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.

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.
- 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 damps, 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. II is a convenient and safe method for noncontact detection.
Note: This function is very suitable for detecting the circuit fault in the wire, safe and fast! -
(4). Clamps and lamps corresponding table:
Battery Replacement
Pay attention to the battery polarity!
- Make sure the clamps have moved away from wires, don’t replace the batteries during measurement.
- Press “POWER” to turn off the instrument.
- Loosen the screw, and then remove the battery cover.
- Replace the batteries with new ones, notice the polarity.
- Put the battery cover back in place, and tighten the screw.
- Press “POWER” to check whether the instrument can be turned on normally, if ii cannot be turned on, please check if the battery power is sufficient or repeat step 3.
