LX - Checking Voltage Using Voltmeter


Read Article

Using a digital voltmeter allows you to take important voltage readings at the transformer, at each fixture and at the receptacle the transformer will be plugged into. Dial the digital voltmeter to the 200 ~ setting for measuring AC voltage.

Checking Voltage at Outlet

This tool tells you whether or not the 120 volt receptacle you are plugging the FX Transformer into is wired properly. Follow the tool manufacturers instruction manual to assure proper wiring on the receptacle you will be using.

This procedure should only be performed by a licensed electrician.

Checking Voltage at Transformer Lugs

Each lug should read no more than +/– 0.3 to 0.9 volts of rated output.  Both the LX-150 and LX-300 models have a 12V, 13V, and 14V lug inside the controller.  The FX MultiTap Transformer allows you the opportunity to utilize the voltage tap that will provide each circuit with the proper voltage.  For cable runs in the “distant zone” you would typically select the 13 or 14 volt tap. For cable runs in the “close zone,” you would typically install the cable run into the 12 volt tap depending upon the wattage load and size of cable.



Checking Voltage at Fixture Splice

Insert voltmeter probes into each wire connector (Optimum reading between 10.5 and 11.5 VAC for incandescant fixtures and 10-15 VAC for LED fixtures).
