this device and see how it stacks up against older models.
Unboxing and First Impressions
Inside the package, you’ll find a hard case with a zipper, which contains:
The KM610S multimeter
A user manual (available in multiple languages)
Probes for measurements
A temperature sensor
A USB charging cable
Compared to older models, the inclusion of a hard case is a nice touch, as it helps protect the device during storage and transport.
Design and Build Quality
The KM610S features a large, rugged, rubberized casing that enhances durability. It’s designed to withstand drops and provides better protection for high-voltage measurements. While it’s dust-resistant, it’s important to note that it is not waterproof.
Size-wise, the device is comparable to four cigarette packs stacked in pairs. The display is color but not a full TFT screen, meaning it can only turn preset segments on or off. It uses EBN technology, offering white text on a dark background, which improves readability even in bright sunlight. However, EBN screens tend to consume more energy, which leads us to power consumption.
Battery and Charging
One of the standout features of the KM610S is its built-in 2000mAh rechargeable lithium battery, a significant upgrade over the KM601, which relied on disposable AA batteries. However, instead of a standard USB charging port, it uses a proprietary barrel connector, which can be a hassle if you lose the cable.
Additionally, the device cannot be used while charging. If you attempt to use the probes while the device is plugged in, it can be unsafe and may even damage the multimeter. Always ensure the device is fully charged before use.
User-Friendly Features
This multimeter is designed with beginners in mind. Some notable features include:
Auto-off function to conserve battery (can be disabled by holding the ‘SEL’ button while turning it on).
Foldout stand for hands-free use.
Front-facing probe connections, making it easier to use while in its case.
Automatic mode that detects whether you’re measuring voltage, resistance, or continuity, reducing the need for manual adjustments.
Loud beeping confirmation when switching modes—useful but potentially annoying over time.
Testing and Performance
We compared the KM610S with a multimeter purchased six years ago, and here’s what we found:
Voltage Measurements: The readings were accurate for both high-voltage sockets (245V) and low-voltage USB chargers (5V).
Continuity Test: The built-in tester effectively determined if a cable was broken and identified unmarked wires.
Temperature Sensor: The included probes resemble food thermometers, but we couldn’t verify their accuracy without precise temperature references.
Live Wire Detection: The device correctly identified live and neutral wires and displayed an ‘H’ (high voltage) or ‘L’ (low voltage) symbol accordingly.
One downside is that measurements take a bit longer to stabilize on the display. If you need quick, responsive readings, this might be a drawback.
Final Verdict
The Kaiweets KM610S is a practical entry-level multimeter with a fair balance of features and affordability. While it has some drawbacks—such as the proprietary charging cable and slow measurement updates—it remains a solid choice for general home and garage use.
Pros:
✔ Rugged, durable build with rubberized casing✔ Rechargeable lithium battery (no need for disposable batteries)✔ Beginner-friendly automatic mode✔ True RMS measurement capability✔ Live wire detection and temperature measurement
Cons:
✖ Proprietary charging cable (easy to misplace)✖ Cannot be used while charging✖ Slow measurement response time✖ Loud beeps when switching modes
If you need a simple and reliable multimeter for everyday electrical troubleshooting, the KM610S is worth considering. However, if you require precise electronics work, you may want to explore higher-end models.
