Frequently Asked Questions - UT222 Uni-T

How do I measure DC voltage with the UT222?

Set the rotary switch to DCV, connect the test leads (red to VΩ, black to COM), and touch the probes to the circuit. The reading appears on the LCD.

What is the maximum voltage the UT222 can measure?

The UT222 can measure up to 1000V DC and 750V AC. Do not exceed these limits to avoid damage or injury.

How do I test continuity?

Set the dial to the continuity symbol (diode/beep). Connect probes across the circuit. If resistance is <50Ω, the buzzer sounds.

How do I replace the battery?

Turn off the meter. Remove the screw on the battery cover. Replace with two AAA batteries, observing correct polarity. Reattach cover.

What safety precautions should I take?

Always use the correct range and function. Do not measure voltage in a circuit above the rated CAT level. Inspect test leads for damage before use.

Why does the display show 'OL'?

'OL' means over limit. The measured value exceeds the selected range. Switch to a higher range to get a reading.

Can I measure AC current?

Yes, set the dial to ACA (or A~) and select the appropriate range. Connect the meter in series with the circuit.

What does the 'HOLD' button do?

The HOLD button freezes the current reading on the display. Press again to release.

How do I clean the UT222?

Wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. Keep the terminals clean and dry.

What accessories are included?

The UT222 typically includes test leads, a user manual, and a battery. Additional accessories like alligator clips may be sold separately.
