Frequently Asked Questions - UT262E Uni-T

How do I measure AC voltage with the UT262E?

Set the rotary switch to V~. Insert the black lead into COM and red lead into VΩHz. Connect probes in parallel with the circuit. Read the display.

What does the 'OL' indication mean?

OL stands for Overload. It means the measured value exceeds the selected range. Switch to a higher range or avoid measuring high voltages/currents without proper setting.

How do I replace the battery?

Turn off the meter, remove the test leads. Unscrew the battery cover screw on the back, open the cover, replace the old 9V battery with a new one, and close the cover.

Can I measure current without breaking the circuit?

No, for DC/AC current measurement, you must connect the meter in series with the circuit. Break the circuit and insert the meter between the open ends.

What is the maximum voltage I can measure?

For DC voltage, up to 1000V. For AC voltage, up to 750V. Do not exceed these limits to avoid damage or injury.

How do I use the capacitance measurement function?

Set the rotary switch to CAP. Discharge the capacitor completely. Insert the capacitor leads into the dedicated input jacks (or use test leads). Wait for stable reading.

What does the 'AUTO' range mean?

In AUTO range mode, the meter automatically selects the best measurement range for the signal. You can also manually select a range by pressing the RANGE button.

How do I check continuity?

Set the rotary switch to the continuity symbol (sound wave). Connect probes parallel to the circuit. The buzzer sounds if resistance is less than about 50Ω.

Is the UT262E auto-ranging?

Yes, the UT262E features auto-ranging for most functions except capacitance and frequency. You can also manually select ranges.

What safety precautions should I follow?

Always use the correct input jacks and range. Do not measure voltage above the rated CAT limits. Remove test leads when changing functions. Use personal protective equipment when necessary.

Introduction

UT262E Non-contact Phase Detector breaks through the traditional methods of phase detection. The traditional method is to connect three exposed clips or probes to three bared live wires, so it needs to disconnect the three wires. While UT262E Non-contact Phase Detector adopts non-contact measurement, no need to disconnect wires, no need to touch high voltage bared live wires. With the three clamps clipped on the insulation layer of three phase live wires, then the phase can be detected, meanwhile sound and light indicates positive and negative states.

UT262E Non-contact Phase Detector also has the functions of live wire examination, power inspection, phase deficiency judgement, breakpoints finding, breakpoints positioning.

UT262E Non-contact Phase Detector is a convenient and fast tool for phase detection, with clear display. It improves the safety of field testing, ensures the safety of operators, increases productivity.

Operating Method

1. Phase sequence detection

Danger! High voltage! Please pay attention to safety!

(1). Clamp three phase wires with the three clamps respectively and arbitrarily.

(2). Put the wires at the position marked with “▲” “▼”

(3). Press "POWER" button, the power indicator lamp lights up blue and the buzzer sounds once. If the lamp cannot light up, maybe the battery is in low power or check the instrument, in that case, please replace the battery or repair the instrument.

(4). If the three phase sequence indicator lamps lights up and R indicator lamp lights up green, and the buzzer sounds intermittently and slowly, so it is positive phase sequence. If the three phase sequence indicator lamps lights up and L indicator lamp lights up red, and the buzzer sounds intermittently and fast, so it is negative phase sequence
(5). Press "POWER" button in power-on state, the power indicator lamp turns off and the buzzer sounds once. The power will be turned off automatically if the instrument remains idle for 5 minutes after the power is turned on, to reduce power consumption.
2. Live wire examination, power inspection, phase deficiency judgement, breakpoints finding
Danger! High voltage! Please pay attention to safety! (1). Clamp one wire with any one of clamps, if it is an electrified wire (AC 70-1000V), R, S, T lamps light up. In this way to check whether the wire is electrified.
(2). Clamp one wire with any one of clamps, if there is phase deficiency, R, S, T lamps won't light up.
(3). Clamp one wire with any one of clamps and move the clamp along the wire, if R, S, T lamps light off, it means the section wire before this point has a break. Breakpoints can be found out accurately by shortening the range of detection. It is a convenient and safe method for non-contact detection.

Note: This function is very suitable for detecting the circuit fault in the wire, safe and fast!

(4). Clamps and lamps corresponding table:
