Frequently Asked Questions - UT213B Uni-T

How do I measure AC current with the UT213B?

Set the rotary switch to the AC current (A~) range. Clamp the jaw around a single conductor, ensuring the conductor is centered. Read the value on the display. The UT213B features auto-ranging and True RMS for accurate measurements.

What is the accuracy of the UT213B?

Accuracy varies by function. For example, AC current is ±(2.5%+5), DC voltage ±(0.8%+3), and resistance ±(1%+2). Refer to the user manual for complete specifications.

Does the UT213B have auto-ranging?

Yes, the UT213B features auto-ranging for most functions, automatically selecting the appropriate measurement range for your input.

How do I replace the batteries?

Turn off the meter and remove the test leads. Open the battery compartment on the back. Replace the three 1.5V R03 batteries, ensuring correct polarity. Close the compartment and secure the screws.

Is the UT213B safe for high voltage measurements?

Yes, the UT213B is rated CAT III 600V, making it safe for most industrial and residential electrical systems. Always follow safety guidelines and use appropriate test leads.

What is the maximum jaw opening?

The jaw opening is 30mm (about 1.2 inches), suitable for conductors up to that diameter.

Can the UT213B measure temperature?

Yes, it can measure temperature from -40°C to 1000°C using the included point contact temperature probe. Set the rotary switch to the temperature setting.

How do I use the flashlight?

Press the flashlight button (usually labeled with a bulb icon) to turn the built-in LED light on or off. It is useful for working in dark environments.

What does NCV mean?

NCV stands for Non-Contact Voltage detection. It allows you to detect the presence of AC voltage without touching the conductor. Place the jaw near the conductor; the meter will beep and the LED will flash if voltage is present.

How should I clean and maintain the UT213B?

Clean the meter with a dry, lint-free cloth. Do not use solvents or abrasive cleaners. Avoid exposure to moisture, extreme temperatures, and strong magnetic fields. Store in a dry place when not in use.
