AND AD-5571 Non-Contact Voltage Tester Instruction Manual
Introduction
This manual describes how the product, the AD-5571 (NonContact Voltage Tester)
works and how to get the most out of the product.
Read this manual thoroughly before using the product and keep the manual at
hand for future reference.
Features
This product can perform non-contact voltage testing, illumination with an LED
light, and determine the non-grounded/grounded side of a power outlet.
There are two modes for non-contact voltage testing.
-
Low Voltage Response Mode (24 to 1000V)
Used for detection of voltages low voltage AC motors (90V), audio systems, arc welding, insulated cables and other weak electromagnetic AC signals. -
High Voltage Induction Mode (90 to 1000V)
Used for detection of voltages in lead-in lines and three-phase AC power supplies.
e.g.: Power distribution boxes, switchboards, various electrical appliances and electrical equipment.
Precautions for Use
All safety messages are given according to the ANSI Z535.4 (American National Standard Institute: Product Safety Signs and Labels) standard.
WARNING DEFINITIONS
The warnings described in this manual mean the following:
WARNING| This symbol indicates a potentially hazardous situation that,
if not avoided, could result in death or serious injury.
---|---
CAUTION| This symbol indicates a potentially hazardous situation that,
if not avoided, could result in personal injury or property damage.
It may also be used to alert the user about unsafe practices.
When using the AD-5571, the following safety precautions should always be followed.
WARNING
-
Please carefully read and fully understand the warnings and operating instructions before use.
-
Before using, apply the product to a known power source (such as a power outlet) to check if it works properly.
-
If the Non-contact Voltage Tester is damaged, does not operate normally, or if any abnormality is found, stop using it immediately.
Attach a notice to the product indicating that the product is “Out of Order” or move the product to a location where it will not be used accidentally.
Continued use of the product is very dangerous.
For repairs, please contact the store where you purchased the product or an A&D office.
Do not use for measurement subjects that exceed the rated voltage (1000V).
If the voltage to be measured exceeds AC 30V, there is a risk of electric shock, so please use carefully. -
Even if the red LED does not blink or the buzzer does not sound when using a Non-contact Voltage Detector, there still may be power running through the measurement subject.
The Noncontact Voltage Tester Detector can only detect when there is a large enough AC voltage source to create an electrostatic field that is strong enough to be detected.
If the electromagnetic field is weak, it may not be detected.
In addition, false detections may occur if there is interference from a high- frequency switching power supply or other sources of electromagnetic waves. -
If a low battery warning is displayed, stop using the product immediately and replace with new batteries.
-
Since live wires are measured, use insulating protective equipment such as electric rubber gloves and electric insulating rubber boots to prevent electric shock accidents.
CAUTION
Repair
Internal servicing or adjustment of the product must be performed by a
qualified person.
- Do not apply strong impacts, vibrations, or electrical shocks to the product as they may cause the product to malfunction.
- Avoid using the product in places where are sudden changes in temperature, high temperature, high humidity, or high dust content.
- This product is not waterproof. Do not use it in water or in places where it may be directly exposed to water.
- To prevent hazards, do not use the product in the presence of flammable gases.
- Do not look directly into the light of the LED light. Doing so can cause other forms of eye damage.
Overvoltage category
This Non-contact Voltage Tester conforms is CAT IV (1000V) of the safety
standards (EN61010 series, JIS C 1010 series), where the safety level is
specified in terms of overvoltage categories, classified as CAT Ⅰ to CATⅣ as
follows.
- CATⅠ: Circuit with overvoltage control on the secondary side, routed from the power outlet through the power transformer.
- CATⅡ: Primary side of devices which have power cables connected to a power outlet.
- CATⅢ: Circuits from the primary side of devices that draw electricity directly from a distribution board and from the branching units of equipment to the power outlet.
- CATⅣ: Electrical meters and primary overcurrent protection devices for use on lead-in lines.
Never use a measuring instrument rated with a small CAT No. to measure an
object with a larger CAT No., as this may lead to a serious accident.

Descriptions for each parts
-
A. Status display panel The LED lights up when the power is turned on.
The color of the LED indicates the status of the non-contact voltage tester. LED Color| Status
---|---
Red| High Voltage Induction mode
Green| Low Voltage Response Mode
Yellow-green| Low battery -
B. Power button
Short press: Turns power on, switches measurement mode
Long press: Turns power off -
C. LED
light button: Turns LED light ON / OFF
How to Use
Turn on the Non-contact Voltage Tester
If you press the power button while the power is off, the buzzer sounds twice,
the Non-contact Voltage Tester turns on, and the status display panel lights
up in red.
The Non-contact Voltage Tester goes into standby mode in high voltage
induction mode.
LED light
Each time you press the LED light button, the LED light turns on or off.
The LED light can be used even when the Non-contact Voltage Tester is turned
off.
The product turns off automatically after about 5 minutes.
Non-contact voltage tester
Bring the detection part close to the AC voltage measurement subject or power
outlet.
When the product detects an AC voltage signal, the red LED on the tip of the
detection part blinks and the buzzer sounds.
The closer the product is brought to the AC voltage measurement subject, the
faster the red LED blinks and the buzzer sounds more frequently.
The ungrounded and grounded sides of a power outlet can be determined using
the product by inserting it into two of the receptacles of the power outlet
and comparing the difference in the detected signal strengths.
Apply the product to the measurement subject correctly as shown in the figure below.
| Cannot detect voltage correctly
---|---
| Position the product parallel to the measurement subject.
Selection of detection range
When the product is turned on, it starts in “High Voltage Induction Mode”,
which has an AC voltage detection range of 90 to 1000 V, and the status
display panel lights up in red.
When the power button is pressed once, the status display panel lights up in
green and switches to “Low Voltage Response Mode”, which has an AC voltage
detection range of 24 to 1000 V.
If the measurement subject is known to exceed 90 V in advance, it is
recommended that you use the “High Voltage Induction Mode”.
Auto power off
This is a function that automatically turns off the power to save battery
power.
If the product is not used for about 5 minutes, the buzzer sounds once and the
product is turned off.
Turning off the product
When the power button is pressed and held for 2 seconds or longer, the buzzer
sounds once and the product turned off.
Low battery display
When the battery voltage is low, the status display panel blinks yellow green
three times and the buzzer sounds once before the product is turned off.
Replace the batteries.
Maintenance
Installing / Replacing Batteries
