Klein Tools CL110 – Frequently Asked Questions

1) Will the Klein Tools CL110 clamp meter fit around a 1-inch conductor or a service entrance cable?
The CL110 has a 1.12 inch (2.9 cm) jaw opening, so it clamps a single conductor up to about an inch across. That covers most branch circuit and feeder conductors, but it will not go around a bundled service entrance cable or a large parallel-run conductor. If the conductor is bigger than 1.12 inches, you need a larger-jaw meter.
2) Can I use the Klein CL110 on a 480V three-phase panel?
Its rating is CAT III 600V, and the meter reads up to 600V AC and 600V DC, so a 480V distribution panel is within range. CAT III covers fixed installation and distribution level work. It is not rated CAT IV, so do not use it on the service entrance or line side of the main disconnect.
3) Does the Klein CL110 measure DC amps?
No. The clamp on the CL110 reads AC current only, up to 400A. DC is covered for voltage only, up to 600V DC through the test leads. If you are troubleshooting DC motor circuits, solar strings, or battery banks and need DC amperage, this is the wrong meter.
4) What comes in the box with the Klein CL110 clamp meter, and do I need to buy anything to start testing?
It ships ready to work: carrying case, test leads, and three AAA batteries are included. The leads are what you need for the voltage, resistance, and continuity functions, since only the current measurement goes through the clamp. Nothing else is required to put it into service.
5) Is the Klein CL110 good enough for a maintenance tech working panels and HVAC units all day?
That is the work it is built for. It survives a 3.3 foot (1 m) drop, weighs 10.1 oz so it rides in a pouch, and the 2000 count LCD is backlit for dark mechanical rooms and crawl spaces. Klein specifies it for residential, office, and light-industrial environments up to 6562 feet of altitude and 32 to 122 degrees F. Heavy industrial process environments are outside that envelope.
6) Will the CL110 auto-ranging clamp meter check continuity and resistance, or do I need a separate multimeter?
No separate multimeter needed for basic troubleshooting. Through the test leads it reads AC and DC voltage to 600V, resistance to 20M ohms, and continuity. The clamp handles AC current to 400A. What you do not get is DC current, so pair it with something else only if your work is DC-heavy.
7) Do I have to keep switching ranges on the Klein CL110 while taking readings?
No, it auto-ranges. The meter picks the measurement range itself and shows the result on the 2000 count backlit LCD, which matters when you are one-handed in a panel. It also shuts itself off after 15 minutes to save the batteries and flags a low battery before it dies on you.
8) What are the replacement part numbers for Klein CL110 test leads and accessories?
Klein lists 69401, 69409, and 69410 as the replacement parts for the CL110. Order by those numbers rather than a generic lead set if you want the correct fit for the meter.
9) How big is the Klein CL110 clamp meter, and will it fit in a tool pouch?
It measures 8.7 inches long, 3.02 inches wide, and 1.61 inches high, at 10.1 oz. That is a one-hand meter that drops into a standard pouch or the included carrying case without taking a dedicated tool bag pocket.
