UT659A/UT659D LED Tester User Manual

I. Safety Warning

This manual contains warning information and safety regulations. Please

observe them strictly to ensure the safety of the user and tester.

Caution:

1. Please read and understand the contents of the manual before using

the tester.

2. Please be sure to understand the safety aspects of the manual in detail.

3. Uni-Trend is not responsible for any damage caused by improper use

or violation of the safety regulations in the manual.

4. This manual is subject to change without prior notice.

Safety symbol “ ” has three meanings in the manual. Users should

pay special attention to the operation with the symbol when reading.

Danger----- identifies conditions and actions that are likely to pose

serious or fatal hazards.

Warning---- identifies conditions and actions that may pose serious

or fatal hazards.

Caution----- identifies conditions and actions that may pose minor

injury or damage the tester.

This tester is a power output device. Please do not use it to test

live circuits.

This tester can output up to 30mA current/300V voltage. Please

do not touch both ends of the output test leads.

Danger

This tester is a power output device. Do not use it to test circuits

connected to vulnerable components, such as CPU on the board.

When the tester is testing at 30mA/300V, if the voltage rises but

there is no LED lit, please discontinue the test.

Warning

Do not look directly at the high-brightness LED light source for a

long time.

Do not light high-power LED lamps for a long time to avoid

overheating of the tester.

If the tester is not used for a long time, please unplug the power.

Caution

The meaning of the symbols associated with this tester:

Equipment protected throughout by DOUBLE INSULATION

or REINFORCED INSULATION

Danger, Warning or Caution

Caution, possibility of electric shock

Please read the instructions before use.

II. Features

The UT659A/UT659D LED tester supports full voltage (85V~265V, 50Hz

/60Hz) input, which can be used after powering it up for 1 minute to ensure

stable voltage output. When performing a LED test at 30mA/300V, the

LED polarity can be automatically identified (short-circuit the positive and

negative ends of the test leads continuously for about 5s to switch between

automatic identification of polarity and non-automatic identification of

polarity), and the output voltage is adaptively adjusted according to the

forward voltage drop of the tested LED. The internal chip of the tester has

over temperature, overcurrent and overload protection functions.

1. UT659A

1) When the toggle switch is placed in the 30mA/300V position, the LCD

displays the output voltage and output current.

2) When the toggle switch is placed in the position for circuit continuity

test, the LCD displays the resistance value or OL.

2. UT659D

1) When the toggle switch is placed in the 2mA/24V position for single

LED lamp bead test, automatic identification of LED polarity is not

performed.

2) The LCD only displays the output voltage.

2. Measurement Range (Function)

1) 30mA/300V:

Tests the TV backlight, LED lamp and other series circuit of multiple

lamp beads with automatic identification of LED polarity (Note: LED

Short-circuit the positive and negative ends of the test leads continuously

for about 5s to switch between automatic identification of polarity and

non-automatic identification of polarity; in the automatic identification

of polarity mode, when the backward impedance for the series circuit

of multiple LED lamp beads is too large, which is similar to open circuit

for the output of DC 300V, manually change the polarity of the test

leads for testing).

Do not discard the tester or its accessories as unsorted

municipal waste. Please dispose properly in accordance

with local regulations.
