Premium Clamp Meter Electrical Test Kit

  • Warnings

    • Before each use verify meter operation by measuring a known voltage or current.
    • Read, understand and follow all instructions, cautions and warnings attached to and /or packed with all test and measurement devices before each use.
    • Do not use the meter during electrical storms or in wet weather, and do not use the meter or test leads if they appear to be damaged.
    • Do not attempt to measure resistance or continuity on live circuits.

  • Features

    • Clamp Meter is Automatic Ranging for Measurement and has NCVT feature
    • NCVT-3P has dual-range capabilities to detect from 12 to 1000V AC or 70 to 1000V AC for a broad variety of low-voltage or standard voltage applications
    • ET40 tests AC voltages from 12V to 240V AC at four useful levels aligned with commonly used residential voltages
    • Bright flashlight illuminates work area and may be used independent of NCVT-3P voltage detection function
    • ET40 also tests DC voltages from 1.5V to greater than 17V to 24V at four common levels
    • Meter has backlit LCD for ease of viewing in low light and is CAT III 600V, Class 2 Double Insulated
    • RT210 detects the most common wiring problems in standard and GFCI receptacles
    • CL120 Clamp Meter measure AC current via the clamp, and AC/DC voltage, resistance and continuity via test leads
    • A convenient chart on RT210 helps determine wiring conditions - open ground, reverse polarity, open hot, open neutral, and hot/ground reversed

Klein Tools CL120VP – Frequently Asked Questions

1) What tools come in the Klein Tools CL120VP electrical test kit?
Four pieces: the CL120 clamp meter, the NCVT-3P non-contact voltage tester with flashlight, the ET40 AC/DC voltage tester, and the RT210 GFCI receptacle tester. Between them you can read AC current through the clamp jaw, AC/DC voltage, resistance and continuity through the leads, check for live conductors without contact, and verify receptacle wiring.
2) Is the CL120 clamp meter rated for commercial panel work?
It is CAT III 600V, Class 2 double insulated, CE certified, with a Pollution Degree 2 rating. CAT III 600V covers distribution-level wiring such as panelboards, feeders and branch circuits in a building, but not the service entrance or utility side, which is CAT IV territory. Working voltage is 600V AC/DC.
3) How big a conductor will the CL120 clamp jaw fit around?
The jaw opening is 1.6 inches (4.1 cm), so it will go around typical branch-circuit and feeder conductors and small cable bundles. Larger service conductors or a tight bundle in a full panel gutter may not fit; plan on clamping individual conductors.
4) Do I have to select a range on the CL120 clamp meter?
No. It is an auto ranging clamp meter, so it picks the range itself once you clamp or connect the leads. Readings show on a 2000 count backlit LCD, which stays legible in a dark mechanical room or crawlspace.
5) What voltage range does the NCVT-3P in this Klein kit detect?
It is dual range: 12 to 1000V AC on the low setting for doorbell, thermostat, landscape and control wiring, or 70 to 1000V AC on the standard setting so nuisance signals on line voltage work do not trip it. It also has a built-in flashlight that runs independently of the detection function.
6) What does the ET40 tester in the CL120VP kit actually read?
It checks presence and rough level rather than giving a numeric reading. AC is indicated at four levels from 12V to 240V, matching common residential voltages, and DC at four levels from 1.5V up through greater than 17V to 24V. Good for battery, doorbell, and low-voltage control checks; use the CL120 when you need an actual number.
7) Will the RT210 in this kit test GFCI outlets, or only standard receptacles?
Both. The RT210 works on standard and GFCI receptacles and flags the common wiring faults: open ground, reverse polarity, open hot, open neutral, and hot/ground reversed. A chart printed on the tester tells you which light pattern means which fault, so a maintenance tech can read it without carrying the manual.
8) Will the Klein CL120 clamp meter survive a drop off a ladder?
It is rated for drops up to 6.6 feet (2 m). The housing is ABS over the electronics, and the meter measures 8.45 inches long by 3.5 inches wide by 1.5 inches high, so it drops into a pouch rather than riding loose in a bucket.
9) Is the CL120VP kit a single part number or do I order the testers separately?
It ships as one kit under Klein Tools part number CL120VP, with all four testers together. Kit weight is 1.78 lbs.
