The Klein Tools CL910 is a 2000A AC/DC auto-ranging True RMS clamp meter with integrated worklight, rated CAT IV 600V / CAT III 2000V with IP40 protection. The 2-inch jaw handles large industrial conductors. Low Impedance (LoZ) mode eliminates ghost voltages. Thermocouple input enables temperature measurement. A backlit reverse-contrast 6000-count LCD and illuminated dial ensure readability in confined spaces. Frequency range spans 10 Hz to 60 kHz. Weighs 20.7 oz with 40-hour battery life on 2 AA batteries. Built for heavy industrial, utility, and solar installation work. Covered by Klein Tools' 1-year limited warranty.
What makes the CL910 different from the 600A CL series meters?
The CL910 is rated for 2000A AC/DC with a 2.0-inch jaw opening and extends voltage range to 2000V — designed for high-current switchgear, large HVAC equipment, and service entrance conductors where 600A meters are out of range.
What conductor sizes fit the 2.0-inch jaw?
Large commercial and industrial conductors including 350 MCM, 500 MCM, and bundled service entrance cable. Standard residential and commercial conductors fit easily within the larger jaw.
Does the CL910 include worklight and LoZ?
Yes — both are included, same as the CL810. The CL910 brings the full CL800-series feature set (worklight, LoZ, temperature) to high-current applications.
Can it measure 2000A DC?
Yes — 2000A DC in addition to 2000A AC. Suitable for large UPS systems, data center battery banks, and industrial DC drives.
What is the CAT III 2000V rating?
It means the CL910 is safety-rated for use on building internal distribution circuits up to 2000V — relevant for medium-voltage commercial panels. Standard residential and commercial work operates well within this rating.
How heavy is the CL910?
20.7 oz — noticeably heavier than the 600A CL models due to the larger jaw assembly. This is typical for high-capacity clamp meters and the trade-off for the extended 2000A range.
