Opening the KAIWEETS Digital Multimeter package reveals a thoughtfully designed product with all the necessary accessories. The package includes:
- The multimeter unit with protective rubber holster
- A set of test leads with caps
- Temperature probe
- Two AA batteries
- User manual
The multimeter itself has a substantial feel without being overly heavy. The rubber protective casing provides a good grip and seems capable of absorbing minor impacts, though it’s not designed to withstand severe drops like higher-end professional models such as Fluke.
Construction Quality
The KAIWEETS HT118A features a solid construction with a well-designed protective rubber sleeve that covers most of the meter. The casing seems durable enough for regular use in home, automotive, or light commercial environments. The kickstand on the back is sturdy, allowing the meter to stand at a convenient angle for bench testing, though some users reported receiving units with warped stands.
The battery compartment is accessible via a single screw, which is straightforward but not as convenient as thumb-screw designs found on some higher-end models. One design aspect that confused some users is how to access the internal fuses. The rubber casing needs to be removed (which can be somewhat challenging) to reveal four screws that allow access to the interior for fuse replacement.
Display and Interface
Display Quality
One of the standout features of this multimeter is its large, easy-to-read display. The screen offers excellent contrast with black digits against a light background, making it visible from various angles and in different lighting conditions. The backlight function is particularly impressive as it stays on as needed rather than timing out after a few seconds like many competitors.
The display includes both numerical readings and a bar graph, providing both precise measurements and visual indication of changes. The 6000-count resolution offers good precision for most applications, though it’s not as high as some more expensive professional models.
Interface and Controls
The rotary selector switch feels solid and provides clear tactile feedback when changing between measurement functions. The buttons are responsive, though some users noted they were a bit stiff when new.
A particularly innovative feature is the illuminated input jack indicators that light up to show which ports to use based on the selected function. This is extremely helpful for beginners or intermittent users who might otherwise damage the meter by using incorrect connections.
The auto-ranging feature works efficiently, quickly determining the appropriate measurement range without requiring manual adjustments. For those who prefer manual control, the RANGE button allows for specific range selection.
Measurement Capabilities and Accuracy
Voltage Measurement
The KAIWEETS HT118A provides accurate voltage readings for both AC and DC applications. According to the specifications, the accuracy for DC voltage is ±(0.5% + 3) for voltages from 600mV up to 1000V, which is impressive at this price point. In practical testing, the readings align well with more expensive meters, with most users reporting that measurements were within 0.1% of readings from professional-grade equipment.
The AC voltage measurement includes a True RMS feature, which is crucial for accurately measuring non-sinusoidal waveforms common in modern electronics. This is a significant advantage over average-responding meters in the same price range.
Current Measurement
Current measurements are handled through different input jacks depending on the expected amperage, with fused protection for both mA and 10A ranges. The meter provides accurate readings, though some users noted that for current measurements above 5 amps, the meter should only be used for short durations to prevent overheating of the internal shunt resistor.
For high-current applications, users may want to consider a clamp meter instead, which KAIWEETS also offers in their product line.
Resistance, Continuity, and Diode Testing
The resistance measurement function works well, though some users noted that it takes a few seconds to stabilize on very low resistance readings. The continuity tester is particularly responsive with no noticeable lag, providing an immediate audible confirmation when a circuit is complete.
The diode test function not only checks diodes but also supplies enough power to light up LEDs for visual confirmation, which is a handy feature for electronics work.
Capacitance, Frequency, and Temperature
Additional functions include capacitance measurement, frequency counting, and temperature measurement via the included K-type thermocouple. The capacitance function is accurate for most general applications, though it displays readings in nanofarads rather than the more common microfarads, requiring mental conversion.
The temperature probe received mixed reviews, with some users reporting readings 10-13 degrees off from known references. However, as most users noted, temperature measurement is a supplementary rather than primary function for a multimeter.
Non-Contact Voltage Detection
The NCV (Non-Contact Voltage) function allows for detecting live wires without making direct contact. This feature works reasonably well, though it requires being quite close to the source for accurate detection, especially when trying to differentiate between hot and neutral wires.
Special Features
Built-in Flashlight
The multimeter includes a built-in LED flashlight on the top of the unit, which can be activated by holding the designated button for two seconds. While not exceptionally bright, it provides enough illumination for working in dimly lit electrical panels or checking connections in darker areas.
Data Hold and Max/Min Functions
The DATA HOLD function allows you to freeze the current reading on the display, which is invaluable when taking measurements in hard-to-reach places where you can’t see the screen. The MAX/MIN function records the highest and lowest readings during a measurement session, useful for monitoring fluctuating values.
Auto Power-Off
To conserve battery life, the meter automatically powers off after a period of inactivity. Some users felt the auto-off timer was too short, but most appreciated the feature for preventing battery drain when the meter is accidentally left on.
Test Leads and Accessories
Test Leads Quality
The included test leads are adequate for the price point, featuring PVC insulation that is somewhat stiff, especially in colder temperatures. Many users recommended upgrading to silicone leads for improved flexibility and durability, especially for professional use. KAIWEETS offers compatible silicone leads separately that also come with various adapters for different applications.
Temperature Probe
The included K-type thermocouple allows for basic temperature measurements, though as mentioned earlier, its accuracy is not the strongest feature of this multimeter. Some users reported issues with unstable readings when the leads were moved, suggesting potential connection problems with the banana plugs.
