Product Information
Full details
The KAIWEETS Digital Multimeter HT118A is designed for DIY enthusiasts, automotive technicians, and electricians who need a versatile and accurate tool for diagnosing electrical issues in homes, vehicles, and industrial settings. Its key benefit is its comprehensive measurement capabilities, including AC/DC voltage and current, resistance, and specialized functions like non-contact voltage detection and temperature measurement, all presented on a clear dual display. A potential caveat for advanced users might be its auto-ranging feature, which, while convenient, offers less manual control than some professional-grade meters.

FAQs
What is the CAT rating and what does it mean?
The meter is rated CAT III 1000V and CAT IV 600V. This rating indicates the safety level for transient overvoltages in different electrical environments. CAT III is for fixed installations (e.g., building wiring), and CAT IV is for measurements at the source of the electrical supply (e.g., service entrance).
How do I measure AC voltage?
Set the dial to the 'V~' (AC Voltage) symbol. Connect the black probe to the COM jack and the red probe to the VΩmA jack. Touch the probes to the points across which you want to measure the voltage. The auto-ranging feature will select the appropriate range.
Can this multimeter measure temperature?
Yes, this multimeter includes a temperature measurement function. Use the dial to select the 'TEMP' or °C/°F setting. Connect the included temperature probe to the COM and VΩmA jacks and place the probe tip on the object whose temperature you want to measure.
What is the difference between the VΩmA and 10A jacks?
The VΩmA jack is used for measuring voltage, resistance, capacitance, frequency, diode tests, continuity, and currents up to 200mA. The 10A jack is specifically for measuring higher DC or AC current values, up to 10 Amperes.
How does the auto power-off feature work?
The auto power-off feature conserves battery life by automatically shutting down the multimeter after a period of inactivity (typically around 15-20 minutes). You can temporarily disable this feature if needed, or simply turn the dial to power the device back on.
What is included with the KAIWEETS HT118A multimeter?
The package typically includes the KAIWEETS HT118A multimeter, a pair of test leads, a temperature probe, a protective silicone case, batteries, and a user manual.
How long is the warranty and technical support?
KAIWEETS offers a 36-month (3-year) after-sale service and lifetime technical support for this product.
Troubleshooting
Multimeter displays 'OL' or '1'.
This indicates the value being measured exceeds the selected range. For auto-ranging, ensure the leads are in the correct ports. If manual range is selected, switch to a higher range or select a different function.
No reading or erratic readings.
Check that the test leads are firmly connected to the multimeter and the circuit being tested. Ensure the leads themselves are not damaged. Verify the function and range are set correctly. Clean the probe tips.
NCV function not detecting live wire.
Ensure the NCV function is selected and the sensitivity is adjusted if applicable. The probe end of the multimeter must be close to the wire. Check if the wire is actually live by testing with the leads.
Device won't turn on.
Check if the battery is low and needs replacement. Ensure the battery is inserted correctly. If the issue persists, contact technical support.
Pros and Cons
Pros
- Versatile measurement capabilities cover most common electrical testing needs.
- Enhanced safety features like NCV detection and high-voltage protection.
- Clear, large dual LCD display with a helpful bar graph.
- Built-in flashlight and kickstand improve usability in various environments.
- Durable construction with a protective silicone case for drop resistance.
Cons
- Auto-ranging may not satisfy users requiring manual range selection.
- Temperature measurement might be less precise than dedicated thermometers.
- Limited to 10A current measurement, potentially insufficient for heavy-duty industrial applications.
- Battery checking function is basic and may not replace specialized battery testers.
Setup, Compatibility & Care Instructions
Setup:
- Ensure the multimeter is powered off before connecting test leads.
- Insert the black test lead into the COM jack and the red test lead into the appropriate jack (VΩmA or 10A) based on the measurement type.
- Select the desired function and range using the dial switch.
- For AC/DC current measurements above 200mA, use the 10A jack for the red lead.
Compatibility:
This multimeter is compatible with standard electrical testing scenarios across household, automotive, and light industrial applications. It is designed to work with circuits up to its rated safety limits (CAT III 1000V, CAT IV 600V).
Care:
- Cleaning: Use a dry, soft cloth to clean the exterior. For stubborn dirt, use a slightly damp cloth and allow the device to dry completely before use. Avoid solvents or abrasive cleaners.
- Storage: Store the multimeter in its protective case or a dry, safe place away from extreme temperatures and moisture.
- Battery Replacement: When the low battery prompt appears, replace the battery with the specified type (check manual for exact type) to ensure accurate readings.
- Fuse Replacement: If a fuse blows, replace it with the exact type and rating specified in the manual to maintain safety and prevent damage.
