Frequently Asked Questions - UT08B Uni-T
How do I measure DC voltage with the UT08B?
Turn the dial to V DC (usually a ‘V’ with straight line). Insert the black lead into COM and the red lead into the V/Ω socket. Place the test leads in parallel with the circuit and read the value. Ensure the voltage does not exceed 600 V.
Can the UT08B measure AC voltage?
Yes, it measures AC voltage up to 600 V. Select the V~ position on the dial. Use the same inputs as for DC voltage. The meter displays the RMS value.
How do I perform a continuity test?
Turn the dial to the continuity function (usually a diode symbol with sound waves). Insert the leads, touch the test points together. If the resistance is below a threshold (typically 30 Ω), the built-in buzzer sounds.
What is the max voltage the UT08B can handle?
The UT08B can measure up to 600 V AC and 600 V DC. However, safety category rating is CAT I 600 V, CAT II 300 V. Do not use on circuits above these ratings.
How do I replace the batteries in the UT08B?
Turn off the meter and disconnect the test leads. Remove the battery cover screw, then remove the cover. Replace the two AAA batteries, ensuring correct polarity. Reattach the cover and tighten the screw.
What does 'OL' mean on the display?
'OL' stands for Overload. It indicates that the measured value exceeds the selected range. For example, measuring a resistance higher than 20 MΩ will show OL. Switch to a higher range if available.
Is the UT08B suitable for measuring low voltages?
Yes, the 200 mV range allows measurement of very low DC voltages. For AC voltage, the lowest range is 200 V, so it is not suitable for low AC signal measurement.
How do I measure resistance?
Set the dial to the Ω function. Ensure the circuit is de-energized and capacitors discharged. Insert the leads and touch the resistor or circuit. The resistance value will be displayed.
Can the UT08B test diodes?
Yes, it has a diode test mode. Select the diode symbol, connect the red lead to the anode and black lead to the cathode. The forward voltage drop is displayed in volts. Reverse polarity shows OL.
What safety precautions should I take when using the UT08B?
Never measure voltage above 600 V. Inspect test leads for damage. Keep fingers behind the finger guards. Do not use in explosive or damp environments. Remove test leads before opening the battery cover.
