Pro-Tip: When measuring current on small appliances with the 69409 line splitter, use the 10x port for increased precision. Simply take the reading on your CL120 meter and divide by 10 to get the exact amperage; this is especially helpful for troubleshooting equipment with a draw below 1 amp that might otherwise be difficult to detect.
