Frequently Asked Questions - UT-LS15-US Uni-T

What is the UT-LS15-US AC Line Splitter used for?

It provides a safe and simple solution for measuring AC operating current of electrical devices by separating the live and neutral wires so a clamp meter can measure current without cutting wires.

How does the 10x multiplication feature work?

The splitter increases the measured current by 10 times for more accurate readings on small currents. You must divide the clamp meter reading by 10 to get the actual operating current.

What are the electrical ratings of this line splitter?

It is rated for 125V AC, 60Hz, 15A. Do not exceed these ratings.

Can I use this splitter on outlets other than US/Canadian?

No, it is designed for standard US and Canadian 125V AC outlets only. Do not use with other plug types.

What safety certifications does the UT-LS15-US have?

It is ETL Listed and conforms to UL STD. 61010-1, 61010-2-030 and CSA STD. C22.2 No. 61010-1, 61010-2-030.

What is the correct procedure to measure current with this splitter?

Plug the appliance into the splitter, plug the splitter into the outlet, power on the appliance, and use a clamp meter around the single conductor of the splitter. Ensure jaws are fully closed, then divide the reading by 10.

What maintenance is required for the line splitter?

Keep it dry, clean with a damp cloth, avoid strong impacts or drops, and do not use chemicals or solvents. Store at normal temperatures.

What environmental conditions are suitable for operation?

Operating temperature: 0°C to 50°C; humidity: max 80% up to 31°C, decreasing to 50% at 40°C; altitude: up to 7000 feet.

Can I measure currents higher than 15A?

No, the maximum current is AC 15A. Exceeding this may cause damage, short circuit, fire, or electric shock.

What do the safety symbols on the device mean?

The triangle with exclamation mark indicates you must refer to the manual for important safety information. The lightning bolt indicates hazardous voltages may be present. The '~' symbol means alternating current.

AC Line Splitter Operating Instructions

Introduction

UT-LS15-US AC line splitter provides a safe and simple solution for measuring AC operating current of electrical devices.

A power cord includes a live wire and a neutral wire insulated from each other. When measuring current flowing through a conductor with a clamp meter, a reading of zero will always be measured if the jaw clamp around the entire power cord. This because the current flowing though live wire and neutral wire is in reverse, the current magnetic fields neutralized each other. In order to accurately measure current flowing through AC lines, the two wires need to be separated, clamp any one of them after removing the insulated jacket of the power cord to perform measurement. The AC line splitter can separate live wire and neutral wire without damaging any insulation.

To obtain more accurate reading when measuring small currents, the splitter increases readings by 10 times, which can then be measured by a clamp meter. Therefore, the measurement should be divided by 10 to get the actual result.

With proper use, the AC line splitter can provide users with many years of reliable service.

Warning

• Please read, understand and follow the safety rules and instructions in the manual.
• The protection is ineffective when the safety rules and instructions are not followed.
• For use on standard US, Canadian, and other same type of 125V AC outlets only.
• Do not test current of more than AC 15A.

Maintenance

Please maintain the AC line splitter according to the followings,
1. Keep the device dry. Please use clean cloth to wipe when the case or socket is wet. No wet splitter should be used.
2. Use and store the device in normal temperatures. Using or storing it in other temperatures may shorten its service life or melt its cover.
3. Use the device gently. Strong impact or drop from height can damage the electrical parts or the case.
4. Keep the device clean. Wipe dirt off with clean damp cloth. Do not use chemicals, cleaning solvents, or detergents.

Operating Instructions

1. Plug the appliance being tested into the AC line splitter

2. Plug the line splitter into an AC outlet

3. Power on the appliance

4. Follow the AC current measurement instructions of clamp meter
5. Make sure the jaws are fully closed before taking a reading.
6. Divide the clamp meter reading by 10 to get the actual operating current of the appliance. For example, if the clamp meter displays AC 10A, the actual operating current is AC 1A.
