Frequently Asked Questions - UT216B Uni-T

How do I measure AC current with the UT216B?

Set the rotary switch to the AC current range (400A or 600A). Open the clamp jaws and clamp around a single conductor. Read the value on the display. Ensure the conductor is centered in the jaws for accuracy.

How do I replace the batteries?

Turn off the meter and remove the test leads. Use a screwdriver to open the battery cover on the back. Replace the two AAA batteries, observing polarity. Close the cover securely.

What does the NCV function do?

Non-Contact Voltage detection. Place the clamp near a wire or outlet. The meter will beep and flash if voltage is detected. It helps identify live wires without direct contact.

Can the UT216B measure DC current?

Yes, select the DC current range (400A or 600A). Clamp around the conductor. Note that DC current measurement requires zero adjustment before clamping (press ZERO button).

What is the maximum voltage this meter can measure?

The UT216B can measure up to 600V AC or DC. Do not exceed this limit to avoid damage or injury.

How accurate is the UT216B?

Accuracy varies by range. For example, AC current is ±(2.5%+5 counts), DC current ±(2.5%+5 counts), AC/DC voltage ±(1.2%+5 counts). Refer to manual for full specs.

Does the meter have auto-ranging?

Yes, the UT216B features auto-ranging for most measurements. You can also manually select range using the RANGE button.

How do I measure temperature?

Turn the dial to the TEMP setting. Insert the K-type thermocouple into the input jacks (COM and VΩ). Touch the probe tip to the object. The display shows temperature in °C or °F.

What safety precautions should I take?

Always use the meter within its rated category (CAT II 600V, CAT III 300V). Inspect test leads for damage. Do not measure voltage above 600V. Remove test leads before changing batteries. Use the meter in dry conditions.

How do I clean and maintain the UT216B?

Clean the exterior with a damp cloth and mild detergent. Do not use solvents. Store in a dry place. Remove batteries if not used for extended periods. Calibration should be done annually.

USER MANUAL UT216B Uni-T

UT216 series digital clamp meters are designed for measuring high frequency currents (up to 400Hz) in railways and aerospace, server rooms, IT systems, etc. Its double injection design gives users a more comfortable grip and enhanced durability.

UT216's 6000 count display also provides precise readings for users.
